The most popular overlay in our range, this convoluted "egg carton" overlay / topper is made from soft, strong premium quality foam. This overlay / topper is thicker than most of its competition, with a 60/30mm convoluted profile. It will add comfort to most any mattress, and especially relieves aches and pains caused by hard sleeping surfaces.
In our opinion this is one of the best foam overlays available, and is great value for money too. No wonder we sell so many! Note also that this quality foam overlay will extend the service life of any mattress by many years. Inner-spring mattresses have a top layer of foam that flattens with use over time. By doing the work of this foam layer Foam Sales' overlay will extend your mattress' service life.
