  • 【Cooling & Skin-Friendly】The surface of the TeQsli hybrid spring mattress is made of soft, skin-friendly fabric, allowing people with sensitive skin to easily enjoy a comfortable sleep. The comfort layer of the breathable mattress features multi-molecular gel memory foam, which relieves pressure and helps dissipate heat—keeping you cool, dry, and comfortable all night long.

  • 【Mattress in a Box】Our memory foam pocket spring orthopedic mattresses are compressed, vacuum-sealed, and neatly rolled into a box for easy transport and smooth passage through narrow doorways.

Please allow 24–72 hours for the 150x200cm mattress to fully expand. (Caution: The mattress expands quickly when unrolled, so be sure to keep a safe distance during unpacking.) It is compatible with most bed frames, including box springs, slatted bases, and floor beds.
