  • Patent number: 11317602
    Abstract: A pet bed includes a frame body having cushioning properties and a mat surrounded by the frame body and having cushioning properties. The mat has a top surface and a thickness. The frame body has a thickness that is greater than the thickness of the mat. The pet bed has a height in the thickness direction of the mat. The height is greater than the mat at the frame body. The mat has a fiber structure formed of thermoplastic resin fibers having an average fiber diameter of 0.01-5 mm. When the frame body and the mat are compressed under the same pressure, the decrease in the thickness of the mat due to the compression is smaller than the decrease in the thickness of the frame body due to the compression.
