So this is absolutely the most comfortable thing I’ve laid on... BUT! I chose this because it said it has “cooling” in the filter I used to find the perfect match and it is hot as heck. I’m so torn because it finally had given me relief from back pain but I’m sweatinggggg in the middle of the night with ceiling fan blasting and a fan directly pointed at me from the foot of the bed! So if you’re a hot sleeper.. this is not for you.
