Hi, I have Cerebral Palsy Diaplegia and have worked in an office environment for many years full time 35 hours a week I sit on an ordinary office chair which is absolutely fine. During a conversation with my physio today she asked if I used an ordinary office chair as she thought that perhaps I would be more comfortable on a chair with a saddle like shape to it so that my hips would be in a better position. I.e. not rotated inwards. (Does this make any sense)?? My question to you is are there any office chairs out there with a saddle like construction or that would promote a good posture for people with CP?
