Love this tree. It is sturdy but we did have to redo a few bits to tighten it up, it’s a process of trial and error. The instructions made me laugh, it’s basically a picture of the whole thing assembled and labels of which piece is named what rather than step by step on how to do it, having said that it is quite easy to do and we had fun assembling it. Our kitten really enjoys climbing it and loves the mice. She is not quite brave enough to go all the way to the top! Really great value for money I would recommend or buy from this brand again.
