Our 2.5 y.o. loves the trampoline.  He is always jumping on it.  It has actually improved his two legged jump (use to just walkjump over something wide-legged.  He can hold onto the bars and jump but I can see him growing much bigger and still using it.  The trampoline is the perfect size for starting at age 2.  It was a little difficult to get it put together (hard to pull the trampoline taunt).  But otherwise a great buy.
