A Distinctive Three-Dimensional Cross-Slit Structure Supporting the Trunk of the Body While Asleep

Supported by points

About 1900 points on the surface support the body and reduce pressure by not obstructing blood circulation. The base area adjusts the body's sinkage for comfortable sleep.

More advanced cushioning

Each block of bumpy structure with 3 x 3 points independently hold the body. It conforms more firmly to the body line and disperses body pressure, allowing smooth turnover and also suitable for side sleeping.

Higher breathability

Vertical and horizontal-crossed slits that promote ventilation of urethane foam quickly dissipate moisture such as humidity and perspiration. With less worries pertaining to drying and dust, it is much easier to care for.

Comparison of Body Pressure Distribution

Using data compiled by a body pressure distribution measuring instrument, the red parts in the lower back indicate a high level of body pressure while at rest.

AiR SI Mattress Reviews

I bought AiR SI in order to get more effective sleep because I don't get a whole lot of quality sleep time. I find it comfortable to sleep on this mattress and I like it.

This mattress supports my body perfectly. I used to back pain, but I mostely forget about it until I lay on my side then I realize it. Originally, I only tried AiR SI with the intention of passing by, but I could not forget it and decied to buy it. It is awesome!
