Last place in this guide at #10, and the most expensive chair in it. The CAP Strength Hyperextension Roman Chair is a steel-framed back extension bench with foam padding, built for core and lower back training at home. The listing price is £331.64 and the page carries 4.4 out of 5 from 374 ratings. It stands 18.6 kg on its own and states a 300-pound maximum user capacity.

The headline and the spec field underneath it do not agree on size. The bullet-style description gives the chair as 57.87 x 27.56 x 34.65 inches; the dimensions field further down reads 373D x 177.8W x 224H centimetres. A 57.87-inch footprint is about 147 cm, not 373 — the centimetre figures behave like the inch numbers pushed through a 2.54 conversion twice, which is exactly the kind of gap between one line and the next that runs through these listings. Everything below is taken from the Amazon listing; we have not tested this chair ourselves.
