Individually pocketed springs reduce noise and motion transfer, making it well suited for light sleepers.

  • ENHANCED SAFETY & EXTENDED LIFESPAN Reinforced with robust edge support to minimize sagging and improve stability, the Sleepmax Starry mattress enhances safety by reducing the risk of rolling off during nighttime movement. The strengthened edges also protect the internal structure, helping extend the mattress's overall lifespan.
