I am so happy, took me 20 minutes to unwrap it (you like bubble wrap don't you?), 5 minutes to put it up, 30 seconds for the girls to find it, can't get them off it now.
It's incredibly stable, there's about 12kg of cat on it at the moment and it just doesn't move
Really, really pleased.
THANKYOU so much for your help in its design, I'm going to start expansion plans now

(As you can see, my photographic skills are about as good as my drawings, I was going to do a sketch of it for you, but my wife's hid my crayon again.)
