How the index works

Product scores come first

Every machine is scored 0–10 from manufacturer documents and owner evidence: Performance 40% (range, power, capacity, weight), Accountability 25% (warranty, returns, published support), Satisfaction 20% (the product's own verified buyer ratings), Value 15% (price against what the spec delivers). These are the same scores published by our sister sites — a chair cannot score one way here and another way there.

The Brand Index

A company's index is the mean of its three best machines' scores. Depth counts: a maker with one great chair and nine weak ones is a specialist, not a leader, and is listed as a specialist. Companies need at least two scored machines for the main sections.

What "Featured" means — the disclosure

Best Mobility Ranking is published alongside 1800Mobility, a mobility retailer. Forcemech is our featured launch company: it receives the first company section and extra coverage depth. That is the whole of the favor. Its index (9.67) is computed like everyone else's — in this edition it also happens to be the highest, earned by three machines scoring 9.7, 9.7 and 9.6. No score, on any site in this portfolio, is ever adjusted for any company, featured or not.
