My kid loves this gym mat with a keyboard that makes a noise so I bought him this mat when he was outgrowing a kids gym mat. This stimulates the child's response when touching the keyboard. It is soft and has no chemical smell. My boy could spend about half an hour playing it, either play it alone or just press the demo button and leave the sound on. A bit noisy but my son loves it. We even take it to the backyard during quarantine when we need some fresh air.
