Also, how is the dentist chairs market divided among the brands? How much share does each one of them have?
The chairs that I am most familiar with are Pelton Crane, KaVo Dental-EZ. I'm not really sure which brands have the largest market share, but I'm sure that if you contact individual companies, they'll know! If you want to purchase a chair, contact your local dental dealer. If you want to work for a company selling chairs, go to the manufacturer's websites.
