I bought this for my nephews 1st birthday.  My kids had a similar toy and still have it after 8yrs.  Per my sis, he is able to climb up and slide down w/ assist.  The slide is steep enough that he won;t get bored for a while.  She hasn't used the balls, yet.  But I think my nephew will love them, too.  My sis and her husband liked that is was made in the USA.  [...]  Thanks.
