Do you wake up with a heavy, tired feeling in your lower back? The Kobuki BUJI high-resilience mattress solves such problems from the root. We use high-grade springs, SWRH72B, which exceed domestic JIS standards. Instead of the usual 1.8mm, the main body uses 2.0mm, and the longest outer rows are thickened to 2.2mm. These pocket coils provide strong support for turning over, offering a firm feel without bottoming out. Even those concerned about back pain or body pressure distribution can sleep soundly through the night in a natural posture. With high durability that withstands 100,000 rolling tests, it prevents sinking and sagging after months of use. We've reinforced edge support in all sizes, from single to queen. This extra-thick 23cm mattress ensures a comfortable sleep for a long time.
