Features

  • [Softness Levels for Personalized Comfort]: Choosing the right topper can be challenging due to varying firmness definitions among sellers. The cyan memory foam with a rebound force of 50N is perforated to reduce cushioning, enhancing the softness difference, ensuring more ergonomic support that aligns your spine and relieves pressure pointsperfect for back, stomach, and side sleepers.
  • [Effective Body Pressure Relief]: Our topper uses 28D memory foam, which effectively conforms to your body's curves, evenly distributing pressure to improve sleep quality. Infused with cooling gel particles, the memory foam dissipates accumulated body heat, ensuring you enjoy a cool and refreshing night's sleep.
  • [Soft and Breathable Fabric]: The fabric features a recessed knit design that not only adds aesthetic appeal but also enhances breathability, preventing heat buildup. Certified by OEKO-TEX STANDARD 100, the fabric is safe and skin-friendly, providing a gentle touch.
  • [More Features]: Our topper includes a hidden zipper design with a specially crafted cover to conceal the zipper, preventing accidental scratches. Additionally, elastic straps and an anti-slip backing ensure the topper stays securely in place, even as you move during the night.
  • Tips: Leave the Topper flatly in a well ventilated area for 48-72 hours until its fully expanded. Note: Low temperature may need more time, find a suitable temperature(78F) will shorten the time.
