Idk what words to use to express how big of a difference this cooling mattress pad has made on my bed. It’s super comfortable, I fell right to sleep not much tossing and turning like usual. It’s like a brand new mattress. Aside from the comfort it looks good. My bed sits up higher and makes the comforter set look plush and fluffy. I gave 4 stars because there were some spots on the form that took 3hours to fully expand. I timed it. And some spots that didn’t fully expand to its normal form look. Overall I am satisfied and I hope it helps with my man back!
