Best mattresses with a lifetime warranty in 2023

The Puffy is my Editor's Choice for the best mattress with a lifetime warranty due to its cradling layers, great motion isolation, and strong core. I’ve tested Puffy and found its Cooling Cloud Foam layer to be adequately conforming while on my side, allowing me to sink into the layers comfortably without losing any spinal support. Shoulders and hips tend to be sorest the quickest on mattresses that don’t have good cradling, so my high level of comfort on the Puffy marks this as a good choice for side sleepers. I also tested Puffy for its motion isolation, and found that motion only travels moderately across the bed, meaning your partner should experience menial disturbances while co-sleeping. This contrasts with the Saatva Classic, a hybrid with more noticeable motion transfer.

Another feature I tested with Puffy is its foam core, which I found held me up fairly easily, making Puffy a good choice for lightweight and average-weight sleepers who want a comfortable bed that will support them night after night.

The Puffy also offers a comprehensive lifetime warranty, covering most basic defects and replacing your mattress free of charge in case of these defects. For example, the company will replace a mattress with impressions greater than 1.5 inches that aren’t from using an incompatible bed frame or misusing the mattress.

The Saatva Classic is my best mattress for back sleepers who want to enjoy the best mattress warranty. It comes with patented lumbar technology, a luxurious design that feels as good as it looks, and a reinforced edge. Saatva is unique compared to Nectar or WinkBed, as Saatva has dedicated zones within the center third of the mattress that helps support the spine. A firm foam layer, along with stronger coils, means you can lie on your back without worrying about poor posture — the lumbar zone ensures your back muscles are tension free. Along with that, Saatva’s pillow top provides the necessary contouring that a luxurious mattress should provide, plus it looks impressive, which I think can elevate the look of any room.

Saatva also has good durability on its edges. Mattresses are sometimes known to sag along the perimeter from the full weight of getting in and out. Saatva counters this with a dedicated high-density foam perimeter, which increases the mattress's durability by at least a few years. If the mattress’s overall shape has better durability, your investment lasts longer.

Saatva offers a ‘Friends for Life’ warranty, which means they’ll cover defects based on how many years old the mattress is. For mattresses experiencing defects under 2 years of age, the company will replace it at no additional cost. For mattresses 3 years and older, Saatva will repair and re-cover them with only a $149 processing fee.

Our methodology - Why I Picked These Mattresses

The best mattresses with a lifetime warranty are typically made of high-quality materials meant to last, such as thick layers of memory foam, a sturdy core or innerspring system, along with a durable cover meant to feel comfortable as well as be wear-resistant. There are also not many companies that offer a lifetime warranty, so careful selection had to be made from only a handful of choices.

While testing these mattresses, I kept these points in mind, especially when stripping away the cover and checking out each mattress layer individually. Firmness tests were done by hand and by lying down in different sleeping positions, gauging how well the layers could provide comfort and support. Motion isolation was gauged with further compression tests on one side, and a glass of water on the other, judging how much the water moved based on each compression. I also tested sinkage and pressure relief by measuring compressions on upper and lower body parts. I will share below more methodology tips on choosing the right one for you.

How to Choose the Best Mattresses with a Lifetime Warranty?

To choose a mattress with the best warranty, you will want to make sure the manufacturer explicitly states their mattress comes with a lifetime warranty, and that the mattress in question is made of high-quality material, such as mattresses that don’t sag due to strong cores, to reflect its warranty.

A surefire way to ensure the mattress is high-quality and can make good on its lifetime warranty, is if it’s made locally. I find that mattresses made in the USA have stricter standards than those produced in other countries, such as China, meaning they’re guaranteed to be counted among mattresses without fiberglass or other harmful, low-grade components, such as low-density foam. Low-density foam can be fast-adapting, but loses its integrity quickly after a short time, and often never comes with a lifetime warranty.

Along with having a lifetime warranty, it’s essential to remember that firmness plays a crucial role in how comfortable your nights will be. According to studies, medium-firm mattresses tended to perform better for people in reducing pain and helping them achieve better sleep (1). This is crucial, as better sleep is linked to better health overall (2).

What Are Important Factors to Consider When Choosing a Mattress with a Lifetime Warranty?

Other important factors to consider when choosing a mattress with the best warranty are its durability, its ability to isolate motion, and any support features for the spine. 

It goes without question that a mattress with a lifetime warranty can be counted among some of the most durable mattresses. This is because, most of the time, their cores are built to last for years, using either high-density foam, or innerspring coils.

Restless partners should keep an eye out for motion isolation mattresses, with enough cushioning layers to absorb motion so it doesn’t travel across the bed. This helps both partners get better, less disturbed sleep. Not only does it muffle movement, but the conforming layers also help the mattress feel more comfortable. Motion isolation technology is typically made of high-grade memory foam designed to last a long time, and is a hallmark of what a good mattress is made of.

Dedicated spinal support is also a good feature to look for, such as individually pocketed coils that react to weight more in heavier areas, such as the thighs, or lumbar technology that gives more strength to the center third of the mattress so your hips are always supported. Not only does spinal support technology help your back stay straight and tension-free, but it also means the mattress will last longer due to being able to hold more weight.

Where is the Best Place to Find Great Mattresses with a Lifetime Warranty?

A great place to find the best mattress warranty online would be Reddit. In-person, some of the greatest places to find high-quality mattresses with a lifetime warranty would be 5-star hotel chains and guest rooms at AirBnB.

Reddit is known as one of the most reliable sources of person-to-person information, so it’s no wonder that searches for some of the best mattresses on Reddit can typically mean the mattress is well-made and has a long, if not entire lifetime, warranty. Users who either have the mattress in question or know a lot about it can give insight into which mattresses are better.

In-person, some of the best places to find inspiration for your next lifetime warranty mattress could happen while staying overnight at a hotel or AirBnB. Hotel chains have done extensive research into which mattresses will feel the most comfortable, last the longest, and come at the lowest price — AirBnb’s are no different. So asking a hotel what mattress they use in your suite, or a homeowner what mattress they use for your guest room can help you save a lot of time deciding what works best for you.
