This chair is the worst I have ever bought. The threads on the hole and screws are very coarse making it very hard to assemble. The screws are coated with blue threadlocker but it never cures. The screws are constantly loosening and need retightening. Everything about this chair has been an absolute pain. It is gone now and so is my business.
I recently moved my office equipment to my dining room table since I needed more solace than my current desk. As a result I was sitting all day in an uncomfortable dining room chair. I have recently purchased the Sorina leather chair and couldn’t be happier. The chair is quite comfortable love the wheels to slide from side to side and most important no more backaches.
