Arona is 206 cm tall — in a room with standard ceilings, that puts the top bed above head height — on a 60 × 50 cm base. Seven levels sit between the floor and the top, so the climb is made of short steps rather than long jumps.
Two condos, and one of them has two doors
The lower condo measures 48 × 30 × 28.5 cm with a 17 cm round opening cut through its roof and a 20 × 23 cm side entrance. That second door is worth more than it sounds: in a two-cat household, a box with one entrance becomes a place one cat can corner another, while two openings mean there is always a way out. The upper condo is round, 30 cm across and 30 cm high, with an 18 × 23 cm entrance.
Four ways to lie down, at four heights
A bolstered bed crowns the tower — 33.5 cm across with a 10 cm rim, 28 cm of usable floor inside it. Below, a large hammock of 50 × 45 cm and a smaller round one of 35 cm. Then flat platforms of 30 × 48 cm and two of 60 × 40 cm, wide enough for a cat to lie stretched out rather than curled.
Sisal posts, 6 cm thick
Post diameter is the detail most listings leave out, and it decides whether a cat can dig in without the post flexing. Six centimetres is substantial. A separate 30 × 20 cm scratching board handles flat scratching.
Read the load figure before you buy
The maximum is 20 kg for the whole structure, not per platform — a modest figure for a tower this size. Arona suits one or two cats of ordinary weight rather than three large ones piling on at once. The frame is particle board under a plush covering, with PP cotton padding.
Fix it to the wall
An anti-tip kit is supplied and wall anchoring is required, not optional. At 206 cm with a 60 × 50 cm footprint, the tower is tall relative to its base — use the kit.
