Folding chairs are a great solution to situations where chairs are necessary but not on a daily basis. For example, a multi-purpose hall in a school could be used for gymnastics displays as well as assemblies, chairs being set out and folded away as and when necessary. In a school environment you will generally find wood used as the preferable material for these chairs, although there are plenty of modern-day alternatives.
The more practical factors that one should consider include features like lumbar adjustment, height adjustment, and the spring tension at which the chair can recline. Good chairs should also come with a latch that prevents the chair from reclining at all. The top quality chairs will provide adjustable armrests. The armrests should be able to be adjusted in and out from the center of the chair, as well as up and down, and even the length of the armrests should be adjustable.
The size of the back of the chair is one of the most important features. For an executive chair to be truly comfortable, the top of the back of the chair should be no lower than the middle of the back of the person's head who will be using the seat. In a truly comfortable office chair, a person should be able to lean back and have their head rest against the back of the chair or a headrest. Many lower quality chairs have backs that extend up almost to the back of a person's head, but not quite. If a person leans back in one of these chairs, their head hangs over the back and it is quite uncomfortable.
