Is it possible to buy this type of piano?
There are quite a few variations of that floor piano for sale, yes.
@digitalimpression Way Cool! Good link.
Sure. You can get it right from FAO Schwartz, the store in the movie.
Someone just gave my daughter one a few weeks ago. She got it in NYC – not FAO Schwartz but I’ll find out where – another big store. We love it. It records, too, and plays a bunch of instruments besides piano.
I just looked at the box and it’s called The World’s Biggest Piano Mat and it’s made by Smart Planet.
The ones they have at fao schwartz are a bit smaller but are basically the same
I should have added that the one I received as a gift was the one linked by @digitalimpression from Amazon.
