I use an Ottobock wheelchair with e-fix. The back and leg supports are fixed and my wheelchair guy wants me to upgrade - my posture is bad when sitting. The first one I tried is a Karma wheelchair - really nice - suspension , reclining back and leg supports - you can also raise the seat. Now he has the idea to try the Meyra iChair Sky - this can raise you into an upright position- very hi-tec! Does anyone have any experience of this chair? I am not sure how my body will react to this - I have to use a lift to get me in and out of the chair. It would be great if you are able to get the trousers up and down.
