How to choose an ergonomic office chair
Choosing an office chair that supports your posture can help to prevent back, neck and wrist injuries and maximize your function at work. To find the right ergonomic chair, you will need to know the various characteristics of the ergonomic chair and how it may support your needs. Choose an ergonomic office chair using the following steps.
Height – An ergonomic chair should allow for adjustment in height to allow you to sit comfortably with your feet flat on the floor, with your knees at a 90 degree angle and parallel to your hips.
Armrest – Armrests can support your arms so that your shoulders rest at a comfortable position when you are working. This is an important feature if you are typing at the computer for a large portion of your day. Armrests should be adjustable in height and position to accommodate different users and activities.
Back – The backrest on an ergonomic chair should support the natural curve of your spine, providing support in the lower back. It should be high enough to support your shoulder and neck region, while allowing for flex and movement for reaching activities when you are sitting. Some ergonomic chairs have a recline function in their back rest to allow for reclined sitting, which is when the hip to back angle is greater than 90 degrees.
Seat – An ergonomic chair should provide comfortable support to your hips and buttocks and the seat depth should measure from your back to 2 to 4 inches (5.1 to 10.2 cm) from the back of your knees.
Headrest – A headrest allows your head to be supported when you are sitting in a reclined position in your chair. This is a useful feature if you spend more time sitting in a reclined position for talking on the phone than typing at your desk.
