This is a very nice cat condo.  I got it for my large senior cat so she can easily climb up.  She is being a little stubborn on using it but the times I've placed her on top she's stayed and enjoyed the view.  It was easy to assemble and comes with the tools and the price was really good.  The only minus is it shakes a little when my cat is on it.  She is though, in all fairness, a big girl.  For a smaller cat it might not sway as much.  It is a very nice looking design and my girl loves batting the ball on the coil.
