my cat Emily loves this tree so much! It is very large and leaves space for her on the platforms! She’s a bit heavy for a female cat and gets scared when her platform wobbles and this is definitely sturdy enough for her! It was fairly easy to put together, didn’t take more than an hour, and so far this tree has stayed looking like new for the last year (with an occasional vacuuming). The sisal posts are still looking good too! I couldn’t recommend it more!
