We were looking for a small changing mat with two wedges, as we only have a small baby changing mat. The changing mat is really great, it is not just foam, but has at the bottom a kind of board, which means it is very stable and "wabbelt" not rum. With still 4 parts are supplied (one for each corner) for fixing, if you want to attach the backing properly and secured on a slippery surface. As others have mentioned embroiders the support really, if one opens, but airing after one day the smell is completely gone. Since we still have some time for its "grand entrance", we left it any longer simply stand outside. Damage it will certainly not. What so as icing on the cake still happens, I find, is the "bar" on the page.
