1. Look for the ability to adjust the chair's height. The height of your ergonomic chair should be fully adjustable. The chair's seat should be easy to move either upwards or downwards. This adjustment will allow for people of different heights to comfortably sit in the chair. Make sure you can adjust how high or low the the seat is before purchasing your chair.
A seat height of 15” to 22” will comfortably seat a person between 5'0" to 6'4" tall.
Most chairs will offer only a small range of adjustment.
Your feet should be able to sit flat on the floor while your knees are bent at ninety degree angles.
2. Consider who will be using the chair. Before you select an ergonomic chair, you'll want to think of who will be using the chair. The chair will need to comfortably fit anyone who will sit in it or be able to be adjusted to fit them. Make sure your chair is a good fit for anyone in your office before making a purchase.
The chair you are interested in should comfortably fit the person it is intended for.
Many ergonomic chairs will be adjustable enough to accommodate most anyone.
3. Make sure elements of the chair can be individually adjusted. A good ergonomic chair will allow you to adjust each part of the chair by itself. You should be able to move the armrests, seat and back supports independently of each other. This level of customization will allow you to make the chair a good fit for anyone that might end up using it.
You may want to avoid chairs that don't allow for adjustments.
Generally, you will want to select chairs that have a large number of adjustable features.
