My goodness was this super easy to put together. It came with easy to follow instructions. It’s made of good quality materials. It is very sturdy and it is safe for my cats to climb on. My cats simply adore this new home. I love the little beds that came with it, it is just enough cushion. My cats are constantly in it now and I’m super happy with this product. Don’t hesitate, it’s a wonderful addition for any cats.
