Seat depth is one of the first things to look for in an ergonomic chair. When buying an ergonomic chair, you need to make sure that you can adjust the seat to a comfortable level, with a slight distance between the knees and the floor. This way, you can rest your feet comfortably without reaching for a footrest. You may also want to consider a chair with an adjustable headrest, which can relieve tension on your shoulders and back.
The next consideration is durability. An ergonomic chair must be comfortable and durable and allow for easy movement and rotation, which will help you maintain a healthy posture and promote better blood flow. The wheels should also be sturdy, with at least five spokes. High-quality wheels will prevent damage to the floor and keep you from buying a new chair every few months. Furthermore, the chair should have the right weight capacity to accommodate the person using it.
