Method

Admission. A chair enters this index only if its manufacturer publishes a weight of 65 lb or less, about the ceiling for one person lifting a powered chair into a vehicle. Heavy-duty and rehab chairs are outside this index's scope.

Ranking

Order is by stated weight, lightest first; ties break to the higher quality score. Weight basis (with/without battery, frame only, heaviest piece) is printed on every line — we never silently convert one maker's basis into another's.

Quality scores

The 0–10 score beside each chair is computed on a fixed method from manufacturer documents and owner ratings: Performance 40, Accountability 25, Satisfaction 20, Value 15. No maker pays to be listed, and no weight or score is adjusted for any maker.
