The lower pet bed had a sharp tack, staple or nail sticking out on the front edge as the kitty would climb into the shelf/bed. Dangerous and could put an eye out, cut a paw or skin of your kitty or your hand. Also, the Carpeting is thin..skimped and could have used thicker carpeting. I would NOT recommend ..the height was good, not too tall to avoid fall injuries.  I would also recommend the lower tier bed to stick out a little more to give your kitty a better step down and or up to the next level. Biggest issue and return was sharp nail or what ever on the edge of the pet bed. Dangerous. WayFair isncustomer focused and returned/refunded purchase.
