  • 5-Zoned latex offers you the right amount of pressure relief for specific areas of the body.
  • Mattress is designed to be breathable so sleepers get a cooler sleep.
  • Edge support is lined with high-density foam so sleepers are supported when lying on the edge.

The Saatva HD is our best mattress for a 300-pound person due to its focus on offering support while still allowing you to be cushioned. Its plush top layer is comfortable as well as conforming, allowing sleepers to sink into the supportive, pressure-relieving latex layer below. Not only is the latex layer more supportive and responsive than traditional memory foam, but it also has a unique 5-Zoned support to give ergonomic and targeted support exactly where you need it, which I think heavier sleepers will like.

Another feature I think is great about the Saatva HD is its coil system. It’s built with Lumbar Zone® support, so the coils that are usually underneath the lumbar of the spine are reinforced to be more supportive than the rest of the coils, helping keep the spine aligned. This can make falling asleep, and staying asleep easier for sleepers.

  • Gel memory foam helps keep this mattress cool to the touch for better sleep.
  • TitanFlex™ foam helps give cushioning support to relieve pressure.
  • Encased coils also have a reinforced perimeter, making getting in and out of bed easier.

The Brooklyn Bedding Titan Plus Luxe is our runner-up for the best mattress for a 300-pound person due to its ability to cool, support, and resist impressions over time. The Titan Plus Luxe comes with a layer of gel memory foam in its upper layers, meaning it’s cool-to-the-touch which I think hot sleepers will like. Along with this, the gel foam is firm and resistant to impressions, meaning the mattress will serve sleepers for a longer time.

Another great feature that I like about the Titan Plus Luxe is its price point. You save about $2000 compared to the Saatva HD, while still enjoying almost all the similar features such as pocketed coil support, edge support, and conforming foam. That means you can still enjoy a luxury mattress, while also keeping a budget in mind.

Best Memory Foam Mattress for a 300-Pound Person — Puffy

Puffy Mattress Review


  • Cover is hypoallergenic, which helps even sensitive sleepers rest easier.
  • Memory foam layers are designed to be conforming and pressure relieving for better sleep.
  • Cover is also stain-resistant and can be removed for easy washing, keeping your sleeping space clean.

The Puffy Mattress is our best memory foam mattress for a 300-pound person due to its soft, conforming, and adaptive memory foam layers, giving sleepers that luxury feel while still supporting in all the right places. For sleepers who don’t want coils, like the Saatva HD, the Puffy is an excellent alternative as its all-foam design is able to support most sleepers, and give cushioning pressure relief where sleepers need it most.

On top of this, I’ve tested Puffy’s stain-resistant cover to not only be breathable, but practical when it comes to cleanliness. The cover is easily removed and machine-washable. You also don’t have to worry about layers coming apart when taking off the cover — there is a thin second layer that keeps the mattress layers intact while the cover is being washed.

  • Tencel® cover is cool-to-the-touch and naturally derived.
  • Cushioning Euro pillow top uses gel memory foam for added coolness.
  • Mix of foam and coils keep this mattress conforming yet supportive for an  ‘on-top-of-the-bed’ feel.

The Winkbed Plus is our best hybrid mattress for a 300-pound person due to its excellent combination of memory foam layers and reinforced coils, giving the sleeper all the comfort of slow-adapting memory foam, while supporting the sleeper with responsive coils. I’ve tested Winkbed and found its plush pillow top is an excellent counterbalance to the springy coils beneath, giving sleepers comfort that they can sink into a few inches before hitting the firmer layers below. This is in contrast to Puffy, which is all-foam and doesn’t have the springiness that coils can offer.

Another feature of the Winkbed that I’ve tested and like is the gel-infused memory foam top. I found that I didn’t have issues waking up hot with this mattress, as its cover and gel memory foam does a great job of keeping me cool throughout the night.

  • Bio-Pur® memory foam layers are slow-adapting, helping isolate motion so sleepers are disturbed less in the night.
  • Cover is removable for easy washing and maintenance.
  • Bio-Pur® memory foam is also more responsive than traditional memory foam, making movement in bed easier.

The Amerisleep AS3 is our best motion isolation mattress for a 300-pound person due to its Bio-Pur® memory foam, which from my tests, I found to be more motion absorbing, slow-adapting, yet super responsive. This kind of adaptability helps keep motion from disturbing your partner at night. leading to overall better sleep quality. This is in contrast to the Winkbed, which has an emphasis on strong coils that make the mattress more responsive but do not allow it to absorb motion as much.

On top of this, I tested the AS3’s cover, and I have found its mixture of polyester, spandex, and Celliant makes it stretchable and super responsive. The cover also comes off via zippers for easy washing, which I like as it helps me keep my bed cleaner.

Our Methodology - Why I Picked These Mattresses

The best mattresses for a 300-pound person all have one thing in common: support. Lumbar technology and durable materials such as latex or coils help support the extra weight, making the mattress a good choice for sleepers over 300 pounds.

I reviewed mattresses while keeping this in mind, and examined their layers individually for density, structure, and overall quality. Then, I laid on top of the layers on my back, stomach, and side, judging how well the layers cushioned and supported me. I did a series of compression tests, gauging a mattress’s firmness, and measured compressions to determine the sinkage value. Edge support was also tested, and I measured how much the bed sank from sitting and lying on the side to know if the mattress would be suitable for heavier individuals getting in and out of bed. As I’m 210 pounds, a 100-pound dumbbell was used to gauge how the mattress would behave for someone around 300 pounds. My personal experience testing mattresses, plus years in the mattress field, have helped me choose high-quality mattresses for a 300-pound person, and I will share more methods on finding the right mattress for your home at the end of the article.

How to Choose the Best Mattress for a 300-pound Person?

When choosing the best mattress size for a 300-pound person, it’s important to keep in mind that firmness plays an important role, especially in regard to weight. For example, a medium firmness will feel similar to a light sleeper as a firm does to a heavier sleeper due to the mattresses compressing similarly in regards to the weight. This is why, when choosing the best mattress size for a 300-pound person, it’s essential to stick to the firmer options, and get a mattress that’s as firm as possible. 

Not only does a firm mattress for a 300-pound person help ensure that the sleeper’s spine is aligned for better sleep (which, if it isn’t aligned, can lead to back pain, a leading source of poor sleep quality (1)), but it also ensures the bed will last longer. A stronger core means it can handle being slept on for years to come.

If you need suggestions on mattresses for weight a bit less or more than 300 pounds, I have you covered. For general insight, I’ve written more on how to find some of the best mattresses for heavy people.

When choosing a mattress, the mattress thickness is something that heavier sleepers need to consider, as thickness plays an important role in if a mattress will be able to support you or not.

What Kind of Mattress Does a 300-pound Person Need?

The best kind of mattress a 300-pound person needs is one with a high amount of firmness and a durable support system designed to handle the extra weight. This can come in the shape of latex, high-density foam, or a reinforced coil system. In particular, you will need to look for mattresses that don’t sag.

The best firm mattress for a 300-pound person is usually made with quality and durability in mind. Quality is absolutely a must, which can often be found when mattresses are made in the USA. With a more rigorous manufacturing and QA process, you’re more likely to find a better candidate for a good night’s sleep here.

If you share the bed with a partner, especially one affected by restlessness (2), motion isolation is necessary to get better sleep. Careful consideration is needed, as heavier sleepers require support, which can interfere with a mattress’ ability to absorb motion. That’s why we’ve put together a list of the best mattresses for restless sleepers to make the choice easier.


What Materials are Best for Mattresses for a 300-pound Person?

A firm mattress for a 300-pound person usually contains latex, memory foam, coils, or a mix of these materials. Latex is preferred for its natural responsiveness and durability — it’s able to handle a lot of pressure and weight. High density-foam is a close second, especially coupled with coils. When it comes to the best mattress size for a 300-pound person, coils tend to be a key component for larger mattresses, and for best extra firm mattresses.

Is a Spring or Foam Mattress Better for a 300-Pound Person?

A spring mattress tends to be preferred over foam mattresses for their responsiveness and durability, as reinforced steel can more easily handle weight than foam. Keeping that in mind, if the mattress has a solid core, it can adequately support a 300-pound person even if it’s all-foam.

How Do You Know if Your Mattress is Good for a 300-Pound Person?

The best way to know if your mattress is good for a 300-pound person is to test it with the weight. If your mattress doesn’t sink or sag, and keeps the spine aligned while lying down, it's a great option.


It can be overwhelming to choose the best mattress for a 300-pound person, but as long as you keep in mind that it needs to be as firm as possible, and possibly made up of latex or coils, you will be well in the right direction to choosing the perfect mattress.

Our recommendation is the Saatva HD, as it comes fully equipped with ergonomic support in its 5-Zone Latex and coil layers, ensuring that you and your loved ones are supported exactly where you need it, every night.
