In setting up the product -[...]  Then it says it is for 2-8 year olds . . but my son is a big 18 month old and already his head brushes the door frames.  Not sure what an 8 year old would fit in there like ;)  But there are great extras - the phone, the chairs (were they supposed to bolt in?), the tunnels - my son loves it.  Big smiles for him.  Hopefully it last through at least this summer. . . .
