Tomorrow Sleep, a brand that is part of the large mattress maker Serta Simmons, offers a hybrid mattress with an innerspring support core and a memory foam comfort layer.

Some of the key strengths of the Tomorrow Sleep mattress include:

  • Year-long sleep trial: the company allows you to try out the mattress for a full year with the option to return it for a full refund. This sleep trial far outpaces the standard offering for most mattresses sold online.
  • Competitive pricing for hybrid design: because Tomorrow Sleep is part of a large mattress manufacturing company, they do not have to outsource the production and design, allowing them to offer this mattress at a competitive price relative to other hybrids on the market.

Potential drawbacks for the Tomorrow Sleep mattress include:

  • Thin memory foam layers: both of the models from Tomorrow Sleep have only a 1” thick layer of memory foam in the comfort layer. While this can help to offer contouring and support, we usually like to see a thicker topmost foam layer to help capture the benefits of pressure point relief from memory foam.
  • Short track record for this mattress: even though Serta Simmons has a long track record in the mattress industry, these models have been on the market for only about a year, which limits the amount of detail we have about their performance and durability over an extended period of time.

Tomorrow Sleep also offers a number of other bedding products, including a sleep-tracking monitor, an adjustable base, sheets, pillows, and more. While this review focuses specifically on the mattress, many customers may be interested in combining some of these different products as part of the company’s broader “sleep system.”

About the Tomorrow Sleep Mattress

Tomorrow Sleep Mattress Specifications

Both the Medium Firm and Medium Soft mattresses from Tomorrow Sleep include the same innerspring support core. However, each has a different design for the comfort layer. You can read more about the layering of each mattress below.

Medium Firm Mattress

Top: 1” memory foam with a density of 3.5 PCF and phase change material (PCM)
Second: .5” of gel-infused polyfoam with a density of 2.5 PCF
Third: 1.5” of polyfoam with a density of 2.6 PCF
Fourth: 6” pocketed carbon-steel coils
Fifth: 1” support foam

Medium Soft Mattress

Top: 1” memory foam with a density of 4.8 PCF and PCM
Second: 2” gel-infused polyfoam with density of 2.5 PCF
Third: 6” pocketed carbon-steel coils
Fourth: 1” support foam

Each model also has a set of 6” foam supports along the exterior of the coils to help provide edge support. And in each mattress, the top layer includes PCM, or phase-change material, which is designed to help keep the top of the mattress from getting too warm or too cool.

Sleep Trial / Refunds

Tomorrow Sleep offers one of the most customer-friendly sleep trials available. For 365 days after your mattress arrives, you can return it for a full refund. If you decide to make a return, the company will arrange to pick up the mattress from your home.

There are only two caveats to this sleep trial. First, the company requires you to sleep on the mattress for 30 nights before you can initiate a return. Second, the 365 day trial only applies to mattresses. If you purchase any other products, such as an adjustable base or sleep tracker, a shorter trial period applies.


Standard delivery via UPS Ground is included in the price of your mattress. With standard shipping, the mattresses usually arrives within 3 business days after an order is placed. Shipping is currently only available to the continental United States.

For standard delivery, the mattress is compressed, sealed in packaging, and placed in a box that is delivered to your doorstep. You then bring the box to the room where you will use the mattress and remove it from the packaging. Within 10 minutes after unboxing, the mattress will be at about 90% of its full size and ready for you to sleep on it. After 24 hours, the mattress will be fully decompressed.

In addition to standard delivery, the company also offers white glove delivery service. This includes bringing the box into your home, unboxing, unwrapping, and setting up the mattress where you choose. This service costs $75 and up, depending on your location. For an additional $49, the company will also haul away your old mattress. Costs associated with white glove delivery are not refundable if you decide to return the mattress.

Customer Service

Most customers have had positive experiences with Tomorrow Sleep when it comes to service and support from the company. Serta Simmons has a long history in the mattress industry with an up-and-down track record as far as customer service goes. Overall, though, these companies provide a certain level of stability backing Tomorrow Sleep, and the company seems to be working hard to orient itself toward providing a quality customer experience.


Mattress Performance

Hybrid mattresses attempt to strike a balance in terms of bounce and responsiveness so that they can offer a high level of comfort and support without causing issues related to sleeping hot or sinking too deeply into the mattress. Most customers who have slept on the Tomorrow Sleep hybrid have felt that it meets these goals.


Support refers to how well a mattress promotes the proper alignment of the spine. Memory foam, which is used in the comfort layer of this mattress, can improve alignment by conforming to offer support for the body’s main pressure points. At the same time, the innerspring coils in the mattress can promote support by providing a strong base that keeps the mattress from sagging too deeply.

Our only concern with regard to support for this mattress is that the topmost comfort layer — made up of memory foam — is thin in both mattress models. While the memory foam is supported by other foams, it may not provide quite as much contouring as may be offered by comfort layers with thicker layers of memory foam.


The Tomorrow Sleep mattress is too new to the market to be able to evaluate its long-term durability. The density of the foams has a major effect on the likely durability of the mattress, and the foams that support the memory foam in this mattress are slightly less dense than we would normally prefer to see. However, we still believe that this mattress is likely to hold up well with regular use for 5-10 years.


There are two firmness choices available for the Tomorrow Sleep mattresses. On the typical firmness scale, the Medium Soft mattress is around a 4 while the Medium Firm is around a 6.

Motion Transfer

One of the selling points of memory foam is that it does not transfer much motion, which means that movement on one part of the bed is not felt on another part of the bed. While the innerspring coils may contribute to slightly more motion transfer than a mattress made entirely of memory foam, very few sleepers report issues with motion transfer on this mattress.


You can expect a minor odor when this mattress is first unboxed, but this should not last more than a few hours. There is no health risk from this “new mattress smell,” and the amount of offgassing is likely to be less than most all-foam mattresses.

Sleeping Hot

It is unlikely that people will sleep hot on this mattress for two primary reasons. First, the innerspring support core helps to limit the excessive sinking into the mattress that can inhibit airflow and cause overheating. Second, the phase-change material used in the topmost layer helps to regulate temperature in a way that counteracts sleeping hot.


While some mattresses with memory foam inhibit sex by causing a deep sinking into the mattress, the amount of bounce from the 6” of innerspring coils will prevent that from being a major issue with the Tomorrow Sleep mattress.
