Top marks, but some caveats
The tree arrived in a timely manner with simple instructions and ... no screws. To be fair to Zooplus they resolved the matter to my satisfaction within a few hours of me emailing them. So fair play to them for that.
For the money, this is a really nice, tall, thin tree which I've positioned behind my reclining chair in the lounge, between lounge and dinning room. I've sited the round 'den' just behind and above my head. My cat loves climbing up the chair (and me) to get to his vantage point!
I dispensed with the hammock because I knew my cat would ignore it and I didn't use one of the rope-covered pole sections as it made it too tall for where I wanted it to go. But the options with this tree are great. I'm only using the padded screw adjustment bracket at the top (with added large washers and bolt to distribute the load and stop the large screw bending) and it's a solid as a rock. Were the top buttressing against a plasterboard ceiling I would *definitely* recommend using the supplied wall bracket, but since the tree is positioned between wooden floor and solid lintel I'm satisfied that it's not moving anywhere (and I do check on a regular basis).
A fellow reviewer commented on the limitations of the supplied velcro holding the beds in place: I agree there probably isn't enough. So forewarned -- thank you -- I added more white velcro strips and staple-gunned all of them to the wooden platforms, including the one in the den. Another reviewer commented on the lack of velcro supplied with the beds themselves: there isn't any. It foxed me for a moment, but you need to turn the beds inside out -- i.e the upper surface of the beds, as supplied to me, will stick against the velcro on the platforms perfectly once they are on the bottom of bed. :-)
I'd have no hesitation in recommending this cat tree at all.
