Ultra-Light Wheelchairs
Medline K4 Ultra-Light Wheelchairs come in many different styles with different accommodations. The height is adjustable with an adjustable-height back panel and features swing-back arms with an easy flip-back release. The armrests and calf pads are padded and the whole chair is done up in a tough nylon upholstery. The dual axle hemi-height mechanism allows for the height adjustment as well as tool-free removal of the rear wheels for storage or transportation purposes.
Choose from removable desk-length arms, which tuck under desks or tables, or full-length arms that extend to the edge of the seat. Also choose between elevating legrests, which include pads behind the calves to elevate the legs, or the swing-away footrests, which allow the wheelchair to be used more like a standard chair.
If you are looking for an easy-to-clean and maintain wheelchair, you may want to check out the Durable and Easy Cleaning Wheelchairs, which come with vinyl upholstery.
