I believe every mattress should be covered with a mattress pad. It's like underwear for your bed. That being said, this padded cover is just great. Wouldn't have expected anything less. One tiny error, on my own part, is that I didn't check to see if the sides were elasticized, They were not, but no prob. Fits over my 10" memory foam mattress with eggcrate topper over that (all bought from Wayfair). I'm am a happy, happy woman to have such a comfy bed that is wearing underwear (mattress topper, in case I went way off the subject.....squirrel...ADHD kicking in, sorry) Now I'm just waiting for the bed frame. It's hard to get off the mattress when it's on the floor.
