The Harrison Spinks Ruby 12500 Mattress is a beautifully handcrafted, luxury sleep solution created in Yorkshire by the skilled artisans at Harrison Spinks. Designed for those who want the very best in comfort, support and sustainability, this premium mattress combines an exceptionally high spring count with generous layers of natural fillings. The result is a refined, responsive sleep surface that feels indulgent while delivering reliable, long-lasting performance night after night.

At the heart of the Ruby 12500 Mattress is an advanced spring system featuring an impressive 12500 springs in a king size. Central to this structure is the innovative Cortec™ Quad spring system, which is engineered to provide tailored, body-responsive support. Each spring works independently to respond accurately to movement and weight, helping distribute pressure evenly across the mattress. This targeted support promotes healthy sleep posture while reducing motion transfer, making the Ruby 12500 an excellent choice for couples as well as solo sleepers who value stability and responsiveness.

Enhancing the core spring unit are dual layers of HD 2500 Micro Springs, positioned closer to the surface to add flexibility and refined comfort. These high-density micro springs adapt closely to the body, increasing contouring and pressure relief while helping the mattress maintain its structure over time. In addition, Posturfil pocket springs are incorporated to further enhance responsiveness and adaptability, supporting natural movement and helping the mattress react smoothly as you change position through the night.

Comfort is elevated by a carefully balanced blend of natural fillings, chosen for their breathability, durability and temperature-regulating properties. A British wool and viscose blend creates a breathable, moisture-wicking comfort layer that supports a cooler, fresher sleeping environment. This is complemented by a British wool blend, valued for its soft, springy feel and natural ability to regulate body temperature throughout the seasons. A natural cotton blend adds a plush yet supportive surface feel, enhancing overall comfort while maintaining breathability.

The Ruby 12500 Mattress is designed as a Seasonal Turn model, meaning it should be rotated and flipped regularly to encourage even wear and extend its lifespan. This construction allows the mattress to maintain consistent comfort and support while benefiting from the natural performance of its fillings over time. With a depth of approximately 25 cm, the mattress offers a streamlined yet supportive profile that works well with all bed bases.

Finishing details reflect the quality of craftsmanship throughout. The mattress is completed with an in-house woven cover that is free from FR chemical treatments, supported instead by the natural fire-retardant properties of wool. Three rows of hand side stitching strengthen the mattress borders, improving edge-to-edge support and enhancing durability by keeping internal components securely in place.

The Harrison Spinks Ruby 12500 Mattress is backed by a five year manufacturer’s guarantee followed by a five year warranty, providing a total of ten years of reassurance. Combining award-winning spring innovation with luxurious natural materials, this mattress is an outstanding choice for anyone seeking a truly restorative and sustainable night’s sleep.
