Purple Restore Hybrid

Our take - The Layla Hybrid 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. It's soft and comfortable, but also supportive like it was contouring my body in all the right places without sinking too much. This hybrid mattress also had very little (if any) motion transfer. I wasn't disturbed or jolted awake when my partner tossed and turned.

Our take - 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, you also want it to have enough give to contour your body and alleviate pressure, which is exactly what The Cocoon offers. If your mattress firmness level is too soft, it can lead to back pain and many restless nights.

Our take - 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 roughly equal parts soft and firm and may work well for most sleepers.

Our take - If you suffer from back pain -- or you don't have any pain and you want to keep it that way -- 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 provides enough support to keep my spine properly aligned, but still felt soft enough to have some give for my pressure points. 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.

Our take - The Purple Restore Hybrid mattress is a dream. 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 Restore Hybrid bed is made from a hyper-elastic polymer grid formation that feels strong and supportive, but somehow still soft and plush. 

Our take - 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. Equally importantly, it's comfortable and supportive too.

When looking for the best full mattress, here are a few things to keep in mind. 

Firmness

The firmness of a mattress is dependent on your body type. If you are petite or an average person, your body will exert less pressure on a mattress, making it feel firmer. If you are a heavier sleeper, a mattress will feel softer. An average sleeper will find a medium firmness to be comfortable.

Support

Especially if you deal with back pain, you want a supportive mattress. A memory foam mattress is generally less supportive than a hybrid mattress that has both foam and coils. Petite and most average-size sleepers will still find memory foam mattresses supportive. If you are a heavier sleeper, opt for a hybrid or an innerspring mattress.

Edge support

The edges around your mattress should also be supportive. That way, you won’t roll off your bed in the middle of the night. You can test edge support by sitting on the edge. If you feel like you're going to slip off, you might want a bed with better edge support.

All of the beds above have been tested by our CNET Sleep editors, but we've also reviewed over 200 other beds. With that being the case, it can be difficult to narrow down the top favorites. 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.

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.

Allswell mattress: Looking for the best value? 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.

Our CNET Sleep editors have spent countless hours testing each mattress on our many best lists. When we test mattresses, we have an established process that assesses key factors like firmness, feel, construction, performance, price, cooling properties and warranty information. We test how strong the edge of the bed is by sitting and lying on the edge. We test motion transfer by rolling across the mattress with a glass of water by the edge. We do this for all beds we test.

CNET editors pick the products and services we write about based on editorial merit. When you buy through our links, we may get a commission.

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. 

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. 

Yes, a full-size mattress is big enough for two average sleepers. The bed might be a little small if one person is taller or a little heavier. Also, if you need space for pets or extra stretching room, a queen-size mattress might be better.

A full mattress is worth considering if you have a smaller space or you're a single person who likes to spread out (since a twin mattress doesn't provide much room). If you're a co-sleeper, you should be able to fit snugly, but a queen mattress would be more suitable.
