The best ergonomic chair for you is the one that fits your body well and most important is comfortable for all the hours you sit in it each day.
Please realize no office chair is going to be the right choice for everybody. People who are taller or larger than average may need a big & tall chair. The petite person will find a much more comfortable fit in a petite chair. We can fit a chair to anyone from 3' to 7' tall, and up to 800 lbs.
Most people do not need a headrest but many prefer a chair with a headrest. We carry hundreds of ergonomic office chairs including many not visible on this website. Please give us a call if you don't see what you want, or wish help selecting the best office chair. We can also help you outfit an entire office with chairs that look alike but fit different bodies and purposes.
