Comfort

I let it expand for 48 hrs. It took its proper form . I have to say Im very impressed by the quality. Very comfortable .

Worth the money

We are really loving this topper.  We purchased it to go above the mattress on an adjustable hospital-type bed, which was stiff and uncomfortable.  What a difference!  Definitely recommend this topper.

Excellent purchase!

I like it very much,its soft enough to sleep on,
