Are armrests useful in preventing back pain?

Customer: Are Armrests useful in preventing back pain?

C.C. (Colm Campbell): Armrests are extremely important. For two reasons. Firstly, when you are sitting with your elbows properly supported you are taking a considerable amount of weight off your spine and transferring it down your arms. Secondly, in an office situation, when you are keying without armrests, both of your arms are suspended in space and this puts stress on your neck. Keying with proper armrests prevents this stress.
