Office Chair (Hickory St. & Breezehill Av S)

Looking for a more supportive office chair ( taller back, better lumbar, softer seat etc)
It doesn't have to be perfect, just needs to roll.
Currently using a very small, very basic hard one to get around my living area - I am nursing a broken leg & waiting for surgery. A rolling chair has been a helpful idea to get to the bathroom & at least not sit in bed all day!
Happy to even just borrow one & return it after a few weeks!
Located near Preston/Carling. We are able to drive and pick up
