I may have just imagined it, but the description indicates that this is a foam mattress topper. No, that is not so. This is a cover for a 4 inch foam mattress topper only. The main picture even shows the foam insert. It doesn't say "foam insert not included" anywhere. But I think I should be more aware of descriptions like "Plus, it can be cheaper to upgrade your old mattress topper to a brand new one". If you're looking for a mattress topper and just a cover, give this a try. If you're looking for a gel-foam insert with an attached lid, look elsewhere.
