Kneeling chairs: are they OK or not?

What are kneeling chairs?

Kneeling chairs are often recommended to those with back problems. Their design forces the user to tilt their pelvis forward which encourages the spine to align into its natural “S” shape and the engagement of back muscles. The user’s knees are supported by fabric pads that prevent the body from sliding too far forward. They generally cost anywhere from £70 to £400. If a GP, osteopath or physiotherapist suggests the use of a kneeling chair, should you consider it?

Are they legal?

The first issue is one of legal compliance. That’s because the Health and Safety (Display Screen Equipment) Regulations 1992 require office chairs to: (1) be height adjustable; (2) have a seat that can adjust in height and tilt; and (3) be stable and allow for a comfortable position. More recent HSE Guidance “Work with display screen equipment” has watered down the need for a back rest for back pain sufferers (see The next step ). Nevertheless, a kneeling chair must be capable of height adjustment.

Is it fully adjustable?

It is this issue of adjustability that can present practical problems as not all kneeling chairs are fully adjustable, e.g. they may only allow for a moderate height adjustment or the tilt of the seat can’t be altered independently. In addition, some are designed with fixed knee rests which may not suit every user.

Tip. Some chairs also have low weight limits so will be unsuitable for heavier users.

Chair still needed

An added problem is that kneeling chairs are often seen as an alternative to normal seating. However, even with practice, most employees won’t be able to use one for a full working day. This is due to a lack of proper support for the body, either through the legs or via a backrest (for those without one). As the individual’s back muscles tire, the user will slouch or lean forward on to the desk to alleviate it.

Tip. To prevent this problem the kneeling chair will need to be swapped with a conventional one at regular intervals throughout the day. So in practical terms, you would need space for two large items of office furniture. If the work area is cramped, this could easily create a trip hazard or other safety issue.

The way forward

Before you make any decision on the kneeling chair, ensure that the employee’s existing conventional chair is set up correctly and not faulty. If this doesn’t help, you aren’t obliged to provide a kneeling chair but you can consider it. Our helpsheet will help avoid the creation of new problems; if you’re in any doubt seek specialist advice (see The next step ).

Tip. A cheaper kneeling chair may an attractive option but is likely to be of inferior quality. Avoid rocking chair designs as they can run over the feet of those who get too close.
