Full-size mattresses are ideal for single sleepers upgrading from a Twin-size bed for more sleeping space, guest rooms, and couples sharing a smaller bedroom. Here are some things to consider when choosing the best full-size mattress:
- Support and Pressure Relief: You'll want a mattress with the right balance of support and pressure relief for you. To ensure a mattress is suitable for how you sleep, look for a score of at least 7.0 for your weight category and sleeping position.
- Edge Support: Sturdy edges help maximize comfortable sleeping space, which is especially important if you sleep with a partner. To find models with solid sides, look for an edge support score of at least 7.5.
- Cooling: A mattress that dissipates heat efficiently will help keep hot sleepers cool. If feeling overheated prevents you from falling or staying asleep, look for a cooling score of at least 8.0. If you sleep with a partner, look for a higher score of 8.5 if you're concerned about cooling, since sharing a smaller sleeping surface can make you feel warmer.
- Motion Dissipation: Motion dissipation is particularly important for couples. Motion doesn't have to travel as far to bother you on a full-size mattress, so if you sleep lightly, look for a mattress with a score of at least 8.0 for good motion dissipation.
We've tested more than 65 mattresses, and below you'll find our recommendations for the best full mattresses. For more options, check out the best mattresses-in-a-box and the best memory foam mattresses. We also recommend the best Twin XL mattresses.
We've tested over 55 mattresses. We purchase each unit independently from major retailers, just like you, to keep our reviews free of manufacturer influence. Each mattress undergoes the same tests to measure objective data on characteristics like firmness, cooling, and motion isolation, so you can easily compare results. Since we buy all our mattresses, we can tear them down layer by layer and isolate the mechanical properties of every component: quilted tops, foams, coils, and any special materials.

Best Full-Size Mattress
Side Sleeping8.2Back Sleeping7.4Stomach Sleeping7.2Cooling8.2Motion Dissipation8.2Longevity6.8Firmness Level:Medium (44 Pa/mm)See all our test resultsEdge Support:The Helix Midnight Luxe 2025 is the best full-size mattress we've bought and tested. This mattress's versatile performance and fantastic edge support make it a good full-size option for single sleepers and guest rooms. Its soft comfort layers allow deep sinking and create an enveloping feel, while zoned pocket coils help keep your hips in line with the rest of your body. It's also quite bouncy and very responsive, so despite its plush upper layers, you won't feel constricted or tightly hugged. Overall, it's a good option for a range of people, including side and combination sleepers.
Pick if: You want a full-size mattress for yourself or a guest room with sturdy edges and plush pressure relief.
Skip if: You're a heavier back/stomach sleeper and need more support.When we cut open this mattress to analyze its construction, we found its edges are reinforced with stiffer springs, providing fantastic edge support and maximizing comfortable sleeping space. Similarly, we were impressed with the foam quality; this mattress is predominantly made from dense, good-quality foams, which will help it maintain its performance, comfort, and support for longer. It offers great cooling, so it's a suitable option if you sleep hot and you're not sharing with a partner. Similarly, its great motion dissipation performance will help prevent you from feeling smaller movements, like a cat jumping onto the foot of the bed. However, couples sharing a full-size bed may want even stronger cooling and motion dissipation.
While it's decently supportive for most people, average-weight or heavier people might want to add the 'Ergo Align Support Layer', an extra layer of foam in the lumbar area intended to add more support for back or stomach sleeping.

Best Upper Mid-Range Full-Size Mattress
Side Sleeping7.2Back Sleeping7.1Stomach Sleeping7.0Cooling7.3Motion Dissipation8.2Longevity7.6Firmness Level:Medium (47 Pa/mm)See all our test resultsEdge Support:The Big Fig Mattress is a cheaper option you might prefer if you want a very durable full-size mattress. This Medium hybrid has a less enveloping feel and doesn't offer as much pressure relief as the Helix Midnight Luxe 2025, so lighter people may not find it as comfortable. Otherwise, our testing found its balance of support and pressure relief makes it a comfortable option for most side sleepers.
Pick if: Your priorities are durability or edge support.
Skip if: You're a hot sleeper or a lighter side sleeper.It's also much bouncier and more responsive, so you might prefer it if you want a mattress that supports your movements and feels very easy to move around on. It's one of the most durable mattresses we've tested, with four layers of good-quality or high-quality foam, which will help it maintain its feel and support performance for longer. The mattress has excellent edge support, so you can comfortably spread out over the whole sleeping surface, which is especially important in a full-size mattress. It offers great motion isolation overall, so you're unlikely to feel smaller movements like a cat jumping onto the bed. However, bigger movements, like someone getting into bed, can make the mattress wobble for a moment. Plus, its cooling is just decent, so it's not the best full-size mattress for couples.

Best Mid-Range Full-Size Mattress
Side Sleeping7.9Back Sleeping7.7Stomach Sleeping7.6Cooling8.4Motion Dissipation9.0Longevity6.3Firmness Level:Medium (46 Pa/mm)See all our test resultsEdge Support:You might prefer the Tuft and Needle Mint if you're looking for a full-size mattress for you and a partner. This mid-range all-foam mattress isn't as durable as the Big Fig Mattress, but strong support and pressure relief make it more versatile and likely to suit both you and your partner's sleeping styles.
Pick if: You're looking for a full-size bed for you and a partner.
Skip if: You want maximum durability.It also offers outstanding motion dissipation, which is especially important when sharing a relatively small full-size bed. You won't feel most of your partner's movements, and while you might feel bigger moves, like someone getting into bed, you'll only feel motion briefly, and the mattress won't wobble or bounce. The edges are very sturdy, giving you more room to comfortably share without feeling at risk of falling out of bed. Also, when we cut open the mattress and tested the density of the foam layers, we found they're all made of good-quality foam, making it a decently durable mattress that will resist sagging for longer than mattresses that include lower-density foam. It's also cooling enough for most people, although if cooling is a priority for you, you may want even better cooling from a full-size mattress that you're sharing with a partner.

Best Budget Full-Size Mattress
Side Sleeping7.4Back Sleeping7.4Stomach Sleeping7.5Cooling7.9Motion Dissipation8.6Longevity6.7Firmness Level:Medium (42 Pa/mm)See all our test resultsEdge Support:Consider the Casper Cooling Select if you're looking for an inexpensive full-size mattress. This Medium all-foam model available at Costco (U.S.) isn't as cooling as the Tuft and Needle Mint, and it could make you feel overheated if you're a hot sleeper and sleep with a partner. The comfort layers don't allow as much sinking, and as a result, it has worse pressure relief, but you might prefer it if you like sleeping 'on' instead of 'in' your mattress. Overall, its decent pressure relief and good support for most people make it a good budget-friendly option for a range of sleepers.
Pick if: You want a budget-friendly mattress for yourself or a guest room.
Skip if: You sleep hot or want a mattress with an enveloping feel.This mattress offers excellent motion isolation. You'll feel more movements overall versus the Tuft and Needle Mint, but they stay localized, so you mostly feel movements near the source and not all over the mattress. Motion dissipates extremely quickly, so movement doesn't make the mattress wobble or bounce. It has good edge support, too. The edges compress evenly, without forming much of a ramp, so you can sleep near the side without feeling at risk of sliding out of bed. It's also fairly durable, since it only includes good-quality foam. However, it's not as bouncy as the previous pick, which can make it feel a bit sluggish and make movement feel more effortful. That said, the sleeping surface is responsive, so you won't feel tightly hugged.

Best Cheap Full-Size Mattress
Side Sleeping6.7Back Sleeping7.3Stomach Sleeping7.5Cooling8.3Motion Dissipation8.8Longevity6.0Firmness Level:Medium-Firm (54 Pa/mm)See all our test resultsEdge Support:The Allswell Hybrid is worth considering if you're looking for a cheap full-size mattress that performs well. This Medium-Firm mattress isn't as durable as the Casper Cooling Select, but its solid edges and excellent motion dissipation make it a great full-size option. It's just as supportive as the previous pick, and while its fairly firm comfort layers don't allow as much sinking, they mold around you closely, which helps it offer decent pressure relief for most people. It's also bouncy and responsive, so combination sleepers will find it easy to move around on.
Pick if: You're looking for a cheap full-size mattress for you and a partner.
Skip if: You want a durable mattress or you're a lighter side sleeper.We found its edges won't compress much under pressure, so you can comfortably use the entire full-size sleeping surface. Its motion dissipation performance is also amazing, so you'll feel even fewer of your partner's movements, and it's cooling enough for most people. However, it doesn't contain as much good-quality foam as the previous pick and may start to form permanent indentations sooner.

Best Full-Size Mattress For Cooling
Side Sleeping7.1Back Sleeping6.8Stomach Sleeping6.7Cooling9.9Motion Dissipation8.3Longevity7.4Firmness Level:Medium (45 Pa/mm)See all our test resultsEdge Support:If you're looking for a full-size mattress with strong cooling, consider the Purple RestorePlus Hybrid. This Medium mattress isn't as versatile as options like the Helix Midnight Luxe 2025, since it's not comfortable for lighter side sleepers. However, if its particular blend of pressure relief and support works for you, outstanding cooling makes it worth considering for hot sleepers, especially for couples sharing a full-size bed. We measured off-the-charts cooling, both when you first get into bed and all night. This is in part because of its unique grid-shaped comfort layer, which likely helps it dissipate heat, while creating a responsive, contouring sleeping surface that doesn't feel overly enveloping or constricting.
Pick if: Most mattresses make you feel overheated.
Skip if: You're a lighter side sleeper or a heavier back/stomach sleeper.The mattress's great edge support helps make the mattress feel a little bigger, which is another plus for couples looking for a full-size bed. Its motion dissipation performance isn't as impressive as its cooling, but it's still great, so you won't feel every little move your partner makes. Motion is also mostly felt near the source and dissipates quickly. It's also decently durable, since the single foam layer in the mattress is made of good-quality polyfoam that'll help it resist forming permanent impressions and maintain its performance for longer.

Saatva Latex Hybrid:
The Saatva Latex Hybrid is a Firm mattress with a latex comfort layer, making it very durable. It's very cooling and offers balanced support and pressure relief for a range of sleeping positions and body types. However, its motion dissipation is much worse than that of the Helix Midnight Luxe 2025, which will be especially noticeable on a full-size mattress, and makes it not so great for couples.

Sleep On Latex Pure Green Organic (Medium):
The Sleep On Latex Pure Green Organic is a Firm all-foam mattress. It's entirely made of high-quality latex, which makes it unusually durable. It's also impressively supportive overall, making it great for back and stomach sleepers, but unlike the Big Fig Mattress, it offers little pressure relief, so it's only suitable if you prefer sleeping 'on' your mattress and don't sleep on your side.

FAQs
Is a Full-size mattress big enough for two adults?
A full-size mattress is big enough for two adults, but because of the smaller sleeping space, aspects like edge support and motion dissipation are even more important. If you're sharing a Full-size bed with a partner, you'll want sturdy edges so you can comfortably sleep near the side, and strong motion isolation, since being closer to your partner makes movements more noticeable.
Full vs. Queen: who should choose each size?
Full-size mattresses are suitable for single sleepers and couples who want to save money or preserve floor space in a small bedroom. You might prefer a Queen-size bed if you sleep with a partner and want more sleeping space, especially if you're a hot sleeper or easily disturbed by your partner's movements.
Full vs. Twin XL: which is better for one adult?
You might prefer either a Full (54" X 75") or Twin XL (38" X 80") mattress, depending on your needs. Taller adults might appreciate a Twin XL's extra length, while combination sleepers who often change sleeping positions might want the extra width provided by a Full-size mattress. If you're looking for a bed for you and a partner, you'll need a Full-size mattress.
