The invention relates to a rotary seat which comprises a seat body and a rotary base. The rotary base comprises a fixed plate, a rotary plate and rotary plate bearings. The rotary plate bearings comprise the inner bearing and the outer bearing, a hollow mechanism is arranged in the middle of the inner bearing, the inner bearing is horizontally and rotationally arranged in the outer bearing, the outer bearing is fixedly disposed on the fixed plate, the rotary plate is fixedly connected with the inner bearing, and the seat body is fixedly arranged on the rotary plate. The rotary plate bearings have the advantages of being compact in structure and capable of bearing large axial loads, radial loads, overturning moment and other comprehensive loads. The rotary plate bearings drive the rotary plate so that the rotary plate can rotate more stably, wires penetrate through and are connected to the seat form the middle of the inner bearing, the wires can rotate along with the seat, rotation is more flexible, and the wires are prevented from being wound on the seat.
