The Sleep Shop Trio MEDIUM Pocket Adjustable Mattress is designed for adjustable beds, providing medium tension support with pocket springs and Cloud Lite foam technology.

The core comprises small-diameter pocket springs, each enclosed in its own cloth sleeve for complete independence. This setup enables precise contouring to body shape, piston-like support to individual areas, balanced weight distribution and reduced motion transfer for undisturbed partner sleep.

Cloud Lite foam layers deliver a lighter sensation than conventional foam, with equivalent durability and significantly lower heat retention compared to memory foam, resulting in a more breathable and comfortable sleep surface.

The mattress is covered in a soft, luxurious stretch-knit fabric that stays pliable, allowing the internal comfort layers to conform closely to body contours.

Key Features

  • Medium tension — Balanced support that contours effectively to the body. Suitable for combination sleepers who alternate between side and back positions.
  • Cloud Lite foam — Innovative foam offering a lighter feel than standard options, with maintained durability and minimal heat retention compared to memory foam.
  • Pocket springs — Individually encased springs that adapt precisely to body shape and isolate movement to minimise partner disturbance.
  • Flexible edge support — Edges constructed to flex reliably with adjustable bed mechanisms without losing shape or support.
  • Quilted finish — Stitching secures the outer fabric to the comfort layers, creating a smooth and consistent sleeping surface.
  • Stretch knit fabric — Soft, pliable cover that moves with the fillings to ensure optimal contact and support.
  • Single-sided design — Rotate head-to-toe periodically for even wear; no flipping required.
  • Turning handles — Reinforced handles on the border to simplify rotation.
  • 1-year guarantee — Covers the mattress and base against manufacturing faults with free repair or replacement in the first year.
  • VAT exemption — Available for those with a recognised long-term illness (standard VAT applies otherwise).
