One of the unusual aspects of a Herman Miller Aeron Chair is definitely its sizing. Aeron Patio chairs are available in three sizes, A, B and C. Size B covers the vast majority of people (around 90%) with 'A' covering the very smallest percentile and 'C' covering the largest, heavier percentile. The positive area of this is that the dimensions for the chair are scaled according to size as is the weight loss for the tilt as well as the chairs are suitable for a much broader choice of people than many other furniture. One negative aspect, and there are not many, is that the chair relies on three sizes for seat more detail. There is no seat depth adjusting facility on the chair. Arm rest height is adjusted to the Aeron Chair via two levers on the rear of each and every arm or, on some chairs, these levers will be replaced by wheels. Hands have a good range of shift and move very easily. Upper arm . pads are pivoting simply because standard, although it is possible to order fixed (non-pivoting) give pads if required. The moment positioned inwards, they offer great support for keyboard work and when positioned straight or perhaps slightly outwards, they are made for mouse or general function. Arm pads are huge and well padded.
