We’ll also provide pros and cons for each bed so you can choose the right one for you.

Top 07 Most Comfortable Mattress Reviews

01. Snuggle-Pedic Brand Original Ultra-Luxury Hybrid Mattress

Check Price On amazon

This mattress is available in sizes ranging from twin to king. The company is unusual for offering twin XL, full and California king models. We’re recommending the ten inch thick king mattress. It is a hybrid mattress that’s just as comfortable for side sleepers as stomach and back sleepers. It has decent pressure relief.

The bed is made from CertiPUR certified memory foam. That means that the foam doesn’t contain heavy metals like mercury or toxic chemicals like formaldehyde. It gets points for having very little odor.

The bed has some cooling gel mixed into the memory foam. It also has a fair bit of breathability. You’re not going to overheat in this bed.

It inflates to full size fast. The bed is typically true to size, but it may expand to a full inch wider than the expected dimensions. This may cause issues if you have a tight bedframe.

It is firmer than advertised, and that causes problem for people who wanted a medium-firm or soft mattress.

The foam wears down quickly. You could get low spots in just a few weeks, if you’re a heavy side sleeper. This will undermine its support, too, if you’re a side sleeper. You can’t flip it like a standard box spring bed to even it out.


  •  Available in a wide range of sizes
  •  Little to no smell
  •  Nontoxic memory foam
  •  Excellent heat dissipation


  •  Short functional life
  •  Not always true to advertised dimensions

02. Sealy Branded 12-Inch Hybrid Bed in a Box, Medium Firm

Check Price On amazon

This mattress is available in sizes from twin to king. It is available in ten and twelve inch versions. We’re recommending the twelve inch thick mattress. It is more comfortable thanks to the thicker memory foam layer. This is a hybrid mattress, so it has roughly eight inches of metal springs underneath the memory foam.

It doesn’t just have better than average support if you’re a stomach or back sleepers. This mattress has good edge support. You won’t slide off the side of the bed if you sit there. However, you may be able to see the coils through the thin mattress cover. This is more of a cosmetic issue.

One point in favor of this hybrid mattress is that it ships as a bed in a box. It takes about 24 hours to fully expand. That’s faster than average. The foam doesn’t have much of an odor. The mattress itself is relatively lightweight.

The foam is relatively thin. If this doesn’t expand or wears down, you’re lying almost directly on top of the firm coils. We don’t recommend this bed if pressure points are a problem for you. You may sink through the foam and hit the firm coils if you’re a side sleeper, too. The coils themselves are medium-firm.

It isn’t Sealy quality because it isn’t actually made by Sealy. For example, you can get variations in the firmness of the springs. Some people have complained because they can’t return the mattress to Sealy or simply because it was false advertising. It would be frustrating to pay a premium price for a product that wasn’t made by that company.

The memory foam layer doesn’t do anything to dissipate body heat. This bed is not a good choice if you don’t want to deal with heat retention. That may not be an issue if you live in a cold climate or don’t sleep with the covers on.


  •  Bed in a box
  •  Good overall support
  •  Lightweight


  •  Not actually made by Sealy
  •  Prone to cause pressure points
  •  Heat retention

03. Nod Hybrid by Tuft and Needle, Adaptive Foam


Check Price On amazon

Tuft and Needle tries to make universal mattresses. Their company was started before bed in a box firms showed up, but they offer mattresses you can order online.

This mattress is more expensive than average. But you get an incredibly plush surface and supportive innerspring mattress in the process. This bed is available in sizes from twin through king. We’re recommending the standard king sized bed. There is a California king version available.

The bed is only available in a ten inch thick version. The mattress has a six inch layer of pocket coils, an inch of base foam, and three more inches of memory foam. The middle inch of memory foam is slow recovery foam. That limits motion transfer on the memory foam layer. The entire mattress is covered in a ventilated fabric that helps the bed to breathe. The bed typically expands to full size within three days.

This hybrid mattress is softer than average. It isn’t just the plush bed surface but the surface layers of foam with a lot of give. The springs underneath are relatively firm. We’ll recommend this bed for back or stomach sleepers but not side sleepers.

Tuft and Needle mattresses are somewhat more durable than average. It isn’t uncommon for the hybrid mattress to last five or six years. Support may deteriorate with time and load. This means the mattress will last longer if you are heavy, a side sleeper or a couple sleeps side by side on this bed. Nod offers a limited warranty, but it is truly limited.

This bed is unusual for the springs sometimes popping and otherwise making noise while the mattress is expanding. However, this doesn’t affect your quality of sleep once it has expanded. And it is typically fully expanded within three days.

The bed has a modest odor. It can take several weeks to go away altogether.


  •  Limits motion transfer
  •  Relatively supportive


  •  Not good for side sleepers
  •  Odor

04. Signature Sleep Brand Contour Hybrid, 12 Inch Independently Encased Coils and Memory Foam


Check Price On amazon

This is a true hybrid mattress. It has a thick layer of metal coils, each encased in material. This limits motion transfer. On top of this are two layers of memory foam. One layer of memory foam is contoured, creating enhanced air flow within the mattress.

The surface layer of memory foam is relatively soft. We’re recommending the 12 inch thick bed because it offers the most support. This bed is available in full, queen and king sizes. This bed tends to be true to size.

The bed has a polyester and rayon mattress cover. This is not removable, so it certainly can’t be washed in the washing machine. However, this cover makes it easier to spot clean stains on the surface of the bed than a pure memory foam bed.

The bed has the typical smell of a memory foam bed. The odor can take up to a week to dissipate.

The bed has moderate to low support. The support is greatest in the middle of the bed and falls of as you move to the edge. This is much worse than most hybrid beds that only lack edge support. It will cave if you’re heavier than average, a side sleeper or there are two of you sleeping side by side. It may actually dip on the sides of the bed.


  • More easily cleaned than pure memory foam beds
  • Decent support
  • Limited motion transfer


  •  Not recommended for side sleepers or couples sleeping side by side
  •  No side or edge support

05. Leesa in a Box Mattress, Studio Queen, Gray & White


Check Price On amazon

Leesa was one of the first major bed in a box brands. They kept costs low by staying out of the retail stores. While their first beds were not much better than futon mattresses delivered to your door, the Leesa Studio mattress is far better. It is a hybrid mattress with three different layers of foam but no metal coils.

The top layer helps to dissipate body heat while the middle layer relieves pressure points. The core is a firm memory foam layer. That makes the bed almost as supportive as a hybrid mattress with metal coils but much lighter.

It is much more flexible than true hybrid beds, so it is compatible with adjustable beds. You can even bend it if you need to move it.

The Leesa Studio mattress is available in twin, twin XL, full, queen, king and California king versions. We’re recommending the queen sized bed because it is large enough for most individuals and couples. It lasts one to two years of regular use, so it has average durability.

This bed comes with a machine washable bed cover. That only adds to the breathability of the bed. However, the bed will retain some heat. It isn’t as cool as some of the other memory foam beds on the market.

The bed itself is described as medium-firm. The problem is that it is more like medium-soft. That causes problems for side sleepers and those with back pain who need a moderately firm to firm bed.

It has a similar smell to other memory foam beds. Unlike other beds, it can take a long time to dissipate. This is actually made worse by the protective cover on the bed.


  •  Comes with a washable bed cover
  •  Retains its flexibility


  •  Softer than advertised
  •  Moderately hot

06. Classic Brands Model Cool Gel 1.0 Ultimate Gel Memory Foam Mattress


Check Price On amazon

We recommend the Cool Gel 1.0 because it is cheaper than the model 2.0 but has similar performance. That makes this bed the better overall value. You can get a brand new king sized mattress with extra pillows for the cost of a smaller, newer model bed. We’re recommending the king sized bed, though it is available in twin through California king sizes. It is only available as a 14 inch thick mattress.

You can buy this bed with an adjustable or platform base. We don’t recommend using this bed on a bed frame with widely spaced slats. It has little internal support. In fact, you may sink right into it. This is a plus for some but causes problems for side sleepers and heavy users.

This may be a plus for those who want to be snug in their bed or need to have total relieve from pressure points. If you’re a back or stomach sleepers who can’t stand the pressure points caused by springs, this may be the most comfortable mattress.

This bed has a memory foam odor that lasts for weeks. However, it isn’t bad, just noticeable.

The bed does not always fully inflate. When that happens, it won’t be easy to sleep on. It takes several days to fully inflate. You may need to wait two to three days before being able to sleep on it.


  •  Great value
  •  Can buy a compatible bed frame with it


  •  Odor
  •  Little support

07. Live & Sleep Brand Classic King Size Mattress – Memory Foam Mattress


Check Price On amazon

Live & Sleep Brand is a newcomer to the bed in a box market. They have rolled out a luxury bed they say is the most comfortable mattress on the market. This bed is available from twin through king sizes. We’re recommending the medium firm king sized mattress.

The memory foam is Certi-pur certified, and it doesn’t really have an odor. However, the foam is not as good as traditional memory foam. For example, it doesn’t tend to hold its shape. It springs up like regular packing foam. Underneath that surface layer is a very firm layer.

The foam layers end up only softening the firm inner layer. That creates a weird mix of soft and firm that is not the gentle support people with back pain need. Even average sized adults may sink through the foam to the box spring. This can make it hard to change position once you’ve gotten in bed. The bed starts sagging after a year of heavy use, but that’s not uncommon for bed in a box products.

The bed is so soft and pliable that it cannot be used on a traditional bed frame. It either needs to be on a foundation or the floor. The corners are so soft it can be hard to get sheets to stay in place.


  •  No smell
  •  Certipur certified foam


  •  Doesn’t behave like traditional memory foam material
  •  No real support
