Received it a week sooner than expected that was great.Very sturdy since I have one large cat who could not use the old small one I had,this is perfect! I have three cats total and all can fit on this new one. The big cat loves that top U-shaped piece. I had wondered if that top would be useful and now all the cats want to sit  and nap up there. The scratch posts are thick and durable. Pleased  with this purchase.Easy to assemble.
