Choosing a work chair
Your body has evolved to stand upright and be mobile – not to sit at a desk for hours on end. Look for the following features when choosing a home-office chair, and it will be more likely to provide you with long-term comfort:
• A height adjustable seat so that you can rest your feet on the floor, with your thighs parallel to the floor.
• An adjustable seat depth so that your back is supported by the backrest. A seat that is too deep will have you perched on the front. Too shallow, and your thighs will be unsupported.
• An adjustable seat angle. This means that when you lean forward at your desk, the seat will also tilt forward so that your pelvis can maintain a more open position, and your spine can follow its natural curve. The seat should also tilt backwards when you lean back, to vary the pressure on your back and pelvis.
• An adjustable backrest angle. This can be used in conjunction with the adjustable seat angle, so that you can recline away from your desk and rest your back muscles.
• Armrests that are height adjustable so that your arms are supported, taking the strain from your shoulders.
• ...and width adjustable. Armrests at the right width for you will let you keep your upper arms close to your body with your lower arms and wrists in a straight line when using a keyboard or mouse.
• Lumbar support helps to maintain your spine’s natural curve. This is achieved through curves in the backrest, or an extra inserted support.
• Adjustable backrest height so you can set the height of the lumbar support to suit your back.
• A reclining facility allowing the seat and chair back to tilt in a single unit, so that you can vary the pressure on your back and other muscles.
