Two. The Winn 202 L has an attendant brake, so a carer can control the chair from the push handles — useful on slopes and in crowds. The Winn 203 L has 20" rear wheels with a propelling ring, so the user can self-propel independently.

Yes. Aluminium is lighter without giving up strength, and both models support up to 100 kg — the same as our steel standard chairs. Aluminium also does not rust, which helps in humid and coastal areas.

They are the range to choose for travel. Both fold, the backrest flips down, and the footrest is detachable and height-adjustable, so the chair packs into a car boot easily. If you fly, check your airline's rules for wheelchairs before you travel.

Both use canvas upholstery with antimicrobial and fire-retardant treatment and include a seat cushion — breathable for long sitting, and treated for hygiene in daily care.

They cost more than a steel standard chair, because aluminium is the more expensive material. Aluminium models also carry a 12-month warranty against 6 months on mild-steel frames. If lifting the chair regularly is part of your day, most people find it worth the difference.
