pillow

Abstract

This product is a pillow comprising a first urethane layer and a second urethane layer, which are two types of urethane layers with different hardness, and two core materials. The two core materials are positioned between the first and second urethane layers, respectively, and extend along the longitudinal direction from the left side to the right side, supporting the user's neck. As shown in the left and right side views, the contact surface between the first and second urethane layers between the two core materials is wavy. As shown in the reference left side view, the proportion occupied by the first urethane layer and the proportion occupied by the second urethane layer in the height direction changes depending on the position in the short direction. This product can be used with both the front and back and top and bottom reversed, allowing the user to select the hardness to support their neck and head.
