Though we are extremely pleased with the quality of the product, and the cats absolutely love it, the dimensions listed here are NOT accurate (at least 10 inches off) the numbers given for width and depth refer only to the base of the cat tree and do not account for the numerous platforms which jut out in all directions. as a result, the cat tree does NOT fit in our apartment, a fact that we only discovered after hours of assembly. 

Recommendation: DO buy this product if space and assemble are not a concern for you (its awesome)
DO NOT buy this product if you have limited space and are relying on the given dimensions.
