High backed chairs

Everyone knows that having a good supportive chair will help the back, posture and general health of anyone, but what makes a good chair?

Different sources will provide you with different answers, but most will highlight a number of features, paramount of which is a good high backrest.

A backrest can have a number of features. On an office, ergonomic or task chair it needs to be adjustable because the person using it will be working. This means that they will be in a partially prone position with their arms out in front of them and their head probably tilted towards a monitor or display of some kind.

When this is the case the back needs to be supported as much as possible and although the lower lumbar region is critical the higher regions of the back can also gain from some support.

These chairs will often have levers and dials that allow adjustments in anything from angle and height to the inflation of an air pocket to create a bolstering effect in the backrest’s lower sector.

With an easy chair a high backrest becomes much more important. Here the full length of the back is normally relaxed back into the padded backrest and this results in the top of the back, and even the head, being supported by the chair.

In the case of older people the high backrest not only provides comfort and good support, it will additionally make the process of sitting down and standing up easier and more relaxing. Features and examples of high backed easy chairs are different to regular chairs.

Of course the backrest is just one component of a good chair and the seat, frame and armrests contribute significantly.

Attributes like seat height change, seat angle, seat depth and a waterfall seat are important for office chairs and having a higher than average seat level will help when it comes to easy chairs for the elderly.
