Tomorrow Sleep, a subsidiary of Serta Simmons Bedding, designs and sells an integrated sleep system, which includes a hybrid mattress, bedding, and a sleep monitor. Made in the USA, Tomorrow mattresses feature a combination of memory foam comfort layers and a pocketed steel coil layer for support, and are available in two firmness levels.

Size and Firmness

Tomorrow Sleep hybrid mattresses are available in six sizes:

Twin or Single

Twin XL



Full or Double



California King

Tomorrow mattresses feature a multi-layer construction that combines memory foam top layers for comfort and a wrapped coil base layer for support. The specific composition of these layers varies depending on the chosen support level: Medium Soft or Medium Firm. According to Tomorrow Sleep, 70% of their customers prefer the Medium Firm support level, but they encourage sleepers to take advantage of the 100-night home trial and try the mattress for themselves.


Tomorrow Sleep hybrid mattresses are designed to incorporate the best features of memory foam mattresses and traditional innerspring mattresses. They feature a combination of foam comfort layers and a coil support layer. The wrapped coils move independently of each other, so the transfer of movement is limited. The memory foam regulates body temperature to keep you cool as you sleep. Additionally, Tomorrow Sleep mattresses have a rail system around the edge of the mattress to help it keep its shape, which prevents you from slipping from the bed when sitting on the edge.

Plan Details

Any product can be returned for up to 100 days after purchase. Tomorrow Sleep suggests customers try breaking in their mattress for 30 days before requesting a return. Once the 30-day period has passed, you may either exchange the mattress for a different model or return it for a full refund. Tomorrow Sleep will arrange to pick-up the expanded mattress, since you will be unable to compress it back into a shippable size. Tomorrow also offers a 10-year limited warranty, which covers manufacturing defects. However, this warranty does not cover mattress sag that is 1.5” or less.

Tomorrow Sleep hybrid mattresses are shipped for free within 2–3 business days to the contiguous United States.

Financing is available through Affirm for up to 18 months, starting at 0% APR.

Customer Support and Reputation

Since it was launched in June 2017, Tomorrow Sleep has not yet earned a Better Business Bureau or TrustPilot rating, but online reviews are generally favorable. Some reviewers express satisfaction with the coolness of the memory foam surface, but can find it difficult to reattach the removeable mattress cover. Over 400 reviews on the Tomorrow Sleep website account for a 4.9 out of 5 rating from its customers.
