The experience of an uncomfortable chair is not a new
concept and most people are familiar with this situation. On Monday I was
sitting in class for more than 2 hours on a very uncomfortable chair. It was
making my back hurt and I could not concentrate on the subject. I decided to do
some research on how some chairs are comfortable and some are not? What is
significant about the design of a chair that provides a great comfort? And why
people buy uncomfortable chair?
According to an article published on Utah State University,
a seat can be evaluated by the height, depth, width, slant, and contour. One of
the most important aspects of a comfortable chair is the back. The back should
provide support to the shoulders therefore; it has to be high enough. Also, the
slant, which is the angle of the back of the chair, needs to be more than 90
degrees to support the lower back. Furthermore, a slightly curve on the back of
the chair allows the shoulder blades to roll slightly forward. This curve is important;
too much curve will cause damage to the muscles and less curve makes the back
of the chair uncomfortable.
Comparing all these specifications with the chair I was sitting on, I discovered my chair was nothing near a comfortable chair. The back was too short and did not give my shoulders any support. The angle was 90 degrees straight which forced me to seat very straight in an uncomfortable position for long hours. But most of all the very straight back without any curve caused me a back pain that lasted all day.
