My other mattress pad lost its 'oomp' and was flat, so it's time for a new one. This one looked high and nice, and roomy enough to stay secure beneath the mattress. I unrolled it and placed it on the bed to 'fill itself up' and plump. It needs 24-72 hours to 'plump'. After 3 days sleeping on the couch, I realized the 'plumping' for this particular mattress cover I had bought, was never going to happen. Never really changed from day 1 to day 3. Perhaps this doesn't have enough fill, doesn't look like it, or feel like it. Bottom line: It looks nothing like it does in the ad photo.
