Coverage per dollar

The reformer supports the widest range of the classical repertoire of any single apparatus, and almost every taught program assumes access to one. If you buy one machine, this is it.

The chair is more specialized. Its repertoire is smaller but not lesser — it is unusually good at standing work, unilateral loading and upper-body pressing, all of which the reformer handles less directly.

Footprint tells a different story

A chair occupies about 2 ft square against the reformer’s 8 ft × 2 ft 3 in plus clearance. If your constraint is genuinely space rather than money, a chair may be the only serious apparatus that fits — and it is a demanding one.

For very small rooms, a chair plus a good mat covers more ground than most people expect.
