REPORT ON THE KNEELSIT ERGONOMIC CHAIR
This chair presents as an unusual and carefully designed combination chair which includes both a height adjustable backrest and kneeling cushion. The mobility of the chair is facilitated by the attachment of five floor casters to a rigid sleigh shaped metal frame. The upholstery foam and fabric appear to meet chair standards for durability, composition and flammability. The chair moves quietly and it feels solid
After an initial inspection of this chair a few
years ago quality improvements have included a covering of the seat
depth adjustment notches with a swing cover to prevent any injury to
the user or the catching of clothing during use.
b) Chair seat
The seat is also compression adjustable by a
spring mechanism under the seat pan. This mechanism allows for the
accommodation of a range of body weights . Heavy rubber stoppers are
positioned on all components of the chair to prevent metal to metal
impact and to reduce jarring when changing sitting position.
c) Kneeling Cushion
User comfort and convenience
In general, dissatisfaction expressed by users of "kneeling design" chairs has included the lack of back support when the user becomes fatigued. The designer of this chair has made every effort to overcome this disadvantage by adding a lumbar support cushion which is ideally designed and mounted with optimum flexibility.
Difficulties arise when chair design needs to accommodate a broad range of users and this chair has an added constraint over and above the design of conventional, ergonomic chairs which are not directly influenced by the upper leg length of the user. In this chair design every effort has been made to comfortably seat users across a very broad range of anthropometric dimension and to avoid undue forward pressure on the knees.
The options for posture change and lumbar support combined with a sit/kneel position of seating makes this chair design unusual and innovative. Not only would this chair appeal to a general user community but users with mobility disfunction should benefit by its unique design. The appeal of this chair, in a multicultural community like Australia with diverse population anthropometry, should also be applauded.

# This aspect has now been corrected
by the addition of fingerguards.
Who knows best ? - ergonomist or client?
I use a computer all day long, and
have been having back problems for 10+ years. Last summer, my co-worker
went on a 2-month long vacation and I used his chair while he was away.
My back problems were relieved!!
