Best Mattresses With A Warranty

Shopping for a new mattress can be exciting. It is an opportunity for you to start getting better sleep, so you can wake up with more energy and less pain. However, purchasing a mattress is also a significant investment, and whatever model you choose should last you at least 8 to 10 years. Therefore, it is essential to buy a mattress with a comprehensive and transparent warranty. Good warranty coverage ensures your new bed will support you and keep you resting comfortably for many years.

We outline three brands selling high-quality mattresses with generous warranties. Plus, we explain what to look for in a mattress warranty and what to avoid.

Best Mattresses With A Warranty

1. Amerisleep

Amerisleep is a unique mattress manufacturer offering eight different models—five memory foam and three hybrid beds. All Amerisleep mattresses feature a Bio-Pur® comfort layer. This material is manufactured with plant-based oils, making it more breathable and more responsive than foam made with 100 percent petroleum-based oils. Amerisleep’s unique construction method is also eco-friendly and non-toxic, creating a safe sleep space for you and your family.

Amerisleep Warranty

Each Amerisleep mattress comes with a 20-year prorated warranty. This warranty provides full coverage for the first 10 years of use; this includes any possible repairs or a complete replacement if necessary. If defects form after the first 10 years, customers can pay a percentage of the cost to repair or replace the mattress. Amerisleep’s warranty covers manufacturing and structural defects, including sagging and indentations greater than .75 inches, physical flaws like cracks in the foam, and loose seams in the fabric cover.

To ensure you get the most of your mattress, Amerisleep also sells a waterproof mattress protector to ensure accidents and spills don’t permanently damage the mattress. Their stable and supportive mattress foundation will also prevent sagging and any structural defects from forming.

Amerisleep Mattresses

To help each sleeper find a mattress that is both comfortable and supportive, Amerisleep adjusts the firmness of each bed with a specific body type and sleep position in mind. For example, the AS4 and AS5 are their softest mattresses, ideal for side sleepers and lightweight individuals who need more contouring. Their AS1 and AS2 are their firmest mattresses, perfect for back and stomach sleepers.

Below, we describe two of Amerisleep’s most popular models and explain why they might be right for you.

Amerisleep AS3

The Amerisleep AS3 has a 3-inch Bio-Pur® comfort layer with a medium firmness. This mattress works well for most sleep positions, including side, back, and combination sleepers. It is firm enough to prevent spinal misalignment but soft enough to cushion and cradle the joints.

Beneath the top layer, Amerisleep includes a layer of their Affinity foam with HIVE® technology. Hexagonal cutouts across the surface of this foam are placed in five comfort zones, the head and neck, shoulders and upper back, hips and lower back, upper legs and knees, and feet. Each zone is designed to keep the spinal neutral and prevent pressure points.

Bio-Core®, Amerisleep’s firm support foam, sits in the base of the mattress to ensure the layers above do not develop indentations that could change the bed’s structure. Like the other two foam layers, Bio-Core® is backed by a CertiPUR-US® certification, guaranteeing minimal VOC off-gassing when the mattress is brought indoors.

Amerisleep AS5 Hybrid

Like the AS3, Amerisleep’s AS5 Hybrid also has a 3-inch Bio-Pur® comfort layer; however, this mattress has an ultra-soft feel, giving side sleepers maximum contouring and pressure relief.

Thanks to the responsive transition layer and the spring coil base, the AS5 Hybrid won’t cause excess sinking, unlike many soft mattresses. The Active Flex transition layer has a slight bounce to lift and align the hips, ensuring the spine doesn’t bow and cause the muscles in the back to clench and tighten.

Beneath the Active Flex layer is a base of individually wrapped springs. These coils move independently, allowing them to contour to each curve of the body. They are each wrapped in a lightweight yet durable material to increase comfort and breathability. The mattress’s perimeter is also reinforced with edge support to reduce motion transfer and make sitting on the edge of the bed more comfortable.

With Amerisleep’s 100-night sleep trial, you can test out any of their mattresses at home for 3 months. This gives sleepers plenty of time to make sure the support of the mattress is right for them.

2. Zoma

Zoma is an innovative online mattress brand, offering sleepers two different models—an all-foam and a hybrid mattress. Both beds feature a medium comfort layer made with their proprietary gel-memory foam. The gel-infusion in this material pulls heat and moisture away from the surface of the bed, so sleepers stay cool and comfortable throughout the night. This mattress is perfect for hot sleepers and those who frequently experience night sweats.

Zoma Warranty

With each mattress, Zoma provides a 10-year warranty covering indentations not associated with improper use or an inadequate foundation. Indents must be visible and greater than .75 inches. Once defects are verified, Zoma will provide a full replacement.

Zoma Mattresses

The gel memory foam comfort layer on each Zoma Mattress features Triangulex™ technology—triangular cutouts placed throughout the foam to keep the joints cushioned and the lumbar spine supported. These cutouts also promote circulation to prevent heat buildup.

Beneath this unique comfort layer, Zoma includes a layer of Reactiv™—a latex-like response foam to prevent over sinking and spinal misalignment. When the joints are protected, and the spine is neutral, muscles can completely relax, making sleep easier to come by.

Zoma’s Hybrid mattress has the same comfort and transition layer as the all-foam Zoma, but with a base of pocketed spring coils. Unlike transitional spring coil beds, which tend to be noisy and stiff, Zoma’s coils move separately from one another, allowing them to compress easily near the joints and provide support along the back. These coils are also quiet and have minimal motion transfer, perfect for couples and light sleepers.

You can take advantage of Zoma’s 100-night sleeper trial and try out either of the mattresses for yourself. If you are not completely happy after a month, Zoma will provide a full refund.

3. Vaya

Vaya produces two mattresses with a medium firmness, perfect for couples with different firmness preferences. Both models are made with Vaya’s hypoallergenic foam, which won’t cause nasal or skin irritation for those with severe allergies. Plus, they offer a generous sleep trial period and warranty.

Vaya Warranty

Vaya’s 10-year warranty covers repairs or a full replacement if the mattress develops sags or indents greater than .75 inches. They will also cover visual defects such as loose threads or cracks in the foam.

Vaya Mattresses

The original Vaya Mattress has a supportive yet soft and inviting comfort layer to promote deep relaxation. Vaya’s foam is produced with eco-friendly methods, making it more breathable and responsive than traditional mattress foams. This foam’s natural elasticity keeps the hips and shoulders from sinking too far into the bed, so the spine remains neutral. The base of the Vaya Mattress features a sturdy support foam to ensure even weight distribution and prevent sagging.

The Vaya Hybrid has the same supportive comfort layer as the original Vaya, but the base is made of pocketed spring coils rather than foam. The bounce of this coil base is perfect for back sleepers and heavier individuals who need the pressure relief of foam. The responsiveness of this base also prevents the uncomfortable sensation of being “stuck” in the mattress. So sleepers can easily change positions throughout the night.

What is a Mattress Warranty?

A mattress warranty is a period of time when the company will repair or replace the mattress if a defect becomes apparent. Warranties are designed to protect the consumer. Therefore, they typically cover major defects that affect the structure of the bed. While most brands are transparent about what their warranty does and does not cover, it is always important to read the fine print. Below, we explain the ins and outs of mattress warranties and what to consider as you shop.

How Long Does a Mattress Warranty Last?

Since most high-quality mattresses last between 8 to 10 years, a 10-year warranty is standard. If you come across a company offering anything shorter, it is best to keep shopping since this is typically a sign of poor quality. Additionally, you may find some brands offer a lifetime warranty. While this may sound appealing to consumers, it doesn’t add any real value because most mattresses are not designed to last a lifetime. The majority of warranty claims after the first 10 years of use are deemed normal wear and tear.

Most warranties over 10 years are prorated; this means the customer is responsible for a portion of the repair or replacement, usually 50 percent, if something goes wrong with the mattress after the first 10 years of use. Considering most mattresses last between 8 and 10 years, a prorated warranty is a great way to extend the life of your bed.

What Does a Mattress Warranty Cover?

While each company has slightly different warranty guidelines, they typically cover premature sagging and indentations since this can affect the mattress’s performance. However, some companies only cover large indentations deeper than 1.5 inches, while other brands cover small sags greater than .75 inches.

The depth of the sag is typically measured by placing a taut string across the mattress’s surface. Then, the space between the string and the bed’s surface is measured to determine how deep the indentation is. Once this is measured, the company will either repair the mattress or provide you with a replacement.

If the mattress has a spring coil base, the warranty will likely cover broken or bent coils or those sticking up into the comfort layer, causing lumps. A good warranty will also cover loose threads in the cover, bunching foam or material, and other visual defects.

What Does a Mattress Warranty Not Cover?

A warranty will not cover damage caused by the customer, such as stains from accidents or spills, tears in the cover caused by moving, or creaks in the foam from folding the mattress. They also will not cover “normal wear and tear.” This term is often used to describe the natural breaking in of a mattress.

Warranties also do not cover comfort issues, such as a mattress feeling too firm or too soft. Therefore, be sure to select a bed with a long sleep trial. A 2 to 3-month trial will give you enough time to test out the bed and make sure it is right for your body type and sleep position. If you are not happy with the mattress, most reputable brands will provide a full refund.

What Can Void a Mattress Warranty?

When bringing home a new mattress, be sure you understand how to care for it properly. Certain actions may inadvertently void your warranty and leave you stuck with a comfortable and unsupportive mattress. The following are some of the most common mistakes that lead to a voided warranty.

• Incorrect foundation/support structure: Your mattress should rest on a flat, supportive surface to ensure sagging does not occur. For example, if slats are spaced too far apart, the mattress can sag. Therefore, most mattress companies will not honor the warranty if the mattress is placed on a slatted foundation with slats spaced more than 3 inches apart or on a box spring.
• Stains: Even if a stain didn’t necessarily cause a specific defect, the presence of stains on the mattress could still avoid a warranty. Water and other liquids can cause the foam to break down, so most companies will not repair or replace those with stains. Therefore, it is important to use a waterproof mattress protector to ensure your warranty remains valid.

• Removing the law tag: Although tags on the side of your mattress can be a nuisance, it is important to leave them in place. Removing the manufacturer’s tag marked “do not remove under penalty of law” can automatically void the warranty because it is proof that you purchased the mattress. Without this tag, the company can not verify who bought the bed, and they will not honor the warranty.
• Buying used or refurbished: If you buy a used or refurbished mattress and you are not the original purchaser, the warranty will become null and void. Even if the mattress is fairly new and still covered by the original warranty, it will automatically become void once it changes ownership.

How to Extend the Life Of Your Mattress

The following tips can help you get the most out of your new mattress and ensure it supports you for many years. These steps will also keep your warranty intact and make sure it is honored if something goes wrong in the future.

• Use a stable foundation: A high-quality mattress foundation will prevent sagging and indentations. Most innerspring mattresses can be paired with a box spring. However, mattresses with foam, such as memory foam, latex, foam, or hybrid mattresses, should rest on a solid surface or slats spaced no more than 3 inches apart. Most companies sell foundations designed specifically for their mattresses, making it easy to purchase the correct one. If you have a bed frame with wide slats, you can place a 1-inch piece of moisture-resistant plywood or a bunkie board between the slats and the mattress.
• Use a waterproof mattress protector: Sometimes, accidents happen, especially if you have children. Having one of the best mattress protectors with a waterproof covering is a great way to safeguard the quality and construction of your mattress.
• Clean and inspect your mattress regularly: Regularly cleaning your mattress and inspecting it for defects will ensure it stays supportive and germ-free. Our guide on how to clean your mattress will walk you through several quick and easy steps.

Frequently Asked Questions

Can a mattress last 20 years?

Typically, mattresses last between 6 to 8 years. However, memory foam mattresses can last 8 to 10 years, while those made with latex foam beds last slightly longer, about 10 to 12 years. Depending on the foam used in the top layer, most hybrid mattresses will last between 8 and 12 years.

How often should you replace your mattress?

On average, most people replace their mattress every 6 to 8 years. If you start to wake up with aches and pains or if it becomes difficult for you to get comfortable on your mattress, it may be time to replace it.

What happens if you tear the tag off a mattress?

The manufacturer’s tag contains vital information that links the sale of the mattress to you. If you need to make a warranty claim, the company will use the information on this tag to verify you are the original purchaser. This tag is typically labeled “do not remove under penalty of law.” If you remove the tag, your warranty may be voided.

How do I know if my mattress is defective?

The best way to tell if a mattress is defective is by visually inspecting the bed. If you notice large indentations or sections of the mattress that sag, it may be a manufacturing defect. Also, look for cracks, divots, or holes in the foam that may lead to larger problems down the line.

Does putting plywood under a mattress help?

Most bed frames have a slatted foundation to support the mattress. However, if the slats are more than 3 inches apart, they may not correctly support all mattress types. If you don’t want to replace your bed frame, a 1-inch piece of moisture resistant foam plywood or a bunkie board can be placed between the slats and the mattress. This layer will prevent sagging and indentations from forming.

Do I need a box spring?

Traditionally, innerspring mattresses are paired with a box spring. Box springs used to house innerspring coils to push against the coils in the mattress for even weight distribution and shock absorption. However, most modern box springs do not have coils, so they offer little support. In fact, most memory foam mattresses should not rest on a box spring because it can sink in the middle.

However, box springs do offer height. If you prefer a higher bed and want to continue using your box spring, you can place a 1-inch piece of plywood between the box spring and the mattress. However, be sure your bed frame can support the weight of a box spring, plywood, and a mattress.

Conclusion

Anytime you invest in a large purchase, such as a mattress, it is important to have a great warranty. Knowing you are covered if anything goes wrong gives you peace of mind and allows you to enjoy your new mattress even more. However, not all warranties are the same. Some are more transparent and offer clear guidelines on what is and is not covered, while others use vague language and try to appeal to consumers with large, unrealistic promises. As you shop, be sure to read the fine print on your warranty so you can understand the specific defects covered and the exact coverage time.
