Most: Very nice and good size, as are the small hanging toys. The carpet underneath is machine washable at 30 ° C and dry in 2 hours max. The rest (ark, toys ...) is surface washable with a sponge. Note: the fabric of the carpet is not waterproof.
Cons: Difficult to transport: disassembly is not practical and no transportation / storage bag is provided. It is also a bit expensive for a product that contains no mechanism or electronics.
