overall this is a wonderful topper. we have had regular mattress toppers in the past....never a foam/gel one. this makes it so you don't want to get out of bed in the morning, and can't wait to get into bed at night. however, the measurements aren't quite what they advertise. the foam/gel topper did indeed measure just about 3"....but the fiber topper is less than a half an inch....a far cry from the advertised 1.5" they claim it to be. so overall it is a very nice topper....i just think that perhaps the price should be lower being as the fiber topper isn't much to scream about.
