My cats and I love this Cat tree - modern contemporary and a decor enhancement.  Easy to assemble, took 45 minutes after unwrapping packaging (unassisted and not in any way handy type)  by simply following the easy diagram instructions! Even a magnetic tip screwdriver is supplied!  HIGHLY recommend to all cat parents who want an alternative to the carpet shedding trees!  Cats love it, and sometimes scramble for the top shelf  :)
