Once you've made the decision to replace your traditional office chair with a more ergonomic one, you want to be sure you get the right one to best suit your needs. Ergonomic chairs are designed to create good support, comfort and to also promote better posture. The trick is finding one that is comfortable and useful at the same time. Here are a few of the most popular styles to choose from:

Kneeling ergonomic chair.

The kneeling has no back, the user is put in a modified kneeling position while seated. This unique design encourages good posture by sliding the hips forward and properly aligning the back, shoulder and neck. By distributing the weight between the pelvis and the knees, spinal compression is reduced which also reduces the stress and tension in the lower back and leg muscles.

Saddle ergonomic chair.

The saddle chair is another ergonomic chair that can be used as a desk chair or computer chair. It is shaped like a horse's saddle and puts the user in a position somewhere between sitting and standing which allows the legs to drop naturally, and widen, creating a healthy and stable position. People with lower back problems find this type of chair most comfortable.

Exercise ball ergonomic chair.

The exercise ball chair is a completely different type of ergonomic chair featuring a ball large enough to support the user for long periods of time and is great as a desk or computer station chair. Its main advantage is the way it encourages movement by slightly bouncing the worker and keeping the legs moving, which stimulates circulation and keeps muscles busy, reducing stress and fatigue. It's hard to slouch when sitting on this type of ball-chair so lower back strain is eliminated.

Recliner chair.

People with pain from lumbar spinal stenos is or degenerative disc disease often feel most comfortable in a reclined position with their feet propped up on a footrest. This type of chair works well for them. Swivel tables and laptops can be installed onto the chair to make working easier.

An important thing to remember is that no chair, even an ergonomic one, can keep a person from becoming stiff and sore if they refuse to take regularly stretching breaks to improve circulation. Getting up from time to time will encourage stronger posture, relieve strain on the eyes, and reduce fatigue. That, in combination with a good ergonomic chair can help eliminate many of the discomforts of working at a desk all day.
