Seventy inches is tall enough that an anti-tipping kit is not optional, and one is supplied to strap the frame to a wall. Three sleeping options are built in: a 19 x 10.5 x 3 in coffin bed, a castle condo measuring 19 x 10 x 10 in inside, and a 12 x 9 in basket bed, all lined in plush over sponge padding. A dual-entry house means a nervous cat is never cornered by a housemate. Sisal posts take the claws that would otherwise find the sofa. The base is 20 x 20 in, each tier holds 22 lbs, and the tower weighs 36.5 lbs.
