This is a great bit of kit that is very easy to set up, it only took me about 20 minutes. The cats seem to love it, jumping all over it. It is over 5feet tall too - my mainecoon loves sitting on the very top spot and staring down at me from a great height. Just a few words of caution:
If you have laminate flooring, it isn't as sturdy as you might have hoped - BUT it doesn't and hasn't fallen over - I actually think the odd wobble is great for their balance, and my mainecoon is a big boy, so if this was going to fall over or collapse, it would have done so by now!
Now this is the biggie - please check the material lining of the fur on the MDF bases - My boy has been to th vets as he had ingested a length of "spray on glue" that was left as dangling, as a manufacture left over. It was clear, thin and stretchy, and i pulled it from his mouth (about 8" of it) and yet he is still ill and is having to go back for another "expensive" trip to the vets....
I imagin this is a one off, but please be vigilant and check and double check the quality of finish on your purchase. If there are any stray threads, remove them, before your inqusitive kitty ingests them :-(
