摘要： To realize a noble, useful seat with a simple structure designed to follow a natural movement of a seated person in front-rear and left-right directions and to support appropriately a movement of the person continuously changing its posture while the person balances a load. The seat includes the elastic support layer 3 and upper and lower base units 4 and 5 arranged to sandwich the elastic support layer 3. The upper base unit 4 includes the rolling surface 42e bulging toward the lower base unit 5 thereabove via the elastic support layer 3, is rollable in a 360° direction from the tilt reference position IRP in receiving a load of the seated person, and has a moving distal end side tilting more downward as a distance from the position IRP increases, and is configured to move while compressing the elastic support layer 3 by the rolling surface.

摘要： In view of various movement of a seated person, when giving the left-right swinging operation to the seat in the non-conventional aspect, a chair configured such that the back can perform a new movement suitable for the left-right movement of the seat and return to the predetermined position when the seated person leaves a seat, is realized.
For the purpose, a back 6 is arranged behind a seat 5, and the back 6 has an operation mechanism 6M turning-movably supporting the load received from a seated person in a left-right direction in a front view, and when the load is applied, at least a part of guide part 65a, 66a of the operation mechanism 6M is separated and the back moves freely, and when the applied load is removed, the back automatically returns to the neutral position along the guide part 65a, 66a.-
