On recommendation we chose for a topper as a support to our foam mattresses, ordered quickly geliefer with shipping, everything ok. You sleep good at it nice and soft, adapts well to the body. For people who sweat quickly, it is problematic that sweat more, I feel. You have to get used to it, as with any Matrate. If the "old" mattress toppers but the already worn out is good is also not because of Topper nachformt the bumps. In the case with the old mattress contact attempt.
