Stainless steel solid lges and frames
We use two layers of solid steel to make the legs and the whole stand instead of hollow steel. Using sold steel to make the chair heavy while hard to break down at least for 5 years. Some manufacturers uses hollow steel thus the cost can be half, but this hollow steel leg will be broken within 1 year if not less. We use two layers of the steel, first layer-the flat iron inside, and second layer- stainless steel outside to wrap, which makes the frame very strong.
