Convention is if it has arms/surrounds you you sit in it, if not you sit on it. So you sit in an armchair but on a kitchen chair. Most wheelchairs have arms on both sides so you sit in them unless there are no arms. HTH.
Offence is in the eyes of the recipient I know but while “wheelchair bound”, “confined to a wheelchair” etc are absolute no-no’s, “in a wheelchair” is widely used in the wheelchair user community, their representative organisations, the NHS, Government etc. A quick Google image search for wheelchair shows that the vast majority have arms. If I offended you, I apologise
Yes it is very widely used and no offence is intended. I just think wheelchair user is much nicer way to say it. Just my personal opinion but I appreciate what you have said.
