Firm Orthopaedic Support
Designed for maximum spinal alignment and pressure relief. The Ruby 12,500 offers a firmer tension with precision-targeted spring zones and resilient natural fillings — ideal for those who need extra support without sacrificing breathable comfort.

The Ruby 12,500 Orthopaedic mattress is one of the most advanced models in the Harrison Spinks collection — expertly handcrafted for deep, restorative support and sustainable luxury.

At its foundation is a Cortec™ Quad Pocket Spring system, layered with Posturfil and HD 2500 Micro Springs. Together, they create a responsive, contouring structure that evenly distributes body weight while minimising movement transfer.

Natural fibres including British wool, hemp, flax, viscose, and cotton surround the spring system — selected for their breathability, temperature control, and durability. The mattress also features a Seasonal Turn design:

• Wool side for winter (warm and insulating)

• Cotton side for summer (cool and moisture-wicking)

The 3 rows of hand side-stitching reinforce the edges for better durability and full-width sleeping comfort. It’s all wrapped in an FR chemical-free woven cover, safe for sensitive skin and the planet.

👤 Who’s It Best For?

• People needing firmer orthopaedic support for back, hip, or joint concerns

• Hot and cold sleepers who benefit from a seasonal mattress

• Customers looking for eco-friendly materials, luxury build, and long-term value
