This 12-inch king size mattress in a box is engineered for undisturbed sleep and effortless setup. Featuring an independent pocket spring system and a breathable white knit cover, it delivers targeted body support while isolating motion transfer for couples. The mattress arrives compressed in a compact box, expanding rapidly to full size upon unrolling.

  • King Size Dimensions: Measuring 12 inches thick, this mattress provides substantial support and a plush feel suitable for standard king beds and box springs.
  • Independent Pocket Springs: Each spring is individually encased to contour to your body's curves, absorbing movement so you do not feel your partner tossing or turning during the night.
  • Breathable White Knit Cover: The top layer uses a premium white knitted fabric that is soft against the skin and designed to maximize airflow for a cooler sleep temperature.
  • Eco-Conscious Foam Core: The mattress is layered with high-density, environmentally friendly foam that is free from fiberglass, harsh chemicals, and strong odors.
  • Reinforced Edge Structure: The sides feature a reinforced construction that resists sagging and casual wear to maintain the mattress shape and tailored silhouette over time.
  • Gray Side Paneling: Charcoal-gray side panels with contrasting trim add a modern, understated luxury aesthetic to your bedroom decor.
  • Compressed Delivery: Expertly rolled and vacuum-packed into a compact box for easy transport through tight spaces, hallways, and stairwells.
  • Rapid Expansion: Once unboxed, the mattress expands to its full plush form within hours, allowing for immediate use without long wait times.

By combining compressed delivery with high-density materials, this bed-in-a-box solution removes the hassle of traditional mattress handling and heavy lifting. The independent spring technology ensures that rest is not interrupted by movement, while the chemical-free foam layers create a clean, safe sleeping environment for everyday use. The breathable cover and reinforced edges ensure long-lasting comfort and durability for your home.
