Editor’s Pick

saatva mattress


If you’re on the hunt for a high-quality full size mattress and aren’t sure exactly what you want, the Saatva Classic could be a great choice for you. This innerspring mattress comes in three firmness options: plush soft, luxury firm, and firm; most sleepers should be able to find an option that suits their needs. I’d recommend side sleepers go with the plush soft, back sleepers opt for luxury firm, and stomach sleepers choose firm.

Another great thing about the Saatva Classic is its quality and durability. It has a strong innerspring build that gives it tons of support — anyone worried about sagging will really like this bed. It also has reinforced edges that offer great edge support. You can sleep all the way on the edge of the Saatva without feeling like you’re going to roll off — great news for heavy sleepers and couples, and a big bonus when looking at a smaller mattress size like a full.

The Saatva Classic has a 180-night sleep trial and 15-year warranty.

The Saatva is classic innerspring bed that comes in three firmness options, so almost all sleepers should be able to find a version that suits their needs.

Best for Back Pain

The Casper mattress.


If you find yourself waking up with a sore back every morning, it might be time to invest in a new mattress. The Casper Original mattress is a great bed for back pain because it has zoned support, which means it’s firmer where you need it, like at the lower back, and softer at the feet and shoulders for added cushioning. These differing levels of support are meant to promote a straight spinal alignment, which is one of the best ways to combat and prevent back pain.

I also like the full size Casper because it has a balanced, medium-firm feel that should appeal to most sleepers. It has a more “on top of” than “in” the bed feel, which makes it really easy to move around on — great news for combination sleepers.

The Casper has a 100-night sleep trial and 10-year limited warranty.

Best for Side Sleepers

The Helix Midnight mattress.

Helix Midnight

The Helix Midnight is a hybrid mattress that has a pleasant, medium-soft feel that makes it a great choice for side sleepers. Side sleepers need a bed that they can sink into so that their hips and shoulders stay in a nice alignment and are properly cushioned to help alleviate and prevent pain. 

I also really like the Helix Midnight for couples. Not only does it have low motion transfer (so you’re unlikely to feel your partner tossing and turning at night) but it also has some nice bounce for sex and sturdy edges to help the mattress feel bigger. It also sleeps pretty cool, but if you’re looking for an ultra cooling bed I’d check out the souped-up version, the Helix Midnight Luxe. It has a more breathable cover than the original Helix.

The Helix Midnight has a 100-night sleep trial and 10-year warranty.

Best for Pressure Relief

The Puffy mattress.


If you’re looking for a balanced bed that won’t put undue pressure on any part of your body, then look no further than the Puffy. This bed-in-a-box mattress has a solid, all-foam construction and a top layer of memory foam that’s meant to help soothe aches and pains. It has a medium firmness level that should appeal to a majority of sleepers. 

I also like the Puffy because it sleeps nice and cool. Though memory foam mattresses can tend to trap body heat, the Puffy has an infusion of cooling gel to prevent overheating. Hot sleepers take note!

The Puffy has a 101-night sleep trial and lifetime warranty.

The Puffy is an all-foam, medium-firm mattress that evenly distributes your body weight.

Best for Couples

The DreamCloud mattress.


Though I’d personally recommend couples go with at least a queen size mattress, if you’re set on a full size mattress, you’re going to want one that has sturdy edges, so you can take full advantage of the bed’s surface area. In comes the DreamCloud — this mattress has fantastic edge support, and is a really durable mattress overall. Made with a combination of soft, pressure-relieving foams and sturdy, pocketed coils, this bed strikes a nice balance between comfort and support.

Another reason I like the DreamCloud for couples is because it sleeps super cool. Since two bodies overheat more than one, you’re probably going to want to look for a bed with some cooling tech. The DreamCloud has gel-infusions and airflow-promoting pocketed coils, which really pack in a cooling punch.

The DreamCloud has a 365-night sleep trial and lifetime warranty.

Best for Heavy People

The WinkBed Plus.

WinkBed Plus

Heavier sleepers need a supportive mattress that isn’t going to sag under their weight. The WinkBed Plus is a great option for them, as it is specifically designed for heavier weights. This firm mattress is made with strong, steel coils that provide extra support for larger body types.

The WinkBed Plus is also a great choice for heavy couples. Though it has bouncy support, this pillow top mattress also has great motion isolation, meaning you’re unlikely to feel disturbed by your partner’s tossing and turning. It also sleeps nice and cool, thanks to a breathable cover, naturally cooling latex comfort layer, and airflow-promoting pocketed coils.

The WinkBed Plus has a 120-night trial period and lifetime warranty.

Best Cooling

The GhostBed Flex.

GhostBed Flex

If cooling is your main concern when looking for a new mattress, then the GhostBed Flex could be the right bed for you. Firstly, it has a breathable cover quilted with a special cooling fiber. Then, there’s a layer of gel memory foam for some initial cooling comfort, and a latex-like foam layer below that’s also quite breathable. The bed finishes things off with a layer of breathable pocketed coils. It’s the ultimate recipe for a cooling bed!

Beyond its cooling capabilities, the GhostBed Flex shines as a great mattress for combination sleepers. This medium-firm mattress should feel comfortable in a range of sleep positions throughout the night, and it has some nice bounce, which makes moving around easy.

The GhostBed Flex has a 101-night sleep trial and 25-year warranty.

Best Memory Foam

The Bear mattress in the Sleepopolis studio.


If you’re after a full size bed and love memory foam, then the Bear mattress might be the right pick for you. The Bear is my pick for the best full size memory foam bed because it offers the sought-after qualities of contouring and pressure relief. It has a slightly firmer feel than most memory foam mattresses, which makes it an ideal choice for back sleepers or anyone after a bit more support.

The Bear is also advertised as a great bed for athletes. It has a cover made of Celliant, which some studies show can aid in athletic recovery. Beyond that, its graphite gel-infused memory foam layer offers some nice pressure relief, which can be great for sore joints after a workout. 

The Bear has a 100-night sleep trial and 10-year warranty.

Best for Hip and Shoulder Pain

The front of the Brooklyn Aurora.

Brooklyn Bedding Aurora

Those who suffer from hip and shoulder pain need a soft, pressure-relieving bed that will cushion their pressure points. The Brooklyn Bedding Aurora is a great choice for these sleepers, as it has three layers of foam above its pocketed coil layer, which ensures that sleepers will experience a cloud-like feel.

The Aurora also sleeps super cool. It’s made with a cooling cover and each of its foam layers are made with cooling technology. This is another perk for those who suffer from pain, as they tend to struggle to fall and stay asleep, so they certainly don’t need to be woken up from overheating.

The Aurora has a 120-night sleep trial and 10-year warranty.

Best Budget

The Nectar mattress.


The Nectar is an all-foam mattress that’s both budget-friendly and high-quality. That’s why it consistently makes my list for the best mattress under $1,000. This mattress-in-a-box is made entirely of foam and has a top layer of conforming memory foam. It has a medium-firm feel that should appeal particularly to back sleepers. 

I also think the Nectar is a great mattress for anyone with joint pain or arthritis. Its thick memory foam layer should provide the contouring and cushioning that these sleepers need. It also provides enough support to prevent undue pressure from developing at the joints.

The Nectar has a 365-night sleep trial and forever (lifetime) warranty.

The Nectar is an affordable full size memory foam mattress. It’s a nice choice for back, side, and combination sleepers.

How to Find the Best Full Size Mattress for You

A full size mattress is a great choice for a wide range of sleepers, from kids to single adults. If you’re okay with a tighter squeeze, it can also work just fine for couples, and will run at a much lower price tag than a queen, king, or California king mattress.

However, not every full mattress is going to work for every sleeper. It’s important to know what you’re looking for while shopping. Here are a few of the factors you may want to consider:

Sleeping Position 

What position you sleep in is going to dictate what type of mattress is right for you. For example, side sleepers need a softer bed with contouring, which will help take some of the pressure off their hips and shoulders. Conversely, stomach sleepers need a firm bed with lots of support to keep their hips from sinking out of line with their shoulders. Back sleepers should opt for a medium-firm mattress that balances pressure relief and support. Finally, combination sleepers need a medium-firm mattress that has enough bounce to make switching positions a breeze.

Firmness Level 

Mattress firmness is measured on a 1-10 scale, where 1 is the softest and 10 is the firmest. Your preferred sleeping position is going to dictate which firmness level is best for you, but it also comes down to personal preference. If you like the feel of a firmer bed, but you’re a side sleeper, then a firmer memory foam bed could work for you, as long as it provides enough contouring. Most sleepers do best on a medium-firm bed in the 6-7 range.


It’s a good idea to have a bit of knowledge of a bed’s composition before you go shopping. Mattresses can be made of foam, innerspring coils, latex, or a combination of materials. Those made with a combination of materials are called hybrid mattresses. Latex mattresses are great choices for green-shoppers, since latex is a natural material. Innerspring beds are the most traditional type of mattress, and can appeal to seniors and those who need added support. Foam beds are typically cheaper, and I’d recommend looking for the words CertiPUR-US® Certified when shopping for a foam bed to ensure the foam is free of harmful chemicals and pollutants. Finally, you’ll also want to consider what your mattress cover is made of — from organic cotton to polyester, there’s a whole range of fabrics you might find in a cover.

Pressure/Pain Relief

If you suffer from any kind of pain, it’s very important to find a mattress that offers good pressure relief. That means the bed will evenly distribute your body weight, and prevent too much pressure from developing in one area. The best mattresses for pressure relief tend to be memory foam mattresses, which contour around joints, which helps to evenly distribute weight.


Of course, you’ll also want to consider price. Most high-quality full mattresses cost at least $800. Though a mattress can seem like a big investment, you can’t put a price on quality sleep that’ll keep you feeling rested and refreshed each day. If you’re after a deal, I’d recommend shopping around the holidays, as brands tend to run sales around those times. I’d also check out our mattress coupons and promo codes for even more savings.


If you tend to sleep hot, a cooling mattress could be a great investment. Typically, hybrid or innerspring beds are going to sleep cooler than an all-foam mattress, since they allow added airflow. However, some all-foam beds manage to sleep cool, thanks to cooling technology. When looking at mattresses made with foam, I’d keep an eye out for words like “copper-infused,” “graphite-infused,” or “gel-memory foam.” Latex foam is also naturally cooling. Lastly, a cover can make all the difference: those made with organic cotton or Phase Change Material, a fabric that actively works to dissipate body heat, are the best choices.


Contouring is particularly important for side sleepers. That’s because they’ll want their mattress to support their hips and shoulders and provide contouring at their midsection. Memory foam mattresses offer the most contouring, but poly foam and latex foam also offer a bit. Back sleepers might also want to look for a bed with some contouring, which can help support the lower back.

Motion Transfer

Motion transfer refers to how much movement is detectable from one side of the mattress to the other. A mattress with low motion transfer is going to be a better choice for couples, who won’t want to feel their partner’s every movement throughout the night. Memory foam is great at absorbing motion, whereas coils typically transfer motion. If you’re worried about motion transfer, I’d recommend a bed with a thick top layer of foam.

Edge Support

Edge support refers to how well a mattress holds up on the edges as compared to the center. Some beds tend to be less supportive on the edges, which is something couples and larger people should look out for. I’d recommend seeing if the brand mentions edge support or reinforced edges on their site.


Most online mattress brands these days sell bed-in-a-box mattresses, which ship compressed in a box. You’ll have to unbox these beds at home (I’d recommend doing so in the room you plan to use the mattress in). However, if you’d prefer to have someone set up your mattress for you, many companies offer white glove delivery, which means someone will come to your home, unbox your mattress, and place it where you’d like it.

Who Should Buy A Full Size Mattress

A full size mattress can work for almost anybody, but I think they’re particularly suited to kids, teens, and single adults. They’re also a great choice for a guest room. They can be a great option for kids and teens who are still growing, or just want some added bedspace. Additionally, most single adults will have plenty of room on a full size bed, and it takes up less floor space than a queen or king. They’re also a more economical choice, making them a good option for a guest room, if you have one.

What’s the Difference Between a Full Size and Queen Size Mattress?

A full size mattress is 54 x 75 inches, whereas a queen size is 60 x 80 inches. You may think a few inches can’t make that much of a difference, but if you sleep with a partner, it may actually be the deciding factor in morning arguments about sleeping on top of one another. Generally, full size mattresses are best for solo sleepers.

Not only is a full size mattress a few inches smaller, it’s generally a few pounds lighter. This means they can be easier to carry up to apartments or into guest rooms. Full size mattresses can weigh anywhere from 50 to 100 lb.

Aside from size and weight, one main difference between a full and queen mattress is price. A full mattress (also known as a double) is going to be a few hundred dollars cheaper than a queen size mattress. If you are okay with having a little less bedspace, you can save quite a bit purchasing a full size mattress over a queen size bed!
