What's the skinny on Tomorrow Sleep mattresses? They are hybrid memory foam with coil. Are they worth the extra cost (compared to memory foam)? Thanks.

Hi subcommitteez,

Welcome to the forum! :)

What's the skinny on Tomorrow Sleep mattresses? They are hybrid memory foam with coil. Are they worth the extra cost (compared to memory foam)?


They have been brought up here on the forum before. See post #104 here .

From that post:

They have two different comfort offerings (from information provided to site member Ari by Tomorrow Sleep).
Medium firm
1" 3.5lb Memory Foam Layer
1/2” 2.5lb Air Cooled Comfort foam layer with Gel (not sure if this is memory foam or poly foam)
1.5” Dynamic Response Foam Layer (density was not provided – this is probably polyfoam)
6" coils at the bottom for additional support."

Medium soft
1” 4.8 lb Viscoelastic (memory foam)
2” 2.5 lb foam layer with Gel (not sure if this is polyfoam or memory foam)
6” Series coil
6” x 3” Foam rails with Side Ventilation
1” thin base foam layer which the coils rest upon

Tomorrow Sleep is a managed independent of Serta Simmons Bedding (SSB) by Bryan Murphy, a successful eCommerce/Software entrepreneur (WHI Solutions). SSB is building their hybrid mattresses for them (see this article ).

The Medium Firm uses a total of 3” of comfort materials, with the memory foam being a bit lower than what I would normally recommend (3.5 lb vs. 4 lb), and they didn’t provide the density of the “Dynamic Response Foam Layer”. The Medium Soft uses a higher density memory foam, and the polyfoam layer beneath that uses a better density of foam. There isn’t more detailed information on the spring unit listed on their web site.

They unfortunately don’t provide detailed information about each mattress configuration on their web site, and I would advise caution against purchasing anything before knowing of all of the componentry on the inside of the product.

Hi Phoenix, are the 2.5-2.6 PCF memory foam layers in the Medium Firm and Medium Soft too low to consider this mattress durable enough for the long run with folks that have a lower BMI (e.g. 18-22)?

Also, should I be measuring the 2.5-2.6 PCF memory foam layers against the 4lb memory foam standard or the 1.8-2lb polyfoam standard?

Thanks!

Hi freddie89,

Thanks for the questions. I will assume that the specific specs are correct and were passed on to you from the company, as the website only has the general descriptions. Of course with lower BMI one will have less breakdown and less sagging.

With comfort layers of 2" at 2.5 or 2.6 lb density, one should at least proceed with caution, as this is a lower density than most higher quality memory foams. I understand each type has a one-inch piece of higher quality / higher density memory foam.

Regarding your second question, I am not entirely sure what you are asking, but you should be comparing all memory foam to the memory foam standards and not the 1.8 - 2.0 lb polyfoam standard. Hope this helps.

Thank you,
Sensei
