Mounting to the wall frees the floor entirely, which is the point of this four-level cat climbing set that rises 59 inches without a base taking up a square foot of a small apartment. The arrangement includes a top perch with a 15 by 15 inch cushion, a fabric hammock, two padded platforms measuring 17.5 by 15 and 15 by 15 inches, three scratching posts and a 10.5 by 20 inch scratching mat, so climbing, lounging and claw care all happen on the same wall. Each level carries up to 33 lbs, enough for a large cat to land hard without flexing the plywood. Sisal covers the posts and the mat, giving claws a coarse surface that outlasts fabric. Linen fabric over sponge padding lines the resting surfaces. Installation calls for locating the panel holes against wall studs, and the complete set weighs 30.5 lbs.
