This is a semi-double spring mattress.

Only used for about 1 month as it didn't suit me.
It was covered with a sheet, so there was no direct contact.

■High-quality Bonnel coils that reduce body strain
?Bonnel coils are all connected, lifting areas prone to pressure like the waist to prevent sinking, supporting the entire body as a surface for a stable sleeping experience.
?Unlike pocket coils, they are not wrapped in non-woven fabric, which makes them highly breathable.

■Thick 20cm for firm support
?With ample thickness, cushioning is enhanced, further reducing the feeling of hitting the bottom!

■Highly elastic knit fabric
?The elastic knit fabric conforms to your body for a more comfortable sleep.

■Breathable 3D mesh fabric on the sides
?The entire side is made of 3D mesh, efficiently releasing moisture and maintaining a comfortable sleep.

■Voluminous quilting for improved comfort
?Features moderate cushioning to reduce the feeling of coils against the body, plus voluminous quilting that retains moisture. Finished for a soft and comfortable sleep.

■Formaldehyde-free specifications
?This mattress has undergone quality testing by a leading quality control organization in Japan. The test results proved that the formaldehyde content is 0.00ppm.

Thank you.

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.
