I am very impressed with the excellent customer service and the quality of the tree. It is really stable and even the attached platforms do not shift the weight unequally if a 10kg Maine Coon is sitting on them.
The issue is that the cats find it somewhat difficult to get to the top platform. The box in the middle has rather small holes and my bigger cats will not use them. They would want a platform sticking out at the bottom level, so that they can push off of that. As it is, I had to order some bookshelves to place near the tree so that the cats will be able climb it. For now, I have to help them or they use the windowsill to get up.
The tree is quite narrow for so many attributes, for example I immediately removed the slide in the middle - if the tree is intended for big cats, how can you expect them to squeeze through that little hole? Also, my Maine coon would like to lounge at the top platform, not only the hammock or the bed - BUT there is a hole there, so he is just confused.
When they want to get down, it can get dangerous - they will not use the hole, which is the only option really, so then they will jump from the highest platform to the ground. Thankfully, I have a bed in front of the tree, so they can use it for landing.
5 stars for quality, but was expecting better design, definitely less squeezed together :(
