The school desk-chairs are one-size fits all desks, in which both the petite 5' and tall 6'8" students must both fit, despite the obvious discomfort. The entire unit is welded in place, so there is no space for students to adjust to their size. Some student's feet hardly touch the ground, whiles others knees are jammed into the bottom of the desk. It decreases the circulation to the legs and positions the back in a constant slouch, making the chair very uncomfortable. The somatosensory cortex senses this discomfort and cues fidgeting to overcome postural strain, which is then distracting from the subject's work.
In blinding contrast, there is a chair that is so well designed, it has earned a place in the Museum of Modern Art's permanent collection. This chair, the Aeron chair, pays particular attention to the ergonomic needs of a desk chair, as well as the environmental. With nine different points of adjustment in the chair, it is capable of fitting each and every body type, while positioning the spine and pelvis in the anatomically correct position for maximum comfort and support.
The chair's main website demonstrates the versatility of the chair according to your specific needs. The Aeron chair ensures the customer has a comfortable seating position and alleviates back pain. The absence of fidgeting and discomfort allows one to focus and complete their work without pain. That is, if you want to pay over $600 for a chair.
