I bought the Visco-pad for my lot to firm mattress and I regret it a bit. In specialized stores you pay to zu400, - !!!! for as a part. I was really glad to have been able to find on Amazon. Initially, the expectations were for correspondingly low, but this changed with receipt of the goods immediately. Really great quality. Relieves the joints immediately after the first night. Can finally sleep through the night and wake up in the morning and recovered painless on :-) delivery was super fast! Thanks :-)
