We have a Medline wheelchair for sale. The chair is very clean, was barely used and has very strong breaks. The leg rest have various tilt and length adjustments in addition to padding for your calves.
The seat is a 16 inch wide version so not meant for anyone with a larger or bottom. The chair can support up to 200 pounds but probably best for someone 175 or less because of the width of the seat.
The narrower chair is very advantageous for having to use in the house as it fits through doorways easily
