Tomorrow Sleep Foam Mattress Review

Tomorrow Sleep is the “direct-to-consumer” arm of Serta Simmons Bedding (which also makes the Simmons Beautyrest and Serta iComfort lineups).

Nerd Score: 4.6/5

Our Verdict: Looking for an affordable memory foam bed that’ll satisfy a temporary solution? If so, the Tomorrow Sleep Foam mattress may be for you. With three layers of breathable foam designed to keep you cool and supported, the Tomorrow Sleep mattress will contour around your body, helping to relieve pressure and distribute weight evenly. Because the Tomorrow Sleep Foam is not as pricey as other all-foam beds, this bed may not work for you if you’re hunting for a more durable mattress with greater longevity.

The Tomorrow Sleep Memory Foam mattress is the entry-level mattress in Tomorrow Sleep’s lineup. It is the affordable option, the training wheel option for anyone wanting to try a memory foam mattress without breaking the bank or making too much of a long-term commitment.

It’s a good fit for a temporary or short-term sleeping situation. A college dorm. A guest room.

Tomorrow Sleep is the “direct-to-consumer” arm of Serta Simmons Bedding, which also makes the Simmons Beautyrest and Serta iComfort lineups.

That connection sets it apart from the crowd. Serta Simmons Bedding is the largest mattress manufacturer in North America. The company has been making mattresses since the 1870s.

That kind of experience should mean something to anyone who is overwhelmed by the she sheer number of mattress options a person can find both online and in retail stores.

The Tomorrow Sleep Memory Foam comes in at an affordable price point. The quality is good, not great. But it wasn’t built with expensive materials for a reason.  Tomorrow Sleep set out to make a more affordable, memory foam version of its hybrid mattress and did exactly that.


Here are some cool things to know about the Tomorrow Sleep Foam Mattress:

  • Breathable open-cell construction infused with graphite
  • Eco-friendly foams certified by CertiPUR-US; environment and sleeper friendly
  • Cooling gel swirl memory foam contours to body, distributes weight, relieves pressure
  • 365-night trial period, among the best in the industry
  • Designed to work with any frame or surface, even the floor
  • Parent company has nearly 150 years of experience making mattresses
  • Made in the USA



The Tomorrow Sleep Memory Foam mattress is a full-foam mattress.


The top layer is made with “open cells” and infused with graphite. The second layer has cooling gel imbedded into it. Both elements should work together to keep you if not cool, then at least comfortable while sleeping on a foam mattress. Airflow and gels are the best way to attack that traditional memory foam problem. This mattress has both.


The Tomorrow Sleep Memory Foam mattress is quite firm. For that reason, I’d recommend this more for people who sleep on their back or stomach. If you’re a side sleeper, the mattress just won’t contour enough around your shoulders or hips to be comfortable. (That is, unless you’re sure you prefer an extra-firm mattress. If so, you know what you like.)

Motion Transfer

The base layer on the Tomorrow Sleep Memory Foam mattress has a more dense construction than most foam mattresses. It’s going to withstand some movement, enough so you and your partner can sleep undisturbed.

Edge Support

The edge support on the Tomorrow Sleep Memory Foam mattress will likely be find, but not exceptional, for the first years that you have it. As the top layers degrade, so will your edge support. You’re going to want to pull back on sleeping on the edges.


The Tomorrow Sleep Memory Foam mattress is an all-foam mattress that’s pretty straightforward in its construction. The first two layers are a bit less dense than you’d find on average in a memory foam mattress, but the base layer is also stronger than you’d find on average so it balances out. Based on that, you have to know that this mattress was built for a shorter life and more like a temporary situation (dorm, guest room, etc.)

The top layer is a 1-inch memory foam with about a 2.8-pound density. They call this an “open-cell” memory foam. Any construction advances that mention open channels, open cells tell the story of what the company has done to keep the mattress cool. Memory foam mattresses are known to overheat and modern companies are hyperaware of needing to take measures to alleviate the overheating.

The second layer is a 2-inch memory foam with a “gel swirl” with about a 2.5-pound density. By the same token, if a foam layer is described as having gel in it, the same concept applies. The gel cools the foam to keep you from basting in your own sweat like a nice piece of brisket.

The third layer is a 7-inch high resiliency foam with a 2-pound density foam for support. This base layer is a heavier density than what you’d find elsewhere. That part won’t lose support over time. It’s the top two layers that will show the wear and tear after perhaps 4 to 5  years.


Here is a breakdown of the Lull specifications:


  • Twin: 38″ x 74.5″
  • Twin XL: 38” x 79.5”
  • Full: 53” x 74.5”
  • Queen: 60” x 79.5”
  • King: 76” x 79.5”
  • Cal King: 72” x 83.5”

The Tomorrow Sleep Memory Foam mattress comes with a 365-day trial period. You have plenty of time to KNOW if this mattress works for you. You can return it for free at anytime after the first 30 days and before a year ends for a full refund.

That trial period is the best offered among direct-to-consumer mattress companies.

Most will give you about 100 days.

Most also ask you to keep the mattress for at least 30 days—you break in the mattress like a pair of shoes. After that, if you return it, you get a full refund of the purchase price, and they’ll come and pick up the mattress.


The Serta Simmons warranty for the Tomorrow Memory Foam mattress is in line with industry standards, but please note that it only covers things like the mattress sagging or the foam not expanding out of the box.

It does not cover comfort. It’s not realistic to expect the mattress to be just as comfortable 10 years from now as the day you got it. Based on the materials, you can expect to get a good 4-5 years of comfort life out of this mattress with every night use.

Delivery & Setup

The Tomorrow Sleep Memory Foam mattress ships free to you and comes compressed and rolled in a box. It can be delivered in 2-3 business days. If you set it up yourself, simply take it out of the box and plastic, place it on its base and watch it come to life in roughly 10 minutes and fully expand within 24 hours.

You can set up the mattress or chose White Glove service and have them set it up for you. Prices start at $75 and vary by location. For an additional $49, Tomorrow Sleep will remove and dispose of your old mattress.

Customer service

The customer care people at Tomorrow Sleep are most easily reached by phone or chat, but only during business hours.


low $$ to low $$$ (See scale below)

$$$$$2,000 – $4,000

This is among the most affordable mattresses you will find online in the direct-to-consumer mattress universe. For example, the Tomorrow Sleep Hybrid is roughly $200-$250 more that this all-foam version.

The Tomorrow Sleep Memory Foam mattress is a decent mattress for the price. The materials aren’t as sexy as those in its hybrid brother in the Tomorrow Sleep line. And there are better options with higher quality materials if you’re willing to spend more.

However, if you want something new, from a reputable company, that is relatively inexpensive, this is a solid choice. At the end of the day it was manufactured and shipped to you from the leading mattress producer on this continent, a company that has nearly 150 years of experience doing this mattress thing. That’s Serta Simmons Bedding.

This might be a good mattress to stick in a guest room, use at college or a summer home. Maybe you just plan to buy another one when you’re better situated financially. The Tomorrow Sleep Memory Foam mattress is a decent choice to fill in the intervening years.
