Gray plush over an engineered wood frame, 58 in of vertical space and a 22 x 18 in base that keeps the whole thing from rocking when a cat lands hard on the top perch. That perch measures 14 x 14 x 3.5 in with padding thick enough to sink into; below it sit a hammock, several stepped platforms and an 11.5 x 11.5 x 10 in condo. Sisal wrapping on the posts gives claws somewhere to go other than the sofa. The tower weighs 29 lbs and ships flat with an instruction sheet for assembly.
