9 Benefits of a Zero Gravity Bed

NASA originally developed the zero gravity position to reduce pressure on astronauts when launching into space, and with the rise of adjustable beds, mattress companies discovered how to achieve this weightless sensation while sleeping.

Zero gravity is a setting you can activate on an adjustable bed. The setting raises both your torso and legs, leaving your body shaped like a “V.” Laying on a zero-gravity bed causes a sensation of weightlessness, similar to when you’re in zero gravity, by distributing your body weight evenly and preventing pressure build-up on any one body part.

A zero gravity bed benefits all types of sleepers and can relieve pain, enhance digestion, and improve blood circulation. We take a further look into how using zero gravity beds can enhance your sleep and your health.

Benefits of a Zero Gravity Bed:

Below are the main benefits of a zero gravity bed:

1. Minimizes Pain

When lying flat, there can be gapping between the spine and the mattress you’re laying on. As a result, the entire weight of the body falls onto certain body muscles and joints, namely around the lower back and neck, placing immense pressure on them.

In a zero-gravity sleeping position, there’s no gap between your body and the mattress, you have better posture, and the position distributes your bodyweight evenly. Less pressure on your body promotes pain relief, primarily around your neck and back. It can also reduce joint pain commonly associated with arthritis or fibromyalgia.

2. Alleviates Swelling and Edema

Edema is swelling due to excess fluid trapped in your body and it typically occurs around your feet and ankles. This condition can be a result of many issues, including congestive heart failure, obesity, diabetes, and prolonged periods of being sedentary.

On a zero gravity bed, your legs and feet are elevated, promoting better blood flow. As a result, your swelling may reduce, minimizing your risk of deep vein thrombosis or varicose veins.

3. Promotes Heart Health and Blood Circulation

Sleeping in zero gravity is meant to reduce pressure on your body, including the heart. With less pressure on your heart, it can pump blood better, improving blood flow throughout your body.

Based on a 2017 study, researchers found young people who prioritize heart health have better brain health as they grow older. Better heart health can also reduce your risk of high blood pressure, high blood sugar, and high cholesterol.

4. Improves Snoring and Sleep Apnea

Doctors generally discourage lying flat on your back if you struggle with snoring, sleep apnea, or other respiratory conditions. This is because your tongue and jaw relax while you sleep, collapsing backward and blocking your airways.

Sleeping with your back elevated prevents gravity from blocking your throat and relieves any pressure on the lungs, helping you breathe. Breathing correctly minimizes sleep disruptions and reduces noisy sleeping for those who share a bed. Better breathing can also help improve snoring and reduce symptoms of sleep apnea.

5. Eases Heartburn and GERD

If you eat before bed, you may suffer from heartburn or GERD (acid reflux) symptoms. When you lay flat, in particular, your stomach acid and bile are more susceptible to travel up your throat. By elevating your upper body in the zero gravity position, gravity keeps the stomach acid down in your stomach, preventing pain and sleep disruptions.

6. Boosts Digestion

Sleeping at an incline helps the digestive system work more effectively than when sleeping flat. A better digestive system, in turn, promotes a healthier gastrointestinal (GI) tract. With a healthy GI tract, you can sleep without having an upset stomach. A healthy GI tract also promotes weight loss, improves your mood, boosts your energy level, and enhances your mental clarity.

7. Relieves Pregnancy Symptoms

Pregnant women commonly suffer from many uncomfortable health issues, including back pain, heartburn, edema, and acid reflux. Using a zero gravity bed frame can potentially ease all of these symptoms in turn helping pregnant women sleep more comfortably.

The zero gravity sleeping position is also a safer position for pregnant women when compared to sleeping on their backs on a flat bed. If considering mattresses for pregnancy, think about how it might flex on an adjustable bed.

8. Fosters Deeper Sleep

Insomnia is a sleep condition plaguing millions of Americans, affecting roughly one in four people every year. The sleep disorder makes it difficult to fall asleep and stay asleep, leading to a poor mood, daytime fatigue, and worsened health overall.

Although a zero gravity bed won’t necessarily solve your insomnia, the sleeping position is comfortable and helps your body relax, in turn encouraging restful and uninterrupted sleep.

9. Lifestyle Benefits

If you struggle with being tense or are unable to relax in bed, lying in a zero-gravity position eases the pressure on your body, helping you wind down.

You can also rest in the zero gravity position when you’re not sleeping. You can be comfortable and read, watch TV, use a laptop, or simply relax. The zero gravity position is useful when just resting because you don’t need extra pillows or to use a recliner to prop you up comfortably.

Some zero gravity adjustable beds have additional features you can use while sleeping or awake as well, including a massage feature and USB ports to charge your devices.

How does the zero gravity sleep position work on an adjustable bed?

Zero gravity is a setting you can activate on an adjustable bed. The setting raises both your torso and legs, leaving your body shaped like a “V.” Laying on a zero-gravity bed causes a sensation of weightlessness, similar to when you’re in zero gravity, by distributing your body weight evenly and preventing pressure build-up on any one body part.

The zero gravity sleep position elevates both the upper and lower body at specific angles to mimic a sensation of weightlessness. This posture reduces strain on the spine and joints by distributing body weight evenly, allowing for better alignment of the neck, back, and legs. 

The slight elevation also promotes optimal lung expansion, improving breathing during sleep. People with back pain, sleep apnea, or circulatory issues can particularly benefit, as it helps ease pressure points and enhances comfort.

Moreover, this position can be tailored to individual preferences with an adjustable bed. Many beds feature a preset zero-gravity option, but customization allows users to find the angle that best suits their comfort needs. 

It’s not just about sleep; the zero-gravity setting can also help with muscle recovery, relaxation, and reducing nighttime acid reflux by keeping the torso slightly raised.

What Makes Zero Gravity Beds Unique?

Zero gravity beds are designed to allow users to rest in a position where the body feels almost weightless. This design concept isn’t just for comfort; it’s engineered to provide tangible health benefits. 

What sets these beds apart from traditional models is their adjustability, offering relief from conditions like arthritis, poor circulation, and even digestive problems.

Modern zero gravity beds come equipped with additional features such as massage settings, memory positions, and smart technology to track sleep patterns. They’re versatile for activities beyond sleep, too—whether you’re reading, watching TV, or working on a laptop, the bed can be adjusted to offer ergonomic support. 

Their ability to shift the body’s pressure points and improve overall blood flow makes them ideal for those seeking both relaxation and therapeutic benefits.

By incorporating technology like USB ports, under-bed lighting, and voice commands, zero gravity beds have evolved into multifunctional sleep solutions that cater to both health and lifestyle needs.

Who Benefits Most from an Adjustable Bed?

1. Individuals with Chronic Pain: People suffering from conditions like arthritis, sciatica, or fibromyalgia often experience intense pain in their joints, muscles, and back. Adjustable beds allow them to customize the position to alleviate pressure on pain points, such as the lower back, neck, or hips. 
2. Those Struggling with Sleep Apnea or Snoring: Lying flat can worsen sleep apnea and snoring by allowing the soft tissues in the throat to collapse and obstruct the airway. By slightly elevating the upper body can make a major difference in overall sleep quality, especially for those with obstructive sleep apnea or loud snorers.
3. Individuals with Circulation Issues: People with poor circulation, varicose veins, or edema can benefit greatly from adjustable beds. Elevating the legs above the heart helpshelp lower the risk of blood clots forming due to prolonged periods of inactivity.
4. Pregnant Women: Pregnancy can cause discomfort due to the added pressure on the lower back, swelling in the legs, and acid reflux. The zero gravity position can help expectant mothers find a comfortable sleeping posture that isn’t achievable on a flat mattress.
5. People with Acid Reflux or GERD: Lying flat can worsen acid reflux symptoms by allowing stomach acid to move up into the esophagus, especially after meals. Adjustable beds can significantly improve sleep for those suffering from GERD and heartburn.
6. Seniors and Individuals with Limited Mobility: Older adults or those with limited mobility may find it difficult to get in and out of bed, or may suffer from chronic aches and pains. Adjustable beds can be lowered for easy access, and raised to positions that make getting out of bed less challenging. 

For those who spend extended periods in bed due to mobility issues, the ability to shift positions can also prevent bedsores and improve comfort. Additionally, the remote control feature allows for easy adjustments without having to physically move much.

7. Insomnia Sufferers: People who struggle to fall asleep or stay asleep due to discomfort may find relief in adjustable beds. The ability to fine-tune the sleeping position can help them find the most comfortable posture for rest. Combining this with features like massage and sleep tracking can improve sleep hygiene and support better sleep cycles.
8. People Who Enjoy Versatility and Lifestyle Comforts: Lastly, adjustable beds aren’t just for those with health concerns. Many people who enjoy relaxing in bed while watching TV, reading, or using their laptop find these beds ideal for lifestyle comfort. The ability to raise the upper body eliminates the need for extra pillows or a separate recliner, offering a convenient and ergonomic solution for relaxation.

Optimal Sleeping Posture for Zero Gravity Beds

Back Sleepers: The zero gravity position is especially ideal for back sleepers. By elevating the legs and torso, the spine remains in a neutral, supported position. This reduces pressure on the lower back, which can alleviate pain or discomfort, particularly for those with chronic back issues. 

Additionally, the slight elevation of the torso improves breathing and prevents snoring, making it beneficial for people with sleep apnea or respiratory issues.

Side Sleepers: While the zero gravity position is most often associated with back sleeping, side sleepers can also benefit. By adjusting the elevation of the head and legs, side sleepers can achieve better spinal alignment. 

Elevating the head helps relieve pressure on the shoulders and neck, while slightly raised legs reduce strain on the hips. Side sleepers may find that small tweaks in the bed’s incline can dramatically improve their comfort levels.

It’s important to note that not every zero gravity setting is one-size-fits-all. Adjustable beds allow users to fine-tune the angle of their head and legs to find the most comfortable and supportive position. 

Some may prefer a steeper incline, while others might need a gentler elevation for optimum comfort. Experimenting with different settings can help you find the best zero gravity posture for your specific sleep needs.

Choosing the Ideal Mattress for a Zero Gravity Bed

Selecting the right mattress for a zero gravity bed is crucial for maximizing comfort and support. The ideal mattress should be flexible enough to contour to the adjustable base while providing pressure relief and spinal alignment. 

Memory foam, latex, and hybrid mattresses are the best options, as they adapt to changes in elevation without losing shape.These materials offer cushioning for pressure points, which is essential for the zero gravity position. 

Mattresses that are too firm or too thick (over 14 inches) may not bend properly and can diminish the benefits of the adjustable frame.

When choosing a mattress for your zero gravity bed, look for options that balance softness and support, allowing the body to feel weightless while still maintaining proper posture. 

For people with specific health concerns, a medium-firm mattress usually works best, providing both comfort and necessary firmness to support the spine and joints.

Mattresses Unsuitable for Adjustable Bed Frames

Not all mattresses are compatible with adjustable bed frames due to the need for flexibility and responsiveness. 

Innerspring Mattresses with Bonnell Coils or Continuous Coils: Traditional innerspring mattresses are designed with rigid coils that lack flexibility. These mattresses don’t bend easily when the bed frame is adjusted, and using them on an adjustable frame can cause damage to the mattress over time. 

The rigid coil structure prevents the mattress from conforming to the positions offered by the adjustable bed, reducing comfort and potentially leading to early wear and tear.

Extra-Thick Mattresses: Mattresses that are over 14 inches thick are usually not recommended for adjustable beds. Thick mattresses, regardless of material, may not flex well and can obstruct the full range of motion of the adjustable frame. 

This thickness prevents the bed from achieving the desired zero-gravity effect or other positions. Users may also find it uncomfortable because the mattress will resist conforming to the base’s curves.

Mattresses with Lumbar Support Zones: Some mattresses are constructed with specialized support zones, especially around the lumbar region. These mattresses are designed for specific pressure points and are often too rigid in certain areas, making them incompatible with adjustable bed frames. 

The inability of these mattresses to flex evenly can result in discomfort and reduce the lifespan of both the bed and the mattress.

Air Mattresses: Air mattresses, while popular for temporary use, do not work well with adjustable bed bases. The air chambers inside can become damaged or deflated when the mattress is bent or adjusted repeatedly. These mattresses also lack the support and flexibility required to conform to the various positions of an adjustable bed.

Firm Mattresses: Extremely firm mattresses often lack the necessary give to mold to an adjustable base. When adjusted, these mattresses may feel uncomfortable, as they do not bend easily, making it difficult to achieve the optimal zero-gravity position. 

Over time, the pressure from trying to bend the firm material can damage both the mattress and the frame.

Safety and Zero Gravity Sleep Position: Myth vs Facts

Myth: Zero gravity is only for astronauts, not everyday sleepers. Fact: The zero gravity position has been adapted for everyday use, with adjustable beds designed to offer safe, ergonomic support for anyone.

Myth: Sleeping in an elevated position may strain the neck or back. Fact: The elevation in zero gravity beds is carefully calibrated to align the spine and reduce pressure, preventing strain rather than causing it.

Myth: This position might restrict breathing. Fact: In fact, the zero gravity position improves breathing by slightly raising the torso, reducing airway obstructions.

Myth: Adjustable beds are unsafe for elderly users. Fact: Many zero gravity adjustable beds are built with safety features like slow movements and remote controls, ensuring elderly users can adjust the bed safely and comfortably.

Cons of Sleeping in Zero Gravity Position

• Limited for stomach sleepers: The zero gravity position is primarily designed for back and, to a lesser extent, side sleepers. Stomach sleepers may find it highly uncomfortable due to the elevated head and legs, which can create unnatural angles for the neck and spine.
• Initial discomfort: While many find the zero gravity position incredibly comfortable once accustomed to it, those who are used to sleeping flat might experience initial discomfort. The slight incline can feel unnatural for people who have spent years on a traditional mattress and may require a few nights or weeks to adjust fully. This adjustment period could lead to disturbed sleep in the beginning.
• Potential over-reliance on technology: Adjustable beds are powered by electric motors, which means they are reliant on electricity to change positions. In the event of a power outage, users could be stuck in the zero gravity position or in an uncomfortable angle, disrupting sleep. Though many adjustable beds come with safety features like battery backups, it’s still a potential downside for users who rely on frequent adjustments during the night.
• Higher cost: Zero gravity beds, which are typically adjustable, can be more expensive than traditional bed frames and mattresses, making them less accessible for some.
• Not suitable for all mattress types: Innerspring and thick mattresses may not work well with the zero gravity position, limiting your mattress options.
• Reduced space: Due to the incline and the larger size of adjustable beds, couples may feel like there’s less space, or experience disturbances when one partner adjusts their side.
• Complex setup and maintenance: Adjustable beds with zero gravity settings often require assembly, setup, and regular maintenance, which can be inconvenient for some users.

FAQs

How Should Pillows Be Used in the Zero Gravity Position?

In the zero gravity position, pillows should be used minimally or strategically to support specific areas without disrupting the body’s natural alignment.

A thin pillow under the head can provide gentle neck support, but avoid thick or multiple pillows as they may cause unnecessary strain. You can also place a small pillow or cushion under the knees for added comfort, though the incline of the bed generally offers enough support on its own.

How do I set my adjustable bed to zero gravity?

Some adjustable beds have a zero-gravity preset (also called ZG or Zero-G) button on the wireless remote, so you can feel weightless with the click of a button. However, you can adjust any adjustable bed to a zero gravity position even without the preset.

Simply elevate both the upper and lower portion of the adjustable bed by 30 degrees. After doing so, your torso and thighs should be at a 120-degree angle with your knees bent and raised slightly above heart level.

Can You Achieve the Zero Gravity Position on a Regular Flat Bed?

While the true zero gravity position is best achieved with an adjustable bed, you can approximate it on a flat bed by using pillows. Place a pillow under your knees to elevate your legs and a wedge pillow behind your back to raise your upper body. However, this is not as effective as an adjustable base since it lacks the precise customization needed for optimal spinal alignment and pressure relief.

Does a zero gravity bed benefit seniors?

Yes, since senior citizens may face many of the issues the zero gravity position can resolve, including edema, muscle and joint pain, sleep apnea, and heartburn, using a zero gravity bed is very beneficial for the elderly.

Adjustable beds aren’t particularly tall either when they’re still flat, so elderly adults with limited mobility should still be able to get into bed and adjust to the zero gravity position safely. Some adjustable beds for seniors also have changeable heights.

Do Zero Gravity Beds Help Improve Sleep Apnea Symptoms?

Yes, zero gravity beds can help alleviate sleep apnea symptoms. By elevating the upper body, these beds help keep the airways open, reducing the likelihood of obstruction caused by relaxed throat muscles.

This elevation promotes better airflow, making it easier to breathe and reducing the occurrence of sleep apnea episodes. However, it’s not a cure for sleep apnea and should be used in conjunction with medical treatments, such as CPAP machines.

Is it better to sleep flat or elevated?

Sleeping elevated can improve snoring, symptoms of sleep apnea, acid reflux, lower back pain, and more. However, sleeping elevated on an adjustable bed or a wedge pillow is only suited for back and side sleepers. Also, zero gravity sleeping is only effective and comfortable when you sleep on your back.

Although stomach sleeping is the worst sleeping position for your back, if you choose to sleep this way, you cannot comfortably nor safely do so while elevated. Your body would be twisted awkwardly and only lead to pain.

How long does it typically take to adjust to a zero gravity bed?

Getting used to a zero gravity bed can vary from person to person. Typically, it takes a few nights to a few weeks to adjust. The key is to give yourself time to adapt to the new sleeping position and the way the bed supports your body. Here are a few tips to help with the adjustment:

Start Slowly: Begin by using the zero gravity position for short periods each night, gradually increasing the time as you become more comfortable.

Adjust Gradually: If your bed has adjustable settings, experiment with different angles to find the most comfortable position.

Use Proper Bedding: Ensure your mattress and pillows are compatible with the zero gravity position to avoid any discomfort.

Be Patient: It may take some time for your body to get used to the new alignment and pressure distribution, so give yourself time to adjust.

Are Adjustable Bed Frames Safe for Children to Use?

Yes, adjustable bed frames can be safe for children, especially when supervised. They allow children to find comfortable positions for reading, relaxing, or sleeping.

However, it’s important to ensure that the remote control is kept out of reach when not in use to prevent any accidental movements that might cause discomfort or injury. Additionally, teaching children how to use the adjustable settings safely is crucial for minimizing risks.

Can Zero Gravity Beds Help Reduce Joint and Back Pain? 

Absolutely, zero gravity beds are designed to relieve pressure on joints and reduce back pain. By elevating the legs and upper body, the bed helps align the spine in a neutral position, reducing stress on the lower back and alleviating tension in joints. This makes it particularly beneficial for individuals with conditions like arthritis, sciatica, or general lower back pain.

Can Zero-gravity position harm?

For most people, the zero gravity position is safe and highly beneficial, but in rare cases, prolonged use might cause mild discomfort. Some individuals may experience stiffness or discomfort during the adjustment period, especially if they’re not used to sleeping with their legs elevated.

Additionally, those who have circulation issues or very specific medical conditions should consult with a healthcare professional before using this sleeping position long-term.

How thick should a mattress be for an adjustable bed?

The best mattress for an adjustable bed is one that is under 14 inches thick. Any mattress thicker than 14 inches isn’t flexible enough and won’t bend with the base properly. With an overly-thick mattress, you won’t be able to experience zero gravity as intended.

Are adjustable beds safe?

It’s reasonable to worry about safety when bringing any large devices or furniture into your home, but adjustable beds are quite safe.

Most adjustable beds include gravity release electronic motors, meaning when you adjust the bed’s incline, the gravity release causes the bed to move slowly, allotting time for anything underneath the bed (such as a child) to move.

The beds also have power outage protection, so if for whatever reason, the power goes out, the bed won’t just slam down.

Other than that, adjustable beds are very sturdy and have between a 300 to 700-pound weight capacity. Just be sure your electronic outlets are working properly and no water has corrupted them.

Conclusion

If you are shopping for an adjustable bed or if you already have one, try out a zero-gravity sleeping position for a couple of nights and see how it helps you. Although adjustable bed frames can be expensive (around $500 for low-end models to over $3000 for top-tier beds) the health benefits of zero gravity sleep are worth it for lots of people.

By sleeping in a zero-gravity position on an adjustable bed, you can ease the symptoms of various health conditions, including GERD, obstructive sleep apnea, and arthritis, along with promoting overall better sleep.
