Totter + Tumble’s weightier memory foam means the surface will mould around you, and will seek to support anything on it. Temporary pressure marks from things like knobbly knees, elbows and even play equipment like Pikler triangles, will recover and it’s for this reason we always suggest observing any lasting dents over a few days. As your playmat eases into your home, you'll find it will get quicker at recovering from pressure spots the more you use it. Do keep heavy furniture off them though, unless you are prepared for some long-lasting indentations. You can find more information about looking after your playmat in our Care Guide
