Tomorrow Sleep vs. Leesa

When it comes to choosing mattresses, depending on the kind of comfort you need and your preferences, you have many options to choose from, and hybrid mattresses and all-foam mattresses are currently the two most popular construction types on the market.

Today’s comparison will be between the Tomorrow Sleep, a pocketed coil and foam hybrid, and the Leesa, an all-foam mattress. These are the popular bed in a box brands, but which one is the right for you?

Let’s take a closer look at them and find out. Last updated Feb 8, 2019 @ 5:04 pm

Tomorrow Sleep

Construction and Materials

The Tomorrow Sleep mattress is a 10″ hybrid pocketed coil and foam mattress made up of 4 layers. It comes in 2 firmness options Medium Soft and Medium Firm, and the one we tested is Medium Soft.

  • 1″ Comfort Layer – This layer is 1″ of 4.8lb Visco Elastic memory foam designed to distribute your body weight and provide pressure relief. It is coated with phase-change temperature regulating material that pulls the heat away or keeps it close to your body.
  • 2″ Support / Cooling Layer – This layer is 2″ of 2.5lb gel infused memory foam that provides additional support to your body and reduces heat retention.
  • 6″ Support Layer – This layer is made up of 6″ of pocketed innerspring coils and a 3″ thick ventilated side rail system around the coils that promotes airflow through the sides of the mattress for additional cooling.
  • 1″ Foundation Layer – This layer is 1″ of high-density base foam that serves as the foundation for the coil system.

The cover is made from phase-change temperature regulating material with a breathable open weave, and a smooth and soft finish that adds to the comfort and airflow.

Firmness and Support

Tomorrow Sleep comes in two firmness options, and the Medium Soft model that we tested scores 5-6 out of 10, with 10 being the firmest. Its top comfort layer provides a soft luxurious feel, and the underlying coils and foam provide a good support underneath which makes this mattress ideal for heavier sleepers.

The Tomorrow Sleep mattress offers a good support in all sleeping positions. It provides you with enough give in the top comfort layer to support your hips and shoulders, and with enough firmness when you switch to your back or stomach.


The Tomorrow Sleep offers a lot of comfort as well. Coils combined with the gel memory foam top layer offer a good push-back and bounce, and provide your body with nice contour and hug. This mattress is supportive and allows you to sleep soundly in all sleeping positions, while the soft cover keeps you cool and adds to the comfort.

Sleeping Hot

The Tomorrow Sleep does a good job in reducing heat due to the gel foam layer in the top comfort layer combined with the phase-change material in the covers. The nature of its innerspring coils allows a good airflow, and perforated edge panels around the coils contribute to this.

Sinkage and Motion Transfer

With the Tomorrow Sleep, sinkage is reduced to the minimum although it is only 10″ in height. The support coils regulate sinking, while the edge support layer incorporated within this mattress provides a good edge support and prevents you from rolling off of the bed. As it is a hybrid coil mattress, it has a certain degree of motion transfer, but nothing too extreme like it is the case with some competing beds.

Smell / Off-Gassing

The Tomorrow Sleep gets high marks for not having any noticeable smell upon opening the box. The hybrid coil/foam construction of this mattress minimizes the degree of off-gassing that all foam mattresses usually have.

Construction and Materials

The Leesa is a 10-inch combination of memory foam and Avena foam for additional cooling and bounce and it is composed of the following layers:

  • 2″ Top Cooling layer – The top layer is made of 2″ of cooling Avena foam, designed to provide cooling and bounce.
  • 2″ Middle layer – This layer is designed to provide support to the body and pressure relief, and it is made up of 2″ of contouring memory foam.
  • 6″ Bottom layer – This layer is made of 6″ of dense support foam and it provides the foundation for the mattress and works with the top layers to create support.

The Leesa has an extremely soft cover woven from one piece of polyester-Lycra blend fabric that works to provide a cool surface and comfort as well.

Firmness and Support

Whereas the Tomorrow Sleep comes in two firmness options Medium Soft and Medium Firm, The Leesa is a universal comfort type memory foam mattress, designed to appeal to a wide range of sleepers, and it is around a 5/6 out of 10 on the firmness scale, with 10 being the firmest.

However, firmness is largely weight dependent and I tended to compress the top layers less than Andrew who weights considerably more than I do. Therefore, Andrew did not feel that the Leesa provided much support to him when sleeping, as his heavier weight caused him to compress through the upper layers quite a bit.

The thinner construction of this mattress also caused him to bottom out when sitting up on it, which is something that the Tomorrow Sleep did not do.

While the Leesa has a soft and comfortable exterior and the Avena foam in the top cooling layer provides a bit of responsiveness and bounce, it does not provide enough support and comfort like some of the other all-foam mattresses we have tried out to date.

Andrew felt it was not supportive enough for his heavy weight, and it caused him to reach the foundation of our bed. This, if you are a heavier sleeper as well, may reduce the overall comfort and affect the quality of your sleep.

Sleeping Hot

As for sleeping hot, the Leesa does a good job here, and it is about average in this category. Its thin cover and the use of the Avena foam layer in its construction provides good air flow, makes this mattress breathable, and eliminates the feeling of stickiness usually present in memory foam mattresses.

Sinkage and Motion Transfer

As it has been already said, sinkage and motion transfer is highly dependent on sleeper’s weight and as Andrew weights around 230 lbs, he pressed through the 10″ Leesa top layers immediately upon sitting and lying on the mattress.

The sinkage of the Leesa also caused more motion transfer during the night than the Tomorrow Sleep as Andrew would sink lower than me, which caused me to roll into him.

Edge support in this mattress is minimal and Andrew’s weight compressed the bed. Lying flat seemed to disperse his weight, but at times when rolling over in the night, he would feel the harder support layer through the compressed thinner comfort layer.

Smell / Off-Gassing

There is a small degree of off-gassing/smell upon opening the box. It is due to the all-foam construction of this mattress, but it is nothing overpowering when compared to some other mattresses we have reviewed.

Which Mattress Is Right for You?

Choose Tomorrow Sleep mattress if you like:

  • Memory foam feel – Memory foam top layer of this mattress provides a good contour to your body and gives you a feeling of hug typical for classic memory foam.
  • Breathable mattress – The innerspring coil layer and aerated side support layer allow excellent airflow through the mattress while the gel foam layer in the top comfort layer and the phase-change material in the covers reduce heat retention.
  • Mattress with bounce – The support layer made of a pocketed coil system provides a good degree of bounce and prevents sinking too far through memory foam layers.
  • Sharing your bed – The Tomorrow Sleep mattress performed well on the motion transfer test, and it is a good choice if you plan on sharing your bed with a partner as your sleep will not be disturbed by shaking of the mattress when changing positions with your partner or getting in and out of bed during the night.

Choose Leesa mattress if you like:

  • Memory foam feel – The softness of the Leesa cover combined with the initial soft response from its memory foam layers provide a soft feel typical for memory foam. 
  • Sleeping cool – The thin cover of this mattress and the use of the Avena foam layer in its construction allow easier air flow, make this mattress breathable, and eliminate the feeling of stickiness usually present in memory foam mattresses.
