I’ve had this tree a while and it’s sturdy, fairly easy to put together, and my cats enjoy it.  The only bad thing about it was the greenery was a total waste bc my fat cat kept eating it so I had to to just throw it away.  But after several years of use, it’s still looking pretty much the same as it did when I opened it.  As long you vacuum it or even just give it a quick sweep now and then it stays looking pretty nice.
