Not every chair labeled "ergonomic" has all the adjustment features necessary to truly be ergonomic. This guide will help you make a better selection.Use our chair selector tool and one of our fit experts will respond with personalized recommendations. We love to help people find exactly what works for their needs, and we typically respond within 1 business day.
The mechanism controls how the seat and back move. It includes controls that are typically levers under the seat that the user can push, pull, or twist to adjust the chair. Some models may offer more than one choice of mechanism for the same chair. These two mechanisms are the most popular: Multifunction Mechanism This mechanism is preferred due to the wide range of adjustability it offers. The back and seat angles adjust independently of each other as well as independent of the tilt. This allows you to lock the chair into an infinite number of positions. This type of mechanism will rock/tilt back from the center of the seat. The Neutral Posture NPS800 and the Bodybilt J3507 are two examples of chairs that offer this type of mechanism. Synchro-Tilt Mechanism - The seat and back are linked and tilt simultaneously as you lean back (typically the seat back tilts back two degrees for every one degree of seat pan tilt). Since there is less adjustability with this mechanism it is not as ergonomic as the multifunction mechanism.
A chair with a synchro-tilt mechanism should have a waterfall front or flexible front seat edge or it may press into the back of the thighs when reclining. This type of mechanism also rocks/tilts from the center of the seat. The Raynor Ergohuman and the Allseating Cpod Chair are two examples of chairs that offer this type of mechanism. These are less common but may be appropriate for many applications: Task This is the most basic mechanism and adjustments may be limited to just seat height, seat height plus seat depth, or seat height, seat depth and back angle. Task mechanisms do not offer tilt. As this discourages movement, a task mechanism is best suited for lighter duty such as a home office or conference room. Two examples of this type of chair would be the Ergocentric Saffron Apt and the Raynor Vigor RG33 Task Chair. The backrest should slide up and down to allow the lumbar curve of the chair's back rest to fit into your lower back (lorthotic) curve. A height adjustable lumbar support is a common substitution.
This will also help fit the chair to your body type. Reclining in your chair supports the weight of your upper body and thus relieves some weight from you lower back. Many chairs have a locking back angle adjustment that will let you find your most comfortable reclined or upright position and then lock that position. Both lumbar disc pressure and back muscle activity are lowest with a supported recline angle of 110° - 130°. Reclined postures often are preferred (Grandjean, 1988). This adjustment knob allows you to adjust the amount of force required to recline to your body weight. The Humanscale Freedom Chair and Liberty Chair are counterbalanced to the weight of the user and do not require a tension adjustment. The best lumbar support offers both vertical and depth adjustment. This is especially important if the user has lower back issues, or if multiple people will use the chair. The most basic lumbar supports are adjusted vertically as you raise and lower the chair back.
