We really liked it, my cat climbed right up and took his first cat nap as soon as we put it together it took about 30 minutes to do between me and my son.
It nice and sturdy our cat is on the bigger side 13lbs. 
and he fits nicely.
But the best thing for us is Wayfair’s customer service, every time I’ve needed to deal with anyone there they are by far the best. I would recommend them to anybody.
