I am very disappointed with this item.  It had to be assembled with an Allen key.  The base is too small for the height.  All the joints have to be tightened every day as it gets wobbly.  It also tips easily unless secured to a wall.  My final disappointment is the "carpet" covering the perches.  It is thin towel material.  Although very pretty to look at, stay away from this line of products.  Since my purchase these items have been decreased by 50%.  This tells me that Wayfair is aware of the inferiority of this product.  If you love your cat, go out and buy one of those ugly, heavy cat trees with real carpet.
