  • Fit's size prefectly
Color: White Size: Full
I have tried numerous mattress covers and until this one I have been disappointed. It fits snug on the mattress so it will stay put. I am so pleased with it that I'm going to order one for each bed.

  • Good Enough
Color: White Size: Queen
This is pretty much what I was looking for, a pumped up mattress cover. I do wish the 2" were true. Maybe it is before you lie on it, but I doubt it. I'd still buy again. My bed was stiff as a board.

Color: White Size: California King
Whew.. I almost bought a new mattress but tried this first. Yes.. it softens an old hard mattress.

  • Ok at first.....
Color: White Size: King
I have had this now for awhile now, 10 months to be exact. At first it was great....but over time I have noticed it is getting a dip on both sides where we sleep. Disappointed it has not held its shape. It does come with a guarantee, but sending back a mattress may be difficult, so I have not looked into it yet. Right now I am still sleeping good, if that changes I will consider sending back. ... show more
