る。The moving type is easy to move the whole chair, and the rotating type is easy to rotate the seat, so that there are many opportunities to move the body.
Although it is convenient as a chair for learning, there is a problem that the body is not stable as a chair for a dining table and a meal or the like cannot be performed in a calm mood. Accordingly, stationary chairs are generally used as chairs for dining tables. When sitting on this stationary type of chair and eating, the knees will enter the lower area of the table, so when sitting, sit down at a position lower than the table and then move the chair closer to the table When the person leaves after finishing a meal, an operation for lowering the table back is required. For this reason, especially when a physically handicapped person uses a stationary type chair, it is difficult to perform sitting and leaving operations.
