Problems of Ergonomic Chair:
Ergonomic chair : Probable Risks(3)
It is very uncomfortable for the user to sit in a seat pan that is inappropriately sized. It fails to give enough support to the legs and restrict the whole body movements of the user. Shorter ones place more pressure on the buttocks of the taller users and longer ones place more pressure on the knees of the shorter users minimizing the back support. One that is too small can restrict movement and provide inadequate support. Prolonged use can restrict blood flow to the legs and create irritation and pain.
Feasible Solutions
-
The depth of the seat pan of the Ergonomic Chair should be adjustable to support taller users adequately simultaneously allowing shorter users to sit with full support to their back. The Ergonomic Chair should also provide support for most of the thigh without contact between the back of the user's knee and the front edge of the seat pan.
-
Always use a footrest, which elevates the knee slightly to relieve pressure on the back of the leg.
Use a Ergonomics Chair that is sized to fit small or large users. This is very important if multiple users share the Ergonomic Chairs.
