Review on 21''X 16'' Sagging Couch Support Under Cushion Sofa Seat Saver Fordable Board by Ryan Cornelius

I didn't know what to expect or how supportive the seat saver board would be, and to my delight and comfort my sofa and sectional has a new life again. The firmness when sitting or laying down is remarkable, the problem I now have is getting up from the sofa who want to leave such comfort. :)
