This really IS like floating on a cloud!  I bought this for a twin bed that is so uncomfortable that you just can't sleep on it.  Several of the reviews were so encouraging that I went for it.  I feel like raving like the others did -- I can't believe I didn't try something like this sooner, and it turned an absolute WASTE OF SPACE into an absolutely delightful night's sleep.  The bed and bedroom even look better because the topper elevated the whole thing.  Try it!  What's the worst thing that can happen, you return it...  I HIGHLY recommend this topper, it's amazing!
