This is a premium line [SI] semi-double hard type mattress from the Nishikawa Air brand, favored by Major League Baseball player Shohei Ohtani, Japan national soccer team player Takefusa Kubo, and Japan national badminton team player Nozomi Okuhara.

Semi-double size / Floor type / Developed for daily self-care, this is the [Air SI] mattress with a special three-dimensional cross-slit structure.

I suffered from lower back pain for many years, and the pain upon waking up was severe. However, since using the Air SI, my lower back pain has significantly eased. I am selling this item because I am considering upgrading from a semi-double to a double size. It comes with a storage case.
