Metrex Mesh chair from costco is my pick. Comfortable, supportive and sturdy. Leans back nicely without being too loose or can be locked in place. It swivels and arm rest height is adjustable and swings back for easy entry/exit. I find mesh more comfortable than traditional padding since theres nothing hard underneath. Costco charges $110 online but in store I've seen it on sale for as low as $70.
