An air mattress is a portable mattress made of PVC material, which is inflated for use. It features flexibility and elasticity, and can be easily folded and stored to the size of a pillow, making it suitable for temporary accommodation, outdoor camping, and other scenarios. The surface of the product often undergoes flocking treatment to enhance warmth and breathability, while the interior adopts a honeycomb or drawstring structure design. It is more comfortable to use with a thermal insulation layer in winter, and can be paired with a cooling mat to maintain breathability in summer [1-2].

Its support structure achieves ergonomic design through differentiated inflatable units. For example, the waist and knee areas utilize inflatable channels with larger diameters to provide higher support, while other parts form a curved fit through smaller channels, optimizing lying comfort [2]. Some models are equipped with adjustable inflatable backrests, which can control the tilt angle through independent inflatable tubes. During daily use, excessive inflation should be avoided. After the first inflation, it is necessary to let it sit for 8-12 hours and adjust the air pressure according to the season. If there is a leak, the damaged point can be located using soapy water and repaired with glue of an appropriate material.
