Unparalleled sleep comfort and support combine in the Nautica™ Energize Medium Firm Hybrid Mattress, featuring a 12-inch height and zip-off, machine-washable cover. Arriving conveniently compressed and directly to your door— this hybrid innerspring mattress-in-a-box utilizes a soft knit surface, 2-inches of body-contouring memory foam, and 2-inches of pressure-reliving engineered latex foam for bounce-back resilience. Minimizing motion transfer and offering targeted support, the tri-zoned pocketed coil system includes heavier-gauge springs for lumbar reinforcement and thicker-gauge springs at both sides.

  • Removable Cover: Zip-off soft knit fabric cover is machine washable to ensure a clean, hygienic sleep surface. The zip-off top can be removed independently from the bottom of the cover.
  • Contouring Memory Foam: 2" pressure-sensitive memory foam molds to your body and helps to increase circulation with gentle, targeted support and returns to its original shape as soon as the pressure is removed.
  • Engineered Latex Foam: 2" high-resilience comfort foam offers extra contouring support for pressure-free comfort.
  • Tri-Zoned Pocketed Springs: 7" independent fabric-wrapped springs offer consistent support distribution and help minimize motion transfer and partner disturbances. Heavier gauge springs in the lumbar area provide extra back support.
