The $150 Granthon leather executive chair boasts adjustable lumbar (lower back) support, soft bonded leather construction, padded arms, molded nylon base, tilt, tension, lock, swivel, and height adjustments.

While this is not a real ergonomic chair, it is an incredibly comfortable chair if your body happens to be of the appropriate size.  That taken into account, for the price, this chair is one incredible bargain.  I have personally purchased chairs of similar comfort and quality for more than twice the price so if you’re in the market for an affordable office chair, this could be the one.
