This is a high-rebound mattress with a firm sleeping comfort made of highly elastic urethane foam. It features a unique Honeycomb Pillar Processing that reduces shoulder strain when sleeping on your side and allows for smooth turning. Furthermore, the firmness varies by area, reducing sinking in the waist.
The Air Free is particularly excellent in its body pressure distribution when sleeping on your side, smooth turning, and variable firmness that reduces sinking in the waist, making it recommended for those concerned about ease of turning and sinking in the waist.

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.

Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.

Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.

Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
