There are so many things wrong with this design.
The screws for the houses do not hold the houses tight, they just hold the houses in place...not good when one of the houses is on a second level.
The color is not beige, it's a beautiful mellow yellow, I LOVE this color, BUT, the fake  fur sheds...it needed brushed with a lint brush before I even attempted to finish the assembly....my tee shirt is covered with pale yellow fuzz due to the shedding of the fake fur.
Good usual instructions....unless you are missing parts or a post , which was the case here.
I love Wayfair, so, it is not their fault, it is the manufacturer's fault for this faulty design.
I highly recommend pulling this design from the shelves, a cat will get hurt sooner or later due to the wobbly construction and short screws.
Very cat friendly, my cats want to play on it , but, I will put it away till I can finish it..can't now, because of missing parts.
