High-Density Foam
Air flow-enhancing Boost-X® amplifies the conforming quality and resilience of the top layers—while also creating a smooth transition from the up-top softness into the high-density base that helps your mattress keep its shape without sagging over time.
I looked at a lot of different beds before picking the M1X. It’s amazing. I tried an all-foam bed and it was just too soft for me to get comfortable. I sleep better. The bed feels cool all the time. I just love it.
