Waterbeds: Everything You Need to Know

If you’re old enough to have been around in the late 1970s and early 1980s, you may remember an explosion in the popularity of the water-filled mattress on the mainstream market.

In fact, during the height of the waterbed craze, around 20 percent of American households owned one of these beds.

Waterbeds’ popularity was due to their perceived health benefits and comfort. However, their quick decline in the mid-1990s was primarily due to the hassle of maintaining them.

Still, waterbeds have their place in the modern mattress market.

Waterbed Components

Does a water bed have water in it?

Of course, anyone could guess that waterbeds contain water. That’s not all there is to a waterbed, however. Many higher-end waterbeds have more components than just liquid.

The outside of a waterbed is made of vinyl, which is filled with water. Modern waterbeds use tubes or “bladders” rather than just filling up the whole mattress.

This makes the process of filling the bed easier. Multiple tubes and bladders also help cut down on leak potential and waves.

In addition to the water portion of the bed, waterbeds may also come with:

• A foam comfort layer
• Heating mechanisms to warm the water
• Internal support structures to eliminate the need for an extra bed frame or mattress foundation

How Do Waterbeds Work?

Waterbeds operate on a simple yet highly effective principle: using water as the primary support material instead of traditional springs or foam.

A waterbed consists of a durable vinyl chamber filled with water that conforms to the sleeper’s body shape, distributing weight evenly across the surface.

This buoyant support system minimizes pressure points on areas like the hips, shoulders, and lower back, making it particularly beneficial for people with chronic pain or joint issues.

Unlike conventional mattresses, waterbeds adapt instantly to changes in position, ensuring consistent support and spinal alignment throughout the night. To enhance comfort and prevent excessive motion transfer, many modern waterbeds incorporate internal fiber layers or baffles that reduce the wave effect often associated with older models.

1. Adjustable Firmness

One of the standout advantages of waterbeds is their customizable firmness. By adding more water, the surface becomes firmer and offers increased resistance, while removing water softens the feel and allows for deeper contouring.

This adjustability makes waterbeds suitable for a wide range of sleepers, including those who prefer either a soft, sinking sensation or a more supportive, solid surface.

Unlike fixed-firmness mattresses, waterbeds give users complete control over how much support they receive, allowing them to adjust it as their needs change over time—such as during pregnancy, injury recovery, or shifts in sleeping habits.

2. Temperature Control

Temperature regulation is another major benefit of waterbeds. Most models are equipped with an integrated heating system that allows users to set and maintain a consistent sleeping temperature.

During colder months, the water can be gently heated to provide cozy warmth, while in hotter weather, the temperature can be lowered to keep the surface cooler than a traditional mattress.

This precise control helps improve sleep quality by maintaining thermal comfort, reducing night sweats, and preventing the discomfort of a too-cold or too-warm sleeping environment.

3. Motion Reduction

Early waterbeds were known for their free-flowing water chambers, which caused noticeable waves whenever someone moved. Modern designs have solved this issue by introducing stabilizers, baffles, and fiber layers inside the mattress.

These components break up the movement of water, reducing the ripple effect and making it possible for one partner to move without disturbing the other.

Many waterbeds are now classified by motion levels (e.g., 90% motion reduction), allowing buyers to select the level of stability that suits their preferences.

4. Enhanced Durability and Longevity

Unlike traditional mattresses that can sag or lose support over time, waterbeds maintain their structural integrity for many years.

The vinyl chambers are designed to be puncture-resistant and durable, and because water does not compress like foam or springs, the bed remains evenly supportive without developing permanent indentations.

With proper care and occasional maintenance (like adding water conditioner to prevent bacteria and mineral buildup), a waterbed can last significantly longer than many standard mattresses.

5. Hypoallergenic Properties

Waterbeds are naturally resistant to common allergens like dust mites and bed bugs, thanks to their vinyl surface. Unlike fabric or foam mattresses that trap dust and allergens deep within their layers, a waterbed’s smooth surface can be easily wiped clean.

This makes it an excellent option for people with allergies or respiratory sensitivities, contributing to a cleaner and healthier sleep environment.

6. Customizable Support Options

Some advanced waterbeds feature dual-chamber designs, allowing each side of the bed to have its own water level and temperature settings.

This is particularly useful for couples with different comfort preferences, enabling one side to be firmer and warmer while the other remains softer and cooler.

Additionally, many waterbeds can be placed on hard-sided or soft-sided frames, giving users flexibility in both style and support.

Waterbed Types

There are two basic kinds of waterbed mattresses: softside and hardside. Softside waterbeds use foam to maintain their shape. Foam bolsters on all sides of the waterbed help the mattress stay rectangular, and this foam padding is covered with a fabric casing.

Hardside waterbeds, meanwhile, rely on wood rather than foam to maintain their shape.

Hardwood or softwood is used to create a frame around the waterbed, eliminating the need for an additional bed base and necessitating specially sized sheets. Hardside waterbeds may come with built-in headboards, footboards, or even storage space.

Health Benefits and Medical Use of Waterbeds

Waterbeds have been popular not just for comfort, but also for their therapeutic qualities.

Their unique ability to contour to the body, distribute weight evenly, and eliminate pressure points has made them a recommended sleep surface for individuals dealing with various health conditions. 

1. Relief for Back Pain

Waterbeds are especially beneficial for people suffering from chronic back pain. The fluid support system adapts to the natural curvature of the spine, helping to maintain proper spinal alignment throughout the night.

Unlike traditional mattresses that may create pressure on specific points like the lower back or hips, a waterbed creates a “floating” sensation by evenly distributing body weight. 

This reduced pressure means less muscle tension and spinal compression, which can significantly alleviate pain, stiffness, and discomfort for individuals with conditions like sciatica, herniated discs, or general lumbar pain. Some waterbeds also feature adjustable firmness settings, allowing users to fine-tune the level of support that feels best for their specific needs.

2. Eases Arthritis and Joint Pain

For those suffering from arthritis or other joint-related issues, waterbeds offer gentle, supportive comfort that can reduce pain and stiffness. The buoyancy of the water provides natural cushioning around inflamed joints, such as knees, hips, and shoulders, without the hard resistance often found in innerspring or foam mattresses. 

This decreased pressure can reduce inflammation and improve joint mobility, especially important during the early morning hours when stiffness is typically at its worst.

Additionally, heated waterbeds help to soothe achy joints with consistent warmth, which is often recommended by medical professionals as part of arthritis pain management.

3. Improves Blood Circulation

One of the standout therapeutic features of a waterbed is its ability to promote healthy blood circulation. When you lie on a waterbed, the even distribution of body weight minimizes pressure on arteries and veins, allowing for uninterrupted blood flow.

This can be particularly beneficial for individuals with circulatory issues, such as varicose veins, diabetes-related complications, or vascular insufficiency.

Improved circulation not only enhances overall cardiovascular health but also contributes to faster healing, reduced swelling, and decreased risk of pressure ulcers or bedsores — a critical benefit for bedridden or immobile patients.

4. Prevention of Bedsores and Pressure Ulcers

Waterbeds have long been used in hospitals and long-term care facilities to help prevent pressure ulcers, especially in patients who are confined to bed for extended periods.

By evenly supporting the body and reducing peak pressure points (typically found on the hips, back, and heels), waterbeds reduce the likelihood of skin breakdown.

Moreover, models with wave reduction or multi-chamber designs can still offer enough stability to allow for patient mobility while maintaining skin integrity. Heated waterbeds also keep the body at a stable temperature, which further promotes skin health and comfort.

5. Muscle Relaxation and Tension Relief

The heat and support of a waterbed contribute to full-body muscle relaxation.

For individuals dealing with muscle tension from physical labor, athletic activity, or general stress, the soothing warmth and fluid motion of a waterbed can loosen tight muscles and improve sleep quality.

Heated water, in particular, increases blood flow to sore muscles, speeding up recovery and reducing nighttime aches. The gentle motion can mimic the effects of passive massage, further aiding in tension relief.

6. Enhanced Sleep Quality for Fibromyalgia and Chronic Fatigue

People living with fibromyalgia or chronic fatigue syndrome often struggle with sleep due to widespread pain and hypersensitivity to pressure.

The cushioning effect of waterbeds can reduce nighttime disturbances by minimizing contact pressure on tender points throughout the body.

The heat feature can also alleviate pain flare-ups, while the motion of the water may help lull users into a deeper, more restorative sleep. Many fibromyalgia patients report feeling less sore and more refreshed after sleeping on a properly heated, soft-sided waterbed.

7. Temperature Therapy Benefits

Many modern waterbeds come with built-in heating systems, which allow users to maintain a consistent, therapeutic sleep temperature. Warmth is a well-known remedy for various health conditions, including poor circulation, arthritis, and muscle cramps.

Sleeping on a heated waterbed helps to relax muscles, reduce joint stiffness, and improve mobility in the morning.

Additionally, for individuals sensitive to cold or those suffering from Raynaud’s syndrome or hypothyroidism, this gentle warmth can make a significant difference in nightly comfort and circulation.

A Brief History of Waterbeds

Waterbeds can trace their origins back several thousand years. The first evidence of waterbed existence was found in ancient Persia, where goat-skin mattresses were filled with water to create a comfortable surface.

Fast forward from the Persians all the way to the early 1800s. Here, a form of waterbed known as the hydrostatic bed was used to prevent bedsores in patients.

This waterbed was simply a warm bath filled to the brim and covered with a rubber canvas to create the perfect hospital bed. Waterbeds were used therapeutically for bedridden patients throughout the 19th century as a precursor to modern mattresses for bed sores.

Finally, in 1968, the waterbed as we now know it was invented. The mattress was created by a design student named Charles Hall for his master’s thesis project.

Originally, this bed contained only one chamber for water, though modern waterbeds have many chambers. It also had no wave reduction, making it a free flow bed. It quickly gained popularity partly due to its ability to relieve pain and partly due to its newness and difference from the traditional innerspring mattress.

After a decade or two of taking up a large share of the mattress market, the waterbed fell out of fashion in favor of newer sleep technologies like memory foam and hybrid mattresses. Nowadays, it’s more of a novelty you run across occasionally rather than a standard feature in many homes.

Cost and Buying Considerations

Purchasing a waterbed involves more than just choosing a mattress — it’s about selecting the right system for your comfort, lifestyle, and space.

While waterbeds may appear as niche products today, they still come in a wide range of styles and price points, offering something for both budget-conscious and premium shoppers. 

1. Price Range and What to Expect

Waterbed prices vary widely depending on the type, size, stabilization system, and included features:

• Basic Hardside Models: Starting around $500–$900, these are the traditional-style waterbeds with a rigid wooden frame and full-wave motion. They’re the most affordable but also the least advanced in terms of comfort and convenience.
• Mid-Range Softside Waterbeds: Typically priced between $1,000 and $1,500, these look more like conventional mattresses, often come with minimal wave motion, and fit standard bed frames. They offer better insulation and are easier to maintain.
• Premium Softside Versions: High-end models can cost $2,000 or more. These often include advanced features like dual-chamber systems for couples, multi-layered fiber stabilization, digital temperature control, and plush top layers for extra comfort.

While initial costs may seem high, many users find the long-term durability and therapeutic benefits of waterbeds to be worth the investment.

2. Choose the Right Type: Hardside vs. Softside

• Hardside Waterbeds feature a vinyl water mattress encased in a sturdy wooden frame. They deliver the classic “floating” sensation but may require special bedding and are harder to move or integrate with modern bedroom aesthetics.
• Softside Waterbeds resemble traditional mattresses and are compatible with most standard bed frames and sheets. They consist of a water-filled bladder surrounded by foam and fabric casing, offering better insulation, motion control, and convenience. These are often preferred for their blend of comfort, functionality, and visual appeal.

Your choice will depend on whether you value the traditional waterbed feel or prefer a more practical and contemporary option.

3. Check Stabilization and Motion Control

One of the most important features in a waterbed is wave control. Basic models allow full-wave motion, which can feel like floating freely on water — appealing to some, but disruptive to others. For improved support and minimal movement:

• Look for models with fiber layers, foam inserts, or multi-chambered stabilization systems.
• Some premium beds are classified by the percentage of wave reduction (e.g., 90%, 99%) — the higher the number, the more stable the surface.

If you’re a light sleeper or share your bed with a partner, investing in a semi-waveless or waveless model will dramatically improve your sleep experience.

4. Verify the Quality of the Heater System

Temperature control is essential for comfort and health when sleeping on a waterbed. A good waterbed heater helps maintain consistent warmth throughout the night, easing muscle tension and promoting circulation. Look for:

• Digital temperature controls with precision settings.
• Energy-efficient models with built-in safety shut-offs.
• Dual heaters for softside models with separate chambers — especially beneficial for couples with different temperature preferences.

Keep in mind that without proper heating, a waterbed can feel cold and uncomfortable, especially during winter months.

5. Ensure Proper Frame and Floor Support

A fully filled waterbed can weigh anywhere from 1,200 to 1,500 pounds, depending on the size and amount of water used. This is a major consideration, especially for:

• Apartment dwellers, upper floors, or older homes with weaker floor support.
• People who frequently rearrange furniture or relocate.

Make sure to check the weight-bearing capacity of your floor and invest in a durable support frame or pedestal. Some softside models distribute weight more evenly and may be a safer option in weight-sensitive spaces.

6. Additional Costs and Accessories

When budgeting for a waterbed, remember to include additional items that may not come with the base price:

• Liners to protect against leaks.
• Conditioners to prevent algae growth and keep the water fresh.
• Specialized sheets for hardside models.
• Assembly or refill kits, if you’re planning to move or set up yourself.

Some retailers offer bundle deals or maintenance packages to offset these extra expenses.

Pros and Cons of Waterbed Ownership

As with all types of mattresses, waterbeds come with their own unique advantages and drawbacks.

Pros

Some people swear by the comfort of water beds, saying they relieve pain and pressure in a way that no other bed really can. This might be due to water’s ability to conform to each person’s unique shape. The amount of press relief a waterbed is capable of offering can make it a great mattress for side sleepers.

A waterbed’s pressure-relieving capabilities could also be attributed to the fact that many waterbeds come with a heater. Heating the water inside the waterbed can have a fantastic impact on back and leg pain. People suffering from aches and pains are basically sleeping on a giant hot water bottle. Warm water might also be great for you if you live in a place with harsh winters or if you’re a cold sleeper.

Another great thing about waterbeds is they’re hypoallergenic and resistant to stains. Because the actual bed is made of vinyl, it won’t absorb anything you spill on it. Nor will a waterbed retain dirt, dust, pollen, or other common allergens. A waterbed can be a good choice if you’re looking for a mattress for allergies.

Cons

Cost is a big problem with a lot of waterbeds. It’s possible to get a cheap waterbed, that only costs a couple of hundred dollars. However, if you want a waterbed you’ll be sleeping on long-term, you can expect to spend between $500 and $2000, depending on the size and brand.

Probably the biggest complaint about waterbeds is their setup and maintenance.

Waterbeds have to be filled after delivery, and dragging the garden hose up to the bedroom can be a real hassle. You also have to condition your waterbed at least once a year to keep the vinyl from becoming brittle, and that’s not to mention the hassle of patching leaks with a vinyl repair kit.

Speaking of leaks, this issue is another big con of waterbeds. While modern waterbeds with multiple chambers probably won’t just explode all over your home, you might still come in to find your bedroom rug soaked because one of the bladders sprung a slow leak you didn’t catch. Air mattresses can also leak, but escaping air just isn’t the mess that escaping water is.

Another complaint about waterbeds is their lack of body support. While water can conform to the body’s natural contours, it won’t offer the same resistance as sturdy foams or springs. This can be a real problem for stomach and back sleepers vulnerable to pain from sinking into the bed. As a sidenote, a mattress for back sleeping should have a medium-firm to firm feel, while stomach sleepers require a firm surface.

Another problem may arise for combo sleepers (sleepers who change positions during the night). While modern-day waterbeds don’t have as many issues with “waves” as they once did due to newer wave reduction technologies, if you move around a lot, you may experience some ripple effect.

Who Should Consider a Waterbed?

Waterbeds offer a distinctive sleep experience that combines comfort, therapeutic benefits, and customizable features. However, they’re not ideal for everyone. 

1. Individuals with Chronic Pain or Joint Stiffness

If you suffer from chronic back pain, arthritis, fibromyalgia, or joint stiffness, a waterbed can offer significant relief. The buoyant support system reduces pressure on sensitive areas and evenly distributes body weight, helping to alleviate pain and inflammation.

The optional heating system can further ease muscle tightness and improve joint flexibility, particularly helpful for morning stiffness or nighttime flare-ups. Waterbeds have long been used in therapeutic settings for this reason.

2. Sleepers Who Prefer Adjustable Firmness and Temperature Control

Many modern waterbeds allow for customized firmness by adjusting the amount of water or using wave-reducing systems with dual chambers.

Some models also feature temperature controls that let you sleep warm in the winter and cool in the summer.

This level of customization can be highly beneficial for couples with different sleep preferences or for people who experience discomfort due to overheating or cold sensitivity at night.

3. Allergy-Prone Individuals Looking for a Hypoallergenic Mattress

Waterbeds have a naturally hypoallergenic design. Unlike traditional mattresses, which can accumulate dust mites, dander, and allergens in their inner layers, waterbeds are sealed with a vinyl cover that doesn’t harbor these irritants.

They’re also incredibly easy to clean — a quick wipe-down with a disinfectant keeps them sanitary. This makes them an excellent option for people with asthma, seasonal allergies, or sensitive skin.

4. People Who Are Intrigued by the Unique Floating Sensation

Some people simply enjoy the novelty and comfort of the floating sensation waterbeds provide. The way the water conforms to your body creates a feeling of gentle cradling, which can be both soothing and relaxing.

If you’ve tried other mattress types and found them either too firm or too rigid, a waterbed may offer the pressure-free feel you’ve been missing.

5. Couples Who Want Minimal Partner Disturbance (with Dual-Chamber Models)

Modern waterbeds — especially hard-sided or soft-sided versions with dual chambers — allow each partner to control their side of the bed independently.

This not only minimizes motion transfer but also enables each person to customize the firmness and temperature on their side. It’s an ideal feature for couples with mismatched sleep needs or schedules.

Who May Not Benefit from a Waterbed?

While waterbeds have numerous benefits, they’re not ideal for everyone. Here are a few scenarios where a waterbed might not be the best choice:

• Frequent Movers: Waterbeds can be heavy and cumbersome to relocate. Draining and refilling the mattress takes time, effort, and the right equipment. If you change residences often or move your bed frequently, a waterbed may prove inconvenient.
• Apartment Dwellers with Weight Restrictions: Fully filled waterbeds are extremely heavy and may exceed the weight limits of upper-floor apartments or older buildings. Always check with your landlord or building regulations before installing a waterbed.
• Light Sleepers Sensitive to Motion: While many modern waterbeds feature wave-reduction systems, some people may still notice subtle water movement when shifting positions or if their partner moves. If you’re a light sleeper who needs a completely still surface, this might be a drawback.
• People Who Prefer a Firm or Bouncy Feel: The fluid nature of a waterbed offers less pushback than innerspring or hybrid mattresses. If you like a solid, firm feel or need extra support for heavier body types without the “sink-in” sensation, other mattress types may be more suitable.

Maintenance and Care

Taking proper care of your waterbed is essential for ensuring its comfort, performance, and longevity. Unlike traditional mattresses, waterbeds require specific upkeep because of their water-filled design and integrated heating systems.

With the right maintenance routine, a high-quality waterbed can easily last over a decade without losing support or comfort. 

Water Conditioning

To maintain clean, fresh water inside your mattress, it’s important to add a water conditioner every 6–12 months. This special solution prevents algae, bacteria, and unpleasant odors from developing inside the bladder.

Conditioning also keeps the vinyl supple and flexible, which helps prevent cracking or hardening over time. Skipping this step can lead to microbial buildup that not only affects hygiene but also shortens the lifespan of your waterbed.

Leak Prevention

Although modern waterbeds are built with durable, puncture-resistant vinyl, leaks can still occur from sharp objects, pets, or years of use. To avoid issues, regularly inspect the bladder and seams for small signs of wear or damage.

It’s wise to keep a vinyl repair kit on hand for quick fixes in case of minor punctures. Early detection and prompt patching can prevent more serious leaks that might damage your bed frame or flooring.

Heating System Care

Most waterbeds include a built-in heater and thermostat that allow you to adjust the bed’s temperature. Over time, heating pads can shift, become less efficient, or fail if not monitored.

Periodically check that the thermostat is working correctly and that the water maintains a consistent, comfortable temperature. If you notice uneven heating or cool spots, the heater may need adjustment or replacement to ensure restful sleep.

Liner and Bedding

Every waterbed should have a protective safety liner installed beneath the vinyl bladder. This liner acts as a barrier, catching any water in the unlikely event of a leak and preventing damage to your furniture or flooring.

Additionally, using specially designed waterbed sheets ensures a snug fit, preventing excess fabric from bunching up and providing a smoother sleeping surface.

Soft-sided waterbeds often allow the use of standard bedding, but hard-sided models perform best with tailored waterbed linens.

Surface Cleaning and Maintenance

To keep your waterbed hygienic and comfortable, regularly clean the vinyl surface with a mild cleaner or a designated waterbed vinyl conditioner. This removes dust, body oils, and allergens while also protecting the material from drying out and cracking.

A clean surface also helps bedding stay in place and prevents odors from developing over time.

Are Waterbeds Still Popular?

Waterbeds may no longer dominate the mattress market like they once did, but they haven’t disappeared — in fact, they continue to maintain a loyal following.

Once a cultural phenomenon in the 1970s and 1980s, waterbeds were widely appreciated for their novelty, comfort, and perceived health benefits. At their peak, nearly 1 in 5 mattresses sold in the U.S. was a waterbed.

However, shifting consumer preferences, technological limitations, and maintenance challenges caused their popularity to decline in the decades that followed.

That said, waterbeds have never completely gone out of style. Today, they occupy a niche space in the bedding industry, catering to a specific group of consumers who value their unique floating sensation and therapeutic advantages. Many long-time users remain committed to the comfort waterbeds provide, particularly those with chronic pain, arthritis, or mobility issues.

Modern waterbeds are significantly more advanced than their early counterparts. Newer models come with improved motion control, temperature regulation, dual-chamber systems for couples, and more stable support structures such as soft-sided designs that resemble conventional mattresses. These upgrades have addressed many of the complaints that caused consumers to switch to foam or hybrid beds in the past.

In a market now saturated with memory foam, latex, and hybrid options, waterbeds stand out as a customizable, pressure-relieving alternative — especially appealing to sleepers looking for something different or more tailored to their physical needs. They’re also regaining interest among wellness-conscious consumers exploring non-traditional sleep solutions.

While not considered mainstream today, the waterbed’s enduring legacy and ongoing innovation ensure that it continues to serve a passionate segment of the sleep market. For the right person, a waterbed isn’t a relic — it’s a rediscovered comfort.

FAQS

How much should I pay for a waterbed?

Waterbed costs can vary pretty widely. Are you seeking a cheap waterbed you’re only going to use as a novelty or for the occasional short-term guest? You might be able to get away with paying as little as $50 to $100.

However, for a waterbed you’re planning to use long-term, and especially a waterbed that’s going to be your main sleeping surface, you’re going to need to spend significantly more. The most expensive luxury waterbeds can easily run into thousands of dollars.

Can a waterbed pop?

Just like any bladder full of liquid, waterbeds do have the potential to pop. However, popping them is not as easy as putting a pin to a water balloon.

The bladders in a waterbed are constructed of thick vinyl. Most of the time, it would take some purposeful action to make a waterbed fully explode (think piercing it with a knife or other sharp object).

However, that’s not to say waterbeds can’t leak. Most of the time, rather than popping, a leaky waterbed will experience a slow drip from a stress crack or other small puncture. Don’t let the words “slow drip” fool you. Leaks like this can still do severe damage to your house, especially if you don’t notice them for a long time.

Do I have to change the water in my waterbed?

You don’t have to change the water in your waterbed unless you plan to move it. If you need to relocate your bed, you will have to drain it and refill it. Why? All those gallons of water inside a waterbed can weigh up to 2000 pounds. Even the world’s strongest moving team would have a tough time getting that down a flight of stairs.

Though you don’t have to change your waterbed’s water, you do need to add a waterbed conditioner to your water at least once a year to keep the vinyl supple.

When exposed to water, vinyl can eventually start to become brittle. If that happens, it may crack and leak. Conditioner prevents this from happening, and it also has the added benefit of preventing your mattress water from stagnating and developing a foul odor.

Is a waterbed supportive enough for nightly use?

That’s more dependent on your personal preferences and sleep style. Some people swear by waterbeds while others hate them. If you suffer pain in your pressure points (such as if you have arthritis or are a side sleeper), a water bed might help alleviate pressure and reduce pain in problem areas like the hips and shoulders.

On the other hand, water is not as supportive as other materials, meaning a waterbed can more easily allow the spine to fall out of alignment. This is especially the case for back and stomach sleepers, so if one of these is your sleep style, beware of the decreased lumbar support.

Are waterbeds good for side sleepers?

Yes, a waterbed mattress can be a great choice for side sleepers.

The reason is that it uniformly distributes your body weight and relieves pressure from your shoulders and hips. But the downside of a waterbed is that you can feel less support for your spine if the waterbed is not filled properly.

With the right water level and firmness balance, you can enjoy the water bed bouncier and comfortable at night.

What size mattress fits in a king size waterbed frame?

A king size waterbed frame which measures about 72 x 84 inches and usually fits a California King waterbed mattress. Some frames may also fit a regular King waterbed mattress that is around 76 x 80 inches.

To know how much water a king size waterbed holds, the water holding capacity is around 200 to 235 gallons.  It is important to check your king size waterbed frame size guide to be sure the waterbed mattress fits securely without gaps.

How long will a waterbed last?

The answer to this question depends on the quality of the particular waterbed you’re considering. Cheap waterbeds made for light use probably won’t last more than a few years.

On the flip side, properly maintained, high-quality waterbeds can last up to twenty years because their vinyl will not break down as quickly as foams and coils as long as it is conditioned and kept from extreme temperatures.

Bottom Line

Waterbeds can be fun to bounce around on when you’re a kid, and they can also be a boon to some adult pain sufferers. However, their lack of support may cause pain for other sleepers, and their high maintenance can put many people off.

If you’re considering a waterbed, it’s essential to know:

• Your sleep style
• Your preferences
• Your tolerance for the risk of leaks

The last is especially important, as there aren’t many other beds with quite the same potential for property damage. Once you take all this into account, you’ll be equipped to make an informed purchase.
