Crema is 132 cm on a 55 × 44 cm base, and it carries something none of the other towers here have: a grooming brush fixed to one of the posts.
The brush post
Cats groom themselves against edges — door frames, table legs, your shins. A brush mounted at cat height turns that habit into something useful: loose hair comes off on the tower rather than on the sofa, and it happens without anyone having to catch the cat and hold it still. For a long-haired cat, or one that hates being brushed, it earns its place.
Posts 7 cm thick
That is substantial — most posts are 5 or 6 cm. A thicker post does not flex when a cat digs in and pulls, which is what makes the difference between a post that gets used and one that gets ignored. Two of them, plus a separate flat scratching pad for cats that prefer to scratch horizontally.
Four levels
Three platforms — 55.5 × 44 cm in the middle, 24 × 44 cm at the bottom, 33.5 × 30 cm above — a cat house of 33.5 × 30 × 30 cm with an arched 16 × 19 cm doorway, and a top bed measuring 50 × 32 cm outside and 40 × 26 cm inside.
Six kilos per cat, 12 kg in total
Those two figures fit exactly two average cats and no more. Crema is a one- or two-cat tower; for a household of three or a single very large animal, look at a heavier model.
