I slept like I've never slept before in several years! I'm diabetic and run hot and cold all night! The mattress topper is truly a game changer! I have a mattress with 4 inch memory foam. I usually sleep about 2-3 hours and then awake 2-3 hours! Last night I didn't sweat or get hot! I'm not one to waste money when I'm already comfortable! This topper is life changing! It's quality is outstanding! And a value is priceless if you sleep and don't keep waking up! It fits my queen bed perfectly. No odor! I love my topper and never knew it would be a game changer!

Feels soft to hand

This is a mattress cover with deep pocket as the description while i selected this was so confusing where it was referred as mattress topper as well. As a mattress cover yes it have that deep pocket and fits nice on my 14" mattress. It does feels soft to hand but thickness is not that great to add further comfort to the level to feel it.
