Abstract
An air-conditioned mattress includes a mat device, a cover device, and an air-conditioning device. The mat device includes a first mat configured as a three-dimensional structure made from a plurality of elastic thermoplastic filaments that are randomly tangled with each other. The thermoplastic filaments are fixedly connected at contact portions of the thermoplastic filaments in a way that through holes are formed at non-contact portions of the thermoplastic filaments. The cover device covers the mat device and contacts the top surface of the first mat, and the first mat is more air-permeable than the cover device. The air-conditioning device is disposed inside or outside the mat device and provides heated air flow or cooled air flow into the first mat.
