This activity mat Tomy Disney Winnie is superb. Everything is well thought out but it's true that the carpet take up much space. Personally I installed it on a futon mattress because directly on the ground is not comfortable on a bed that's too dangerous. Because even the tiny baby sometimes rolls. The only point to note is that the batteries are not included. Well the same time it is not essential electronic melody on a play mat. This is a purchase that I recommend.
