I was skeptical about the cooling claims, but after a few hot nights the carbon layer actually keeps the surface noticeably less warm than my old mattress. The plush top gives just enough sink without losing support, and I’ve stopped waking up with a sore back.

I was worried about sleeping hot, but the carbon-infused cooling layers actually keep the surface cool through the night. The plush top is soft yet supportive enough for my side-sleeping position.

The middle coil design keeps me from sinking in the center, and the surface stays noticeably cool even after a full night. I wake up without the usual stiffness in my shoulders, which hasn't happened with a mattress in years.
