Tomorrow Sleep Memory Foam Mattress Review

In this new review of the Tomorrow Sleep memory foam mattress, we take a look at the second mattress offering from Tomorrow Sleep, which is backed by the mattress industry heavyweights Serta Simmons.  Tomorrow Sleep originally came onto the market with a hybrid mattress, which we reviewed here, and which we ranked high and as one of the top hybrid mattresses on the market.

Tomorrow Sleep has now introduced an all foam mattress to meet the demand for memory foam mattresses, which are a popular mattress choice for many who aren’t interested in the feel of coils of which hybrid mattresses are known for.

In this Tomorrow Sleep foam mattress review, we give our opinions on this new mattress after taking it for a test sleep period, and outline the pros / cons of this new mattress. Hopefully this review helps you out in making a decision on your next mattress purchase!

Construction and Materials

The Tomorrow Sleep foam mattress is a 10″ all foam mattress made up of 3 layers of various foams.

  • 1″ Top Comfort Layer – This layer is 1″ of cooling open cell memory foam that is infused with graphite and coated with a temperature regulating coating which provides cooling and comfort to the mattress.
  • 2″ Support Layer – This layer is 2″ pressure relieving gel swirl memory foam, which provides primary support and cooling to the mattress, as well as pressure relief and contour.
  • 7″ Foundation Layer – This layer is 7″ of  high density base foam that acts as the foundation and provides deep compression support for the body during sleep.

The cover of the Tomorrow Sleep memory foam mattress mattress incorporates an innovative phase change temperature regulating fabric that helps transfer heat away from the body when hot, and retain heat when cool – which really does deliver a cool sleeping surface.

We have felt this material in a few mattresses we have reviewed, including the Tomorrow Sleep hybrid mattress, The mattress feels cool to the touch and sleeps cool as well which we will discuss more in our review below.

This in-depth review of the Tomorrow Sleep memory foam mattress evaluates all of the criteria we use to determine what constitutes a good mattress, which includes firmness / support, comfort, sleeping hot, and other features as outlined below. Review updated May 2018

Firmness & Support

In terms of firmness, the Tomorrow Sleep comes in a universal comfort firmness option, which is on average what the majority of sleepers prefer.

We rate the Tomorrow Sleep foam mattress as a 6 out of 10 (10 being firmest), on the firmness scale. The all foam construction provides firmer support on the lower support layers, with softer layers up top.  The mattress feels different depending on your weight, as for me (Andrew), I weight 230 lbs so I often compress through the top comfort layers and come to rest on the lower support layers.

This tends to make mattresses with firmer support core layers feel firmer to me, while Kaye, who is half my weight, feels more of the softer comfort layers. So between the two of us, we often have different opinions on the feel of the mattress.

As it pertains to support, the all foam construction of the Tomorrow Sleep provides more hug and contour for side sleeping, which something you want if you are this type of sleeper.

Side sleepers prefer mattresses that have more “give” in them, so that your shoulders and hips get more contour and allow them to sink down into the mattress, and at the same time remain in alignment so that your body doesn’t sink or sag.

One caveat: this mattress, at 10” high, is on the thinner spectrum compared to many of the beds that have come out on the market lately, and tends to be less ideal for heavier sleepers such such as myself (Andrew), who often will compress these thinner mattresses with my heavier weight.

That is the one drawback we have found sleeping on 10” beds given my heavier weight, as well as our combined weight as a couple.

The Tomorrow Sleep hybrid mattress is one of our top picks for Side Sleepers, due to the construction and design of that mattress which provides the comfort and support needed for side sleeping.

Back sleepers and stomach sleepers usually prefer a firmer mattress, but the Tomorrow Sleep foam bed is still good for most sleeping positions.   You may want to choose the Tomorrow Sleep hybrid bed if you are a back or stomach sleeper, however, as it may be a better choice for these sleeping styles.

All in all, the Tomorrow Sleep foam mattress provides a good overall supportive sleep environment for all sleeping styles, but as mentioned, probably more so for side sleepers in the all foam model, and back and stomach sleepers for the hybrid model.


Going hand in hand with support, comfort is something that is vital when choosing a mattress. After all, you spend a 1/3 of your life in bed, so it needs to be comfortable, right?

As mentioned, Kaye and I prefer the feel of memory foam compared to other types of mattresses, as we like the feel of hug and contour that memory foam gives you when sleeping. Hybrid coil models generally tend to be on the firmer side, and impart that “sleeping on top of” feeling, vs  a “sleeping down in” feel that memory foam gives.

This is very subjective and something that we preach is individual taste.  You like what you like, and should choose a mattress that matches that style.  In this case, the Tomorrow Sleep foam mattress gives that classic memory foam feel that we personally like quite a bit.

If you are looking for a “floating on top of “ or firmer feel, you may want to possibly choose the hybrid model (which actually is quite confirmative and contouring compared to most hybrids).

The layers of foam and the soft exterior cover all do a great job at providing a very comfortable sleeping environment and lend themselves to making this a rather comfortable bed.

Sleeping Hot

One important criteria for evaluating any mattress like we do here at Memory Foam Talk, is whether or not it sleeps hot.

We live in Texas, and it is pretty much 80 degrees even in the winter some time, and when sharing a bed, one thing we do NOT like is to sleep hot. It kills any cuddling or sleeping next to each other, if we are sweating due to a hot mattress.

Memory foam or all foam mattresses tend to have a problem with sleeping hot if they don’t employ any specific cooling technology.

Hybrid coil beds or latex beds by the nature of their materials sleep much cooler, but the characteristics of foam often cause memory foam mattresses to sleep much hotter and at times cause sweating.

The Tomorrow Sleep mattress does a good job at addressing sleeping hot by the use of gel memory foam and the phase change temperature regulating material in the cover. The exterior of the mattress did feel cool to the touch, but at times we were a little warm.

While we didn’t wake up in sweat, there was a degree of warmth when sleeping on the Tomorrow Sleep memory foam mattress compared to their hybrid. Once again, this is more due to the overall design of the mattress, being all foam, vs. anything specific to the bed.

Sinkage & Motion Transfer

As we ALWAYS preach, sinkage and motion transfer is very weight dependent. As I (Andrew) weigh 230 lbs, this has a direct correlation to how much sinkage we experience when testing mattresses. Kaye, who is half my weight, doesn’t have this problem.

But as a couple, we have to take this into consideration as my heavier weight will often cause her to “roll into” me due to our weight differential.

With the Tomorrow Sleep foam mattress, the 10” thickness results in my heavier weight causing me to sink down quite a bit on the mattress when sitting up and sitting near the edge.

Tomorrow Sleep mattress profile

When lying down, my weight is dispersed across my body rather well, but sitting causes me to compress the mattress quite a bit.

As for motion transfer, one of the great things about all foam mattresses is that they are excellent for minimizing motion transfer compared to latex or hybrid coil mattresses.

The inherent properties of foam provide for much less motion transfer compared to latex or innerspring coils, which by nature are much bouncier and responsive.

We did not experience much motion transfer with the Tomorrow Sleep foam mattress when moving around and changing positions during the night, or getting in our out of bed, which is a great thing.

As mentioned, many other mattresses will cause motion which can cause sleep disruption for your partner during the night, and if you’re like us – result in 3am disagreements or arguments when I bounce Kaye up like a trampoline when getting back in bed after a late night bathroom break!

Thankfully this isn’t the case with the Tomorrow Sleep mattress.

Smell / Off-Gassing

One thing about memory foam mattresses, especially ones that are sent in the mail via the “bed in the box” model, is that smell that often results when the mattress is opened from the packaging after shipping.

This is due to the chemicals that are in the foam, which when compressed and put in plastic will cause a degree of odor called “off-gassing”.

Some beds do better at others with this, with some we have tested being unbearable even after several days, while others having no odor at all. TheTomorrow Sleep foam mattress is about average in this regard.

As an all-foam mattress, it needed an overnight period to allow the smell to dissipate before placing in our room. This is to be expected from all-foam mattresses, as explained above, which is normal and about average.  Nothing specifically over the top odorous, but also at the same time not completely odor free.

Customer Service

Tomorrow Sleep provides a good degree of customer service, given that they are backed by an industry heavyweight, Serta Simmons, they come to the market with much less risk than many start-up mattress companies.

One thing you don’t have to worry about is them going out of business!  The also have adopted the 365 night sleep trial pioneered by Nectar – which provides you with much lower purchase risk by allowing you to get your money back no question asked within a year! 

Something that not many companies do, and something that shows their confidence in their product.

Key features:


The Tomorrow Sleep is a very reasonable mattress, coming in at $720 for a queen. This is about the norm for mattresses in this range, and given the materials and design about right.

Twin XL$570$460
Cal King$1175$920


The Tomorrow Sleep memory foam mattress is the latest offering from Tomorrow Sleep, and their all foam mattress that compliments their original hybrid mattress and their complete sleep line.

The Tomorrow Sleep foam bed provides an all foam mattress feel for those that like the traditional memory foam mattress feel, at a great price with good materials.

This mattress provides the traditional memory foam feel of body hug and contour with good support for all sleeping positions without sleeping hot which is important for couples sharing a bed. The bed provides enough give for side sleeping, while also providing enough firmness if you sleep on your back or stomach.

We feel the combination of the various foam layers with the soft exterior cover provides a comfortable, supportive sleeping environment and is a good choice if you are a fan of memory foam.
