Launched in mid-2017, the Tomorrow Sleep mattress is the flagship product for a host of sleep products offered by the mattress giant Serta Simmons.

The Tomorrow Sleep mattress is a hybrid built with a base of innerspring coils topped with foam layers, including memory foam. It is offered in two models -- Medium Soft and Medium Firm -- that have a different composition of the layers above the coils. Both models are 10” tall and have a cover with a phase-change material (PCM) designed to help with temperature regulation.

Customers can choose between two different models that have a different firmness level. The Medium Soft mattress falls as a 4 on the typical firmness scale while the Medium Firm is around a 6.


The Tomorrow Sleep mattress is currently only available for purchase on the company’s website.


The construction of the Tomorrow Sleep mattress is different for each of the two firmness models. Both the Medium Firm and Medium Soft mattresses have a set of 6” foam supports around the outside of the coils designed to improve edge support.

Medium Soft model

  • The top layer is made up of 1” of memory foam with a density of 4.8 PCF and the temperature regulating PCM material.
  • The second layer is 2” of gel-infused polyfoam with a density of 2.5 PCF.
  • The third layer is 6” of pocketed carbon-steel coils
  • The bottom layer is 1” of support polyfoam.

Medium Firm model

  1. The top layer is 1” of memory foam with a density of 3.5 pounds per cubic foot (PCF) and with a phase-change material (PCM).
  2. The second layer is .5” of a gel-infused polyfoam that has a density of 2.5 PCF.
  3. The third layer is 1.5” of another polyfoam that has a density of 2.6 PCF.
  4. Beneath these foam layers is 6” of pocketed carbon-steel innerspring coils.
  5. The bottom layer is 1” of support polyfoam.

Standard shipping with UPS ground is offered free of charge with your purchase, and using this option, the mattress normally will arrive within 3 working days after it is ordered. Shipping is only available to the continental United States. With standard delivery, the mattress is shipped as a “bed-in-a-box,” meaning it is sealed in packaging and delivered straight to your doorstep. After you remove it from the box and plastic, it expands to reach its full size. Ten minutes later, your mattress is ready to sleep on.

Additional Services

Tomorrow Sleep also offers extra delivery services for extra charges. White glove delivery includes bringing the box into your bedroom, unboxing it, unwrapping it, and installing the mattress where you want it to be. This costs $75 and up depending on the delivery location. For $49 more, the company will haul away your old mattress. If you return the mattress, these delivery charges are not refundable.

Sleep Trial

Tomorrow Sleep offers a very generous sleep trial of 365 nights. During this year, you can decide to make a return in which case the company picks up the mattress and refunds your purchase price. The sleep trial requires that you keep the mattress for 30 nights before making a return.


The Tomorrow Sleep mattress comes with a 10-year limited warranty that covers defects in manufacturing. The warranty does not include coverage for transportation costs related to a warranty issue. 

Tomorrow Sleep Mattress Performance

Motion Isolation

Because the comfort layer is made with memory foam, the Tomorrow Sleep mattress generally does well when it comes to isolating motion. Though the bounce from the innerspring coils means that there is still transfer of motion, but it is usually limited enough that it does not pose an issue for most sleepers who share their bed with someone else.

Edge Support

Both Tomorrow Sleep mattresses offer quality edge support thanks to both the innerspring coils and the reinforcement of the edges with foam around those coils. While there will still be some compression of the foam when sitting on the edge of the bed, this mattress outperforms most foam-only mattresses when it comes to edge support.

Heat Retention

Two features of the Tomorrow Sleep mattress help it to keep from sleeping hot. First, the phase-change material in the topmost layer is designed specifically to help with temperature regulation. It works to dissipate heat that comes off of the body, limiting heat retention. Second, the bounce provided by the coils in the support core help hedge against sinking too deeply into the bed, which helps prevent problems related to airflow or overheating.


Typical of most mattresses with a foam component, some light smell is expected when you first open up this mattress, but it is not harmful and should go away within a few hours.


Both of these mattresses are likely to offer at least an average amount of support. The topmost comfort layer of memory foam brings a high level of responsiveness, and this can make sure that each part of the body gets the padding that it needs so that the body is in alignment. The innerspring coils also contribute to this support as encased coils are more responsive than traditional innerspring designs.

The primary risk for support is that the most responsive comfort layer -- the memory foam -- is also relatively thin, especially in comparison to many competitors. This may make the memory foam less supportive, especially for sleepers who weigh over 230 pounds or who have exaggerated pressure points.


In general, memory foam is very conforming to the body. It is one of the main strengths of this material. However, with only 1” of memory foam, some sleepers may find that the overall amount of contouring provided by this mattress may be less than other mattresses with thicker memory foam comfort layers.


Because it has only spent a short time on the market, there is no long-term data about the durability of this mattress. While we expect the mattress to perform well for at least 5-6 years, the fact that it has some slightly lower-density support foams may reduce its overall useful life, especially for people who put a lot of wear-and-tear on their bed.


The bounce and edge support offered by the support core of this mattress can help ensure that there is no serious inhibition of movement on top of the bed. As a result, the Tomorrow Sleep mattress does not pose barriers to sex for the vast majority of people.

What Type of Sleeper is Suited to the Tomorrow Sleep Mattress?

No one mattress is best for everyone, so it’s important to consider what features are most important for you and what kind of mattress is most likely to suit your needs. The robust sleep trial offered by Tomorrow Sleep can provide some comfort in knowing that you’ll have plenty of time to see if this mattress is a good fit for you.

One factor that may help in considering whether this mattress is right for you is your sleeping position.

Side Sleepers: many side sleepers like the hybrid design of this mattress and find that it provides a good blend of both resilience and contouring. However, for sleepers of above-average weight, the thin comfort layer is more likely to pose a problem given the pressure points that side sleepers have at the shoulders and hips.

Back Sleepers: because the coils help to limit the total amount of sink, these mattresses can be excellent for back sleepers who need contouring but who don't want their torso to sink too far into the mattress.

Stomach Sleepers: the Medium Soft version of this mattress is generally going to be too soft for most stomach sleepers, but the Medium Firm may be viable, especially for stomach sleepers who want both bounce and contouring.

Medium Soft
Under 130 lbs 130-230 lbs Above 230 lbs
Side Sleepers Very good Good Fair
Back Sleepers Very good Very good Fair
Stomach Sleepers Good Fair Poor
Medium Firm
Under 130 lbs 130-230 lbs Above 230 lbs
Side Sleepers Good Good Excellent
Back Sleepers Good Very good Good
Stomach Sleepers Good Good Fair

Our Verdict

The Tomorrow Sleep mattress provides a hybrid design with some excellent added features including the bolstered edges and phase-change material. For customers who like the springy feeling of an innerspring but want added contouring, it makes for an intriguing option.

The fact that the mattress comes in two different firmness choices also is a boon for those who want something either a little softer or firmer.

On top of all of this, the extremely customer-friendly sleep trial of a full year can go a long way to alleviating any concerns about winding up stuck with a mattress that you don’t like.
