In the worldwide, left hand crowd accounts for 10%-12% of the sum of the population. However, in the life, there are no many articles that are considered for these special populations. This results that the left hand crowd often encounter various products that is not conductive to their habit. It is very inconvenient. For example, traditional seat with pallets has the problem that left hand could not use it. Left and right chair could ensure the seat bracket is free to rotate to the left or right through clever back rotating structure. This is not only suitable for the normal people, but also very easy for left hand person to use.
