Tomorrow Sleep aims to combine the best of innerspring and memory foam mattresses with this quality-for-money hybrid design. Combining the responsiveness and bounce of a pocketed coil system with the contouring support of memory foam, this is an excellent all-round mattress that provides total comfort, support, and cooling throughout the night.

Tomorrow Sleep is one of the latest companies to join the mattress market, backed by Serta Simmons Bedding, one of the largest manufacturers of mattresses in the United States with over 100 years of experience.

The Tomorrow Sleep Hybrid mattress is a culmination of that experience, offering a cooling mattress with premium support, comfort, and contouring and two different levels of firmness to provide an option that suits a wide range of sleepers.

Tomorrow Sleep uses a combination of memory foam layers and their Tomorrow Individual Support Pocket Coil system. The memory foam layers provide excellent pressure relief and comfort but are also infused with gel and have a temperature regulating design to provide all the benefits of memory foam without the overheating side effects.

The company maintains a commitment to eco-friendly materials and all their foam components are CertiPUR-US certified with no toxic materials used in the manufacturing process. What’s more, the hybrid model is hypoallergenic and 100 percent latex free, making it ideal for anyone concerned about allergies, dust mites, or bed bugs.

Overall, the quality of this hybrid design speaks for itself, offering a durable mattress that reviews suggest will keep you comfortable, supported, and well-rested for years to come. To back this up, Tomorrow Sleep offers a 10-year warranty on the mattress, as well as a full 365-night sleep trial period, so you can test your mattress completely before deciding if it’s right for you.

4 Reasons to Pick the Tomorrow Sleep Hybrid Mattress

You want a choice in firmness levels: Tomorrow Sleep offers the choice between a Medium-Soft and a Medium-Firm model, allowing you to choose the mattress that suits your sleep style.

You like the feel of an innerspring mattress: The Tomorrow Sleep mattress takes the best of spring and memory foam mattresses, providing the contouring support of memory foam but with the added bounce and weight distribution of an innerspring mattress.

You like the contouring support of memory foam: Memory foam mattresses provide unparalleled support to pressure points, and the Tomorrow Sleep’s multiple layers of memory foam will do just this.

You like memory foam but sleep hot: Memory foam’s biggest downfall is that it doesn’t regulate body temperature as well as other types of mattresses. The Tomorrow Sleep’s gel-infused foam layers, combined with a well-ventilated coil system tackle this obstacle excellently.

Firmness & Support

While many mattresses have just one level of firmness, Tomorrow Sleep have gone one step further in ensuring their mattress is suitable for all their customers. The Tomorrow Sleep Hybrid mattress comes in two firmness options: Medium Firm and Medium Soft.

The Medium-Firm option is designed to suit the majority of sleepers, providing a more solid surface that is ideal for stomach and back sleepers in particular, while still being a popular all-rounder. The Medium-Firm model is about a 6 on the firmness scale, with 10 being the firmest.

The Medium-Soft model, in contrast, provides a much softer surface, with more hug and contouring support than the Medium-Firm. This model is about a 4 on the firmness scale and is ideally suited to back and side sleepers who prefer a softer, plush feel to a mattress.

While the Medium-Firm model provides a firmer surface than the Medium-Soft model, both mattresses aim to provide a good balance between comfort and support for all sleeping preferences.

Tomorrow Sleep reports that up to 70 percent of their customers prefer the Medium-Firm model to the Medium Soft, but this is entirely dependent on your personal preferences and body type. If you are a heavier sleeper, you may find the Medium-Firm more appropriate to provide full-body support when you sleep, whereas the Medium-Soft model may provide a more comfortable sleep surface to lighter people.


The two models of the Tomorrow Sleep Hybrid mattress are constructed slightly differently in order to achieve their individual level of firmness.

The Medium-Firm option is constructed with five layers of memory foam and individually wrapped coils, while the Medium-Soft option is constructed from four layers, with both models measuring 10-inches in height.

The Medium-Firm Tomorrow Sleep Hybrid mattress is described as their ‘most popular feel, ideal for most sleepers’, and is composed of six layers, designed to provide a more solid sleep surface for people who like extra support when sleeping.

The bottom three layers of the mattress provide the support system, with the top three layers designed to add comfort – all coming together to create the Tomorrow Sleep’s contouring, comfortable feel.

The bottom layer of the support system is composed of a 1-inch layer of high-density base foam designed to provide both durability and full-body support to the mattress, as well as added ventilation.

On top of this layer is a 6-inch Pocketed 800 Series 0.083-inch Gauge High-Carbon Steel Coil system, which is encased by a 3-inch thick and 6-inch high ventilated foam side rail to provide edge support and allow air to easily pass through the mattress.

The third layer of the mattress is a 1.5-inch comfort layer of dynamic response memory foam, designed to provide a balance of both comfort and support. On top of this is a 0.5-inch layer of Airy Comfort Memory Foam with Gel, with 2.5-lb in density.

This layer is specifically designed to contour to the body for unparalleled support, with the gel helping to absorb heat from the body and help regulate body temperature throughout the night.

Finally, the top layer is a 1-inch thick 3.5-lb density Black Diamond memory foam layer, also infused with cooling Phase Changing Material to provide a supportive, firm surface that also helps to absorb body heat and wick it away from the body.

The overall construction of the Medium-Firm Tomorrow Sleep mattress provides a supportive sleep surface that should suit most sleepers but is particularly suited to stomach and back sleepers, as well as athletes who need extra support for muscle growth and repair.

Medium-Soft Tomorrow Sleep Mattress:

The Medium-Soft Tomorrow Sleep model is identical in design when it comes to the base support layers. It has a 1-inch thick base foam layer for durability and full-body support, topped by the same 6×3-inch foam side rail that wraps around a 6-inch pocketed coil system for spring and body support.

The comfort layer of the Medium-Soft model differs from the Medium-Firm mattress in that it consists of just two memory foam layers. On top of the coil system is a 2-inch 2.5-lb density airy comfort memory foam layer infused with gel to wick excess body heat away from the mattress and provide a supportive, contouring surface.

Topping this layer is a 1-inch thick 4.8-lb density viscoelastic memory foam layer with Phase Change Material to provide added temperature regulation and a supportive yet comfortable surface, ideally suited to side and back sleepers who enjoy a plusher feel that cradles the body.

Temperature Regulation & Motion Isolation

The combination of memory foam and individually wrapped coils means that this hybrid mattress performs extremely well in motion isolation tests.

The coils are designed to flex independently to evenly distribute you and your partner’s weight across the mattress, providing individual support that allows you to move without disturbing each other’s sleep.

Likewise, memory foam is excellent at isolating and minimising movement. These two components combine to provide a highly supportive sleep surface, regardless of how much the person next to you moves around.

If you are concerned about sleeping hot on this mattress, you’ll be pleased to know that the Tomorrow Sleep also performs very well in regulating body temperature while you sleep.

The Hybrid mattress is designed to provide a cooling sleep surface in three ways:

  • The top two memory foam layers are infused with phase change material and cooling gel to pull heat from your body
  • There is a ventilated outer-edge foam rail to help heat leave the mattress
  • Individually wrapped coils allow air to flow through the mattress and out via the base


When it comes to bounce back, the innerspring coils and memory foam layers in the Tomorrow Sleep mattress work in perfect harmony. While many innerspring mattresses can form an impression of your body over time, the Tomorrow Sleep mattress includes memory foam layers that are designed to contour your body while you sleep and recover quickly when you get up.

That being said, the individually wrapped coils in the Tomorrow Sleep give it a faster response time than a traditional memory foam mattress, allowing you to move around comfortably at night without experiencing the classic sinking feeling an all foam mattress might create.

The Tomorrow Sleep performs well on responsiveness even on the edges of the mattress, with a unique rail system that is designed to maintain the mattress structure all the way to the edge of the bed. This system means that even when you near the edge of your mattress, you’ll stay supported and comfortable without feeling like you’re about to roll off.

Eco-Friendliness & Smell

All of the foams used in the Tomorrow Sleep are CertiPUR certified to ensure they are safe and non-toxic. CertiPUR-US approved foam guarantees the foam is made without ozone depleters, PBDEs, mercury, lead, formaldehyde, or phthalates, and are low in VOC emissions, for improved indoor air quality.

As with many foam mattresses, the Tomorrow Sleep is reported to have a ‘new foam smell’ when first unpacked. This smell does, however, dissipate within the first couple of days of being unpacked and shouldn’t smell after a few days of airing out.


For its quality, the Tomorrow Sleep is very fairly priced. While it’s not a budget mattress, the Hybrid model offers excellent value for money at $990 for a Queen-size bed.

Designed to be replaced every 8-10 years, and with a 10-year warranty, you’ll be investing in a bed that’s made to withstand the test of time and provide a comfortable, cooling, and contouring sleep surface.

Sleep Trial Period & Warranty

Tomorrow Sleep excels when it comes to their sleep trial period, with a full 365 nights to try the mattress for yourself and make sure it’s right for your needs.

If you don’t like the mattress by the end of the 365-night sleep trial period, you can simply return it for a full return, no matter what shape the mattress is in.

Additionally, the Tomorrow Sleep mattress comes with a 10-year warranty in which you can return your mattress should you encounter any problems with it.

Frequently Asked Questions

Should this mattress be flipped, and if so, how often?
This mattress is not designed to be flipped, as the layers in both the Medium-Firm and the Medium-Soft Hybrid models are specifically positioned in an order that offers premium support and comfort while you sleep. Just make sure you have your mattress laying with the grey side down, so you know you have the mattress the right side up.

What frame should I use with a hybrid mattress?
Your mattress will provide the most support when placed on a type of platform, but this can be in the form of an adjustable bed base, a platform bed, wooden slats, or a traditional box spring. The bonus of this is that even if you change bed frames in the future, the Tomorrow Sleep Hybrid will still be suitable for any style you choose.

How long does it take to set up the Tomorrow Sleep Hybrid mattress?
The Tomorrow Sleep is conveniently delivered in a box, making it easy to transport to your bedroom and set up. Once you get the mattress out of its box, it should expand to over 90 percent of its height within 10 minutes.

Within 24 hours, the mattress should be completely expanded, although it is safe to sleep on before this time period if you choose.

Final Verdict

Tomorrow Sleep’s mission is to create the perfect environment for any sleeper and their hybrid mattress has all the features to do just that. Offering a fantastic balance of comfort, bounce, and contouring support with premium temperature regulation, this is a bed-in-a-box that really pushes industry standards.

Made in the United States with certified non-toxic materials and with a 10-year warranty, the Tomorrow Sleep is a premium, great value mattress with lots of positive customer feedback that speaks for itself.
