Decide what you want first - armrests or no armrests? Mesh or fabric or leather? Do you want it on wheels or no wheels? I like having the armrests that go up when I am at the machine, yet come down when I am just sitting at the machine ripping out a seam or pinning a seam. I like to be able to use them to push off when getting up after sitting for a long time. It is an office chair and bought from Costco, it had to be put together (which my daughter did for me). It gets warm in So.Cal. so I wanted a mesh chair. I am 5'8" and overweight and 68 years old. So that may also give you an idea why I chose what I did. My sewing room is carpeted, so I also put a chair mat down so I could use a rolling chair and not have it get full of thread and carpet material.
