Ultimate Test For Fit – The Office Chair
Finding an office chair that properly fits an individual in every aspect can be a tough task considering most chairs are designed to fit what many manufacturers consider to be the norm, individuals that are 5’5″-5’10″ and weigh less than 250 po
s. Unfortunately that leaves many sitting in a chair that does not fit them correctly or a chair that can not support their weight, especially when a business standardizes one chair model for their entire office. Even worse, a chair that is not properly fitted to the individual can lead to work related health issues such as back pain, lumbar pain, shoulder pain, neck pain, and other aches and nuisances. If you do not have an ergonomist on hand, which most companies do not, the perfect fit chair can be achieved with a little research. When researching potential chairs it is essential to take a look at all of the features and adjustments the chair comes with.
Users should be able to sit with their feet comfortably on the floor or on a footrest without pressure on the underside of the thighs. The thigh-to-torso angle should not be less than 90°.
Users should be able to sit in the chair without undue pressure against the back of the knees, their back properly supported by the backrest and with adequate thigh and leg support.
Seat Pan Angle
This should allow users to support their feet on the floor or footrest. This should not cause the user’s torso-to-thigh angle to be less than 90°. Forward seat pan angles should not cause users to shift excessive weight to their feet or experience the sensation of sliding out of the chair.
The seat should be wider than the hip breadth of the user with allowance for movement and clothing. The seat width should not limit the ability to use the armrests comfortably.
All backrests should provide adequate lumbar support and backside clearance. For tasks requiring upper body mobility, the backrest should not interfere with the user’s movement; a mid or low back chair is would be recommend. For users who prefer reclining postures or greater upper back support, the back height should be tall enough to provide support for the shoulder blades.
The width of the backrest should provide adequate support for the curvature of the user’s back without causing localized pressure points.
The height and shape of the lumbar support should coincide with the lumbar curve of the user’s back. The support should be firm, but not cause localized pressure points. An adjustable backrest often helps the user achieve the correct positioning.
This should allow users to sit in a variety of postures while supporting their forearms and/or elbows in a manner that avoids lifting the shoulders, this often results from armrests that are positioned too high, or leaning to the side to reach the armrest, this results from armrests that are positioned too low. The armrest height should allow accessibility to, and performance of, tasks.
The length of the armrest should allow users to sit close enough to the work surface to perform their tasks while maintaining contact with the backrest.
Inside Distance Between Armrests
Armrests should allow users to sit in a variety of postures while supporting their forearms in a manner that avoids lifting the shoulders and/or excessive outward positioning of the elbows. Armrests should allow accessibility to, and performance of tasks. The inside distance between the armrests should allow the user to enter and exit the chair easily. The hips should comfortably fit between the armrests or supports.
