Bed-in-a-box companies are popping up every day with exciting new technology that can take your rest to the next level. But Tomorrow Sleep, a newer offering in this space, comes from Serta Simmons Bedding, which has the bench strength of designing mattresses since 1931.

Our in-depth review of Tomorrow Sleep, a hybrid design of foam and coils that was introduced in June of 2017, will show you all the years of expertise and new innovations that this brand offers, from phase change cooling technology to the highly durable pocketed steel coil system.

Though this hybrid comes in two different comfort levels: Medium Firm and Medium Soft, our review will focus on the Medium Firm option, which is the company’s best-selling model.

Read on for more details, such as pressure relief, support, cooling and motion transfer, or cut to the chase and look at the scores and overall impression.

Video Review

You will love Tomorrow Sleep if you:

  • Love memory foams – For a hybrid mattress, this mattress feels like a classic memory bed with slow-responding foams and great pressure-relieving sinkage. You will get a cradled feel with the added bonus of a durable steel coil system for support.
  • Sleep hot – Phase change technology and gel in the top layers work together with the airflow in the coil system and the aerated foam perimeter to maximize temperature regulation.
  • Want bounce – This hybrid’s coil unit gives the bed its bounce, which helps ease repositioning and keeps you from sinking too far into the mattress.

You might not like Tomorrow Sleep if you:

  • Want an all-foam mattress – Though the layers of memory materials provide great motion isolation and the feel of a memory bed, this hybrid has a durable steel coil unit which will give the hybrid some springiness and a slightly different feel than an all-foam design.

Construction (Materials & Quality)

The Tomorrow Sleep is a hybrid bed-in-a-box that works with many standard frames and bases, including platforms and adjustable bases. If you choose, the company offers a White Glove Delivery service that will deliver your new hybrid, install it, and remove your old mattress, for an additional fee.

The fully-removable cover consists of a thin, stretchy polyester nylon blend with a breathable open weave and a smooth and soft finish. With the layers, the mattress has a height of 10 inches.

layers of tomorrow sleep

  • The first layer is 1 inch of Tomorrow Cool memory foam that works to distribute your weight evenly and provide pressure relief. This layer is coated with Black Diamond Phase Change technology, a unique temperature regulation feature that pulls heat away from your body when you feel hot and keeps it close to your body if you start to cool.
  • The second layer is a 0.5-inch layer of Tomorrow Airy Comfort foam that provides additional pressure relief with an infusion of gel to reduce heat retention.
  • The third layer is 1.5 inches of Dynamic Response Foam, which provides added contouring while forming a transition between the memory materials and coils.
  • The fourth layer is 6 inches of pocketed high-carbon steel coils that support the body with a stable and durable base while adding bounce and reducing motion transfer.
  • The fifth layer is 1 inch of foam for the coils to rest on.
  • The perimeter layer is 6-inch high, 3-inch thick ventilated foam rails around the coil unit that form the hybrid’s edge support and promote airflow for temperature regulation.

The Medium Soft version will not have the third layer of Dynamic Response Foam and will include an extra 1.5 inches of the Airy Comfort foam. Also, the hybrid’s coils use slightly thinner wire, which allows the mattress some extra give.

Firmness (Support & Feel)

We scored the Medium Firm Tomorrow Sleep hybrid at a 6.5 out of 10 on our firmness scale (if you're not familiar with our scale you can see how it works here), where 10 is the firmest, which places it just slightly on the firmer side of Medium. We think this option will accommodate a wide variety of people, but the company also offers a Medium Soft option that they score at a 4 out of 10, for those needing extra pressure relief.

The bed feels soft and cool to the touch due it top layer’s phase change technology, and when you lie down, you feel the memory materials begin to activate as you slowly sink into the mattress. With the Medium Firm option, you should experience a slightly deeper cradling, but not quite the deep hug that can make you feel trapped.

The top foam layers are slower-responding, so they do take a few seconds to regain their shape when pressure is released, but they are slightly quicker to react than some memory products.

As a hybrid, this bed truly is a blend of two very different mattress feels. The deep bounce from the steel coils is mitigated by the minimal bounce of the surface layers. Overall, it has a medium-level bounce when the effects of both materials are taken into account.

Combination sleepers will likely prefer this model over the Medium Soft since its versatility accommodates most positions, and the additional support and bounce will help with repositioning.

Most back sleepers will feel well supported by the strong steel coil layer as the memory foam supports their lumbar region.

Most side sleepers will enjoy the amount of evenly-distributed pressure relief of the top foam layers and firm support for their spine. Those wanting the extra pressure relief of a slightly deeper hug experience, especially those who are significantly lighter, may prefer the Medium Soft option.

Stomach sleepers should be well served by the Medium Firm option of this hybrid that will support their weight at their heaviest points and not allow their hips to sink too deep, an experience that can force the spine into uncomfortable positions.

According to the company, 70 percent of their buyers purchase and are satisfied with the Medium Firm option. While we think this version will accommodate most body types and position preferences, slightly heavier individuals may prefer a firmer bed.

Motion Transfer

This mattress performs really well with motion transfer, especially compared to other bed-in-a-box hybrids. This can be attributed the three inches of memory materials, which isolate motion and keep it from traveling to the other side. Also, the coils of the innerspring unit are pocketed, which means they flex individually and do not affect their neighboring coils.

If you sleep with a partner and are worried about disturbing each other’s sleep, this hybrid is a great choice.

Edge Support

Bed-in-a-box brands with quality memory foam close to the surface do not tend to excel with edge support because of the nature of memory materials. Tomorrow Sleep has mitigated some of this effect by inserting foam rails around their coil unit. Some noticeable compression will occur when you sit, but you should be able to sleep on the side of the bed without a significant change in support.

If you sleep alone or share a larger size mattress, edge support may not be a concern of yours, but those who share smaller beds and sleep closer to the edge may want to consider it.

Other Considerations

  • Two Firmness Options – When ordering this bed, you can specify your firmness preference, choosing either the company’s Medium Soft or Medium Firm.
  • Trial Period – The company gives you a full 365 nights, or a whole year, to decide if this mattress is right for you.
  • Warranty – This bed comes with a 10-year warranty.
  • Shipping – This mattress ships to the continental U.S. for free.
  • Optional White Glove Delivery – Tomorrow ships to your house in a box for easy at-home set up but you may also choose to have your mattress installed at an extra cost.
  • CertiPUR-US® Certified – This certification indicates that the mattress was evaluated by a third-party organization that tests foams for non-existent or safe levels of harmful emissions, chemicals, or heavy metals, such as formaldehyde, lead, or ozone depleters.
