[0005] The purpose and effects of this utility model of a double-layer polyurethane pillow are achieved by the following specific technical means:

[0006] A double-layer polyurethane pillow includes a silicone sleeve; a silicone plate is inserted inside the silicone sleeve, an air bladder is attached to the top of the silicone plate, an inflation nozzle is provided on the left side of the air bladder, and a sealing plug is used to block the inflation nozzle.

[0007] Furthermore, a polyurethane inner layer is sleeved on the outside of the silicone sleeve, and a polyurethane outer layer is sleeved on the outside of the polyurethane inner layer.

[0008] Furthermore, the top surface of the polyurethane inner layer is covered with protrusions in a rectangular array, and the protrusions are hemispherical structures.

[0009] Furthermore, the top of the polyurethane outer layer has a rectangular array of vent holes, which are circular in shape.

[0010] Furthermore, both sides of the silicone sleeve, the inner polyurethane layer, and the outer polyurethane layer are in an open state.

[0011] Furthermore, two first hook and loop fasteners are attached to the bottom of the polyurethane outer layer, and a fixing strap is attached to both the left and right sides of the polyurethane outer layer. A second hook and loop fastener is sewn onto each fixing strap, and the two second hook and loop fasteners are attached to the two first hook and loop fasteners.

[0012] Compared with the prior art, the present invention has the following beneficial effects:
