I used this as our first play gym — the mat is nicely padded and super soft, and the toy arch detaches and folds back so baby can kick the colorful piano keys. The piano lights up and plays music when pressed, all four keys work and the hanging toys clip on/off easily. It’s been washed and stored with batteries removed, there are only light creases from storage and no stains or odors. Great for tummy time and for encouraging kicking and reaching.
