Vercelli is 160 cm on a 49 × 41 cm base, with posts shaped as cactus stems — a tower designed to look like something rather than to look like a cat tree.
A rim 15 cm deep
The top perch is 30 cm across with a rim half again as tall as the usual 8 or 10 cm. That changes how it is used: at 15 cm a cat lying in it is genuinely enclosed on all sides, closer to a bed than a platform, which is what a nervous cat wants at height.
Raised edges on the jumping platforms too
The upper platform measures about 49 × 31 cm and the lower one 31 × 31 cm, both with lips along the edges. On a tower where cats land from above, an edge is the difference between a stop and a slide.
A target to scratch
The sisal board is cut as a target — concentric rings that give a cat a visual point to aim at. It sounds decorative, and it partly is, but a board a cat notices is a board a cat uses.
A basket that turns and a condo below
The hanging basket, about 32 cm across, rotates as a cat steps into it. The condo measures 31 × 31 × 30 cm with a 21 × 22 cm entrance.
Pom-poms that unclip
Two, with bells, and removable — so they can come off when a cat starts eating them, or be replaced when they are destroyed. Most towers glue theirs on.
Five kilos per tier
That is the figure, given per level rather than as a total. Moppy and plush fabric over an engineered-wood frame, with sponge padding, 11.5 kg assembled.
