Choosing an Adjustable Ergonomic Kneeling Chair
Before purchasing an ergonomic kneeling chair, consider that people differ greatly in height and one size does not fit all.
In the U.
S.
, the bulk of adult males are between a height of 5'5" and 6'2", a considerable range.
That being considered, to design a piece of furniture made for one size and assume that it would be ergonomically suitable for everyone is a fallacy.
Purchasing a chair with adjustable parts is absolutely necessary for both ergonomic alignment and comfort.
Ergonomics is a well defined science.
With a traditional 90 degree chair, the necessary adjustments to achieve health ergonomics is simple to achieve.
The base of the seat is raised in order to level the eyes with the monitor's midline.
The arms rests are adjusted such that the upper arms drop straight down and the forearms extend forward at a 90 degree angle to rest on the desk or keyboard tray.
With an ergonomic kneeling chair, ergonomics is more easily achieved, especially with the natural vertical spinal alignment that they provide.
However, the most important factor to consider when selecting chair is comfort.
Only an adjustable ergonomic kneeling chair will be able to achieve comfort for all body types.
The shin pad supports the weight of the lower body.
It should have an adjustable tilt angle.
The tilt affects compression between the calves and the thighs.
Squishing the calves and thighs together can be uncomfortable if one is not used to it.
Relaxing the angle of the shin tilt will provide relief for this scenario.
The base of the seat should also be adjustable in its angle.
The seat angle effects the hip flexors, the front muscles of the hips.
A traditional chair supports a 90 degree angle which tends to tilt the pelvis forward, and can attribute to chronic lower back pain.
Increasing this angle relaxes this muscular tension, which is one of the main functions of an ergonomic kneeing chair.
However, in this setup, the shins will bear a portion of the weight.
A comfortable balance should be found between the angle of the upper and lower halves of the body and the comfort of the shin pressure.
Some ergonomic kneeling chairs have sacrum supports.
These are small back-rests that rest up against the lower portion of the spine.
Support at the base of the spine can help with vertical alignment, however the design of a kneeling chair should already facilitate this.
To ensure that the sacrum support does not get in the way if not needed, it's position should be adjustable.
Lastly the vertical height of the ergonomic kneeling chair should be adjustable.
Since kneeling chairs typically do not have arm rests, the chair should be raised such that the lower arms are horizontal and in-line with the keyboard.
The monitor can then be adjusted to eye level.
Since adjustable kneeling chairs have more moving parts than stationary chairs, be sure to consider the materials of your chair.
Steel or iron are low cost and provide the stability to provide a long life for your ergonomic kneeling chair.
