If you haven't been getting restful sleep that leaves you feeling refreshed in the morning, it may be time to invest in a brand new mattress. Fortunately, there are a lot of great affordable mattress options online, and you can instantly compare tons of different types and prices. Going for a full over a King or Queen not only saves you money, generally speaking, but it can save a lot of space, too. The best full mattress options will offer proper support, regardless of whether you find yourself needing something a bit more soft or firm. Plus, most online mattress retailers will offer some kind of return policy, just in case.
Even with satisfaction guarantees, you still want to choose a good full-size mattress right out of the gate. You'll want to consider things like mattress construction, mattress type, pressure relief, motion isolation and your personal preferences. Are you looking for a foam mattress, an innerspring mattress or a hybrid mattress (innerspring with a foam layer)? Do you sleep on your back or are you primarily a stomach sleeper? Do you prefer a soft mattress, a firm mattress or a medium-firm mattress? It's a lot to wade through.
I already did most of the work for you by rounding up six of the best full-size mattresses below. And, once you find the mattress of your dreams, don't forget to also invest in a good bed frame, mattress protector, box spring, pillows and sheets to maximize your good night's sleep.

Flippable hybrid mattress
Firm: 5 or medium | Soft: 3 or medium-soft
10-year limited warranty
The Layla Hybrid really has it all. This mattress type is constructed of several layers, including a gel memory foam, airflow support form and individually wrapped pocketed coils that add extra support and just enough bounce. The mattress felt soft and comfortable, but also supportive, like it was contouring my body in all of the right places, without sinking too much.
This hybrid mattress also had very little -- if any -- motion transfer, which is high on my list of mattress must-haves. I wasn't disturbed or jolted awake when my partner tossed and turned, or left the bed to use the restroom in the middle of the night.
Plus, the middle layer of the Layla Hybrid is made from a copper-infused memory foam, which is designed to absorb and disperse heat, so that you stay cool while you sleep. So unlike other memory foam mattress options that can get hot and stuffy, this one stayed fairly cool, even in the hotter summer months. The copper is also antimicrobial, so it fights off bacteria and other icky things that can build up in the mattress over time.
One of the biggest things that sets the Layla Hybrid apart, though, is the fact that it's a flippable full-size mattress. And not only that, one side of the mattress is soft and the other side is firm, so you can change your sleeping experience every so often or test out both sides of mattress firmness to find out which one is right for you.

Cooling Memory foam mattress
Medium to medium-firm or 6
The Cocoon by Sealy Chill Memory Foam mattress is the perfect marriage of softness and the right amount of mattress firmness support. While having some firmness level is important -- if your mattress firmness level is too soft it can lead to back pain and many restless nights -- you also want it to have enough give to contour your body and alleviate pressure. And that's exactly what you'll find here.
This mattress type is made with a specialized memory foam, called Perfect Fit memory foam, that's designed to adapt to your body almost immediately. Underneath the Perfect Fit layer lies another layer of responsive comfort foam that prevents your body from sagging into the mattress, but also adds some extra cushioning. Not only did the Chill Memory Foam mattress immediately feel comfortable, it also provided excellent pressure relief so I really felt like it took the weight of the day off my body.
It also has a stretch-knit cover that's designed to pull heat away from your body so you don't sleep too hot. Even with a down comforter, I stayed cozy and comfortable.
Poly foam hybrid mattress
5 or medium
15-year limited warranty
The Helix Midnight Luxe is an excellent mattress for when you're not really sure what you want -- or which type of mattress is best for you. When it comes to firmness, this mattress is rated a 4 to 7 out of 10, which means that its firmness level is equal parts soft and firm and can please almost everybody.
A true hybrid mattress, the Helix Midnight Luxe is made from a combination of high-density memory foam, gel visco and pocketed coils. This combination provided excellent lumbar support and relief from aches and pains that I had been dealing with from other mattresses. And it was equally comfortable whether I was sleeping on my side or back, something that can be difficult to find.
The Helix Midnight Luxe also felt plusher than other bed-in-a-box type mattresses. It has a breathable premium quilted top that provides an additional comfort layer of cushioning that feels more reminiscent of a traditional mattress, but without any of the motion transfer. Read more in our full Helix mattress review.
Memory foam hybrid
7 or Medium-firm
20-year prorated warranty
If you suffer from back pain -- or you don't have any pain and you want to keep it that away -- the Amerisleep AS2 Hybrid is an excellent option for you. It's made with a specialized layer of proprietary memory foam, called Bio-Pur, that contours your body and offers pressure relief for your back, hips and shoulders. It has a medium-firm mattress feel that provided enough support to keep my spine properly aligned, but still felt soft enough to have some give for my pressure points. However, I'd mostly recommend this bed to combo, back, and or stomach sleepers because it may not be soft enough for side sleepers in the long-run.
One of my favorite things about this foam mattress, though, was the better response time (compared to traditional memory foam mattresses). When you move around at night or change positions, it takes all foam mattresses some time to adjust. This lagging can lead to interrupted sleep, as it takes some time to get comfortable again. But the Bio-Pur foam responded to movement almost immediately, so I was able to readjust and fall back asleep ASAP.
The Bio-Pur memory foam is also designed to be more airy and breathable than denser memory foams, so the mattress doesn't trap heat at all. I never woke up too hot and sweaty, even in the warmer months. Read more in our full Amerisleep mattress review.
6 or medium to medium-firm
10-year limited warranty
The Purple Hybrid Premier 4 is a dream (pun intended). With its proprietary Purple Grid, it's different from any other mattress I've tried -- in all the best ways. Unlike memory foam, which is the foundation of many of these direct-to-your-door mattresses, the Purple Hybrid Premier 4 is made from a hyper-elastic polymer grid formation that feels strong and supportive, but somehow still soft and plush.
The grid gives way to your body, expertly contouring and alleviating pressure where you need it most, like it was made just for you. I immediately felt weightless, almost like I was floating on this full-size mattress. This Purple mattress also felt bouncier than the others, but it was still able to provide motion isolation and prevent motion transfer.
While it's comfortable in all positions, this Purple mattress is especially great for stomach sleepers since it has enough give to make sure your neck and spine stay aligned. Read more in our full Purple Hybrid mattress review.
7 or medium-firm with the pillow top (9 or firm without)
25-year limited warranty
If you're looking for a comfortable full-size mattress minus any potentially harmful chemicals, the Avocado Green is the mattress brand for you. It's constructed of cotton, wool and natural latex (or you can opt for the vegan mattress, which is the same sans wool) -- which is the safest combination recommended by the Environmental Working Group. This Avocado Green mattress is also free of polyester, polyurethane foam and fire retardants. But equally importantly, it's comfortable and supportive too.
My first impression was that this full-size mattress was too firm, but after a few days, my body adjusted and I was able to settle in. The natural latex mattress started to conform to my body and I felt comfortable and supported. The Avocado Green had just the right amount of give to provide pressure relief, but not so much that I felt like I was sinking into it. It also had a quick response time, so when I changed positions, it re-adapted right away.
One note: My Avocado Green mattress came with the optional permanently affixed pillow top (which costs an additional $400 for a full size), so I can't judge the mattress without it. But I will say that the pillow top added a layer of plushness that I think is worth it. Read more in our full Avocado mattress review.
Poly foam mattress
6 out of 10 or medium
10-year limited warranty
The Casper mattress is one of the most popular bed-in-a-box mattresses, and for good reason. It's a simple, accommodating foam mattress that feels like a giant marshmallow. It doesn't use traditional memory foam, so it's much easier to switch positions on and it bounces back quickly when pressure is removed.
The Original Casper mattress has three layers, the center of which is made with a zoned support design to provide targeted support and pressure relief where you need it most. I'd rate it around a medium on the firmness scale, making it suitable for all sleeping positions from side, back, stomach and combination. For a safe pick that many people find to be comfortable, go for the Casper. Though, the hybrid model is going to be more supportive and durable for people who weigh over 230 pounds.
Other mattresses we've tested
All of the beds above have been tested by our CNET Sleep editors, but they've also been under the covers of over 100 more beds. With that being the case, it can be difficult to narrow down their top favorites. As such, the beds below are other mattresses we've tested that are also worth considering in your search for a new mattress.
Puffy Lux mattress: Side sleepers would also really enjoy the thick and luxurious Puffy Lux mattress. It's just as comfortable as it looks and its cloud logo is a good indication of what you're getting yourself into. It's soft and pressure-relieving as it gently wraps around the curves of your body. The main comfort foam is memory foam, but it's more light and airy than it is dense. I'd rate this mattress around a 4 out of 10 on the firmness scale or a medium-soft, so it's mostly for people who favor their side.
Allswell mattress: Looking for the best bang for your buck? The Allswell mattress is the bed-in-a-box model from Walmart, and in true Walmart fashion, it's extremely wallet-friendly. It'll cost less than most regular foam mattresses, which is rare since hybrid beds are known to be more expensive. It's a little on the firmer side, around a 6 out of 10 on the firmness scale or a medium-firm.
Tuft & Needle mattress: The Tuft and Needle bed is a simple, two-layer foam mattress without any special bells and whistles. I think it's a great mattress for kids, teenagers, your kid going off to college or a money-saving individual. It's pretty wallet-friendly, and it's arguably just as popular as the Casper mattress. It has a similar neutral-foam feel that most people find comfortable, like most people find puppies cute and pizza delicious.

A premium full-size mattress will range around $700 to $1,400, but there are plenty of options under $1,000 like Casper or Tuft and Needle. Full-size beds are more affordable than queen or king size mattresses, but are still suitable for couples who want to share a bed.
What are the dimensions of a full-size mattress?
A full-size mattress measures out to 54 inches wide and 74 inches long, which is 4.5 feet wide and 6.25 feet long.
