Hello
What is your opinion about a mattress I tried and that I liked,
.
The composition is this:
1 - Suport Core: 17 cm High Resilience Foam FR 30 Kg/m3
2 - Second layer: 3 cm Memory Foam FR 40 Kg/m3
3 - Third layer: 2 cm Cooling Gel Foam FR 30 Kg/m3
The densities are the ones I wrote above, not the ones that appear in the link I sent. That is the UK site, but in the site of my country the densities appear slightly lower.
Thank you
Hi mega_biscoito.
I am glad you asked. I’ll translate your info for our US-based followers
Comfort layers
2 cm Cooling Gel Foam FR 30 Kg/m3 …1.8 lb/ft3
3 cm Memory foam 40 Kg/m3 …… 2.5 lb/ft3
Support
17 cm High Resilience Foam FR 30 Kg/m3 … 1.8 lb/ft3
While the support core polyfoam layer meets the durability guidelines … I would place a serious caution for the two comfort layers you listed (even for lower BMI individuals in terms the durability and useful life of this mattress. You can review each mattress component against the foam quality and density specifications in Step 3: “Identify the Weak links” in the mattress durability guidelines here
To sum up as it relates to the specs you listed:
If you are in a low and normal BMI range I’d make sure that any memory foam (or gel memory foam) in a one-sided mattress has a density of at least 4 lb/ft3 (64 Kg/m3)
If your BMI is 30 or higher then I would make sure to look for higher densities for both support and comfort layers. I’d make sure that the polyfoam has a density of at least 2.0 lb/ft3 (32 Kg/m3) and the memory foam (or gel memory foam) in a one-sided mattress of 5.0 lb/ft3 (80 Kg/m3)
