Heights
Moving from standing to sitting, and sitting to standing, is one of the most common tasks
we perform everyday, and usually taken for granted. However, as we get older, it is also
a surprisingly physically challenging task, especially for mobility impaired, elderly, or
arthritis sufferers. Significant clinical research has shown that traditional chairs, with a
typical height of 17”-18”, place significant stress and strain on both the hips and knees.
Extensive research has shown that two simple chair interventions can greatly reduce the
stress placed on the body when moving from sitting to standing positions:
1. Providing arm rests to allow the arms to lift, or support the body when
transitioning from sitting to standing positions.
2. Raising the height of seats to 23”. This height was found to be optimal to reduce
the strain, and increase the efficiency to rise or sit down in a chair several fold.
With the new DecoTeak™ product line our design team incorporated leading ergonomic
research into elegant contemporary designs. Research has shown that the use of arms
when going from a seating to a standing position can decrease the strain on muscles, and
joints and provide up to 300% increased mobility. Almost all of the DecoTeak™ benches
and stools are designed with built in arms to allow customers to conveniently grip the
arms as they lift themselves out of the seats. This also provides added safety in a shower
environment.
Several of our benches and stools are being offered in the Lift Aide™ Extended Height
versions. Clinical research has shown the optimal height of chairs and stools to be 23”.
These extended heights will provide great benefits to the elderly and mobility and
impaired, as well as the general population.
