The Harrison Spinks Sapphire 20000 Mattress is a luxurious Seasonal Turn sleep surface designed for customers who want exceptional comfort, tailored support and premium Yorkshire craftsmanship. Handmade by Harrison Spinks, this mattress combines advanced spring technology with generous natural fillings to create a breathable, supportive and indulgent feel that performs beautifully throughout the year. With an impressive spring count and refined finishing, the Sapphire 20000 is a standout choice for anyone investing in a high-end mattress built for long-lasting comfort.

At the heart of the Sapphire 20000 Mattress is an advanced spring system featuring 20000 springs in a king size. The mattress includes the Cortec™ Quad spring system, an innovative support structure designed to respond accurately to the body for a more tailored sleeping experience. This is partnered with multiple layers of high-density micro springs, including HD 4000 Micro springs and HD 3000 Micro springs. These micro spring layers sit closer to the surface to refine contouring, enhance comfort and encourage airflow through the mattress as you sleep, supporting a fresher and more breathable night.

Comfort is elevated by carefully selected layers of natural fillings, chosen for their softness, resilience and moisture regulation. The Sapphire 20000 includes blended British wool and viscose, a British wool and mohair blend, a British wool, hemp and flax blend, and a cotton, hemp and flax blend. Wool and mohair add a naturally warm, springy feel, helping the mattress remain cosy and supportive, while cotton contributes breathability for a lighter, fresher surface feel. Hemp and flax are highly absorbent fibres that help draw moisture away from the sleeping surface, supporting a cooler, drier and more comfortable sleep environment.

Designed for year-round comfort, the Sapphire 20000 Mattress features a Seasonal Turn construction with a warming wool winter side and a cooling cotton summer side. This seasonal design allows you to rotate and flip the mattress as recommended, encouraging even wear and helping extend the life of the fillings and support layers while giving you a sleep surface better suited to the season.

Finishing details reflect the premium build quality. The mattress features an in-house woven FR chemical treatment-free cover, offering reassurance for those who prefer to avoid added chemical treatments. It is also finished with four rows of side stitching to strengthen the borders, improve edge support and help maintain the mattress structure over time. With a depth of approximately 28 cm, the Sapphire 20000 has a plush, substantial profile that still delivers supportive comfort.

Available in gentle, medium or firm tensions, the Harrison Spinks Sapphire 20000 Mattress offers the flexibility to match personal comfort preferences. It is backed by a five year manufacturer’s guarantee followed by a five year warranty, giving ten years of total cover for added peace of mind.
