Drawing on the vast, enigmatic beauty of the Caspian Sea, the Caspian mattress blends natural comfort with quiet strength. Like the world’s largest inland sea – rich in biodiversity, culture, and contrast – this mattress is crafted with responsibly sourced fibres and precision-engineered springs to deliver deep, balanced support. It’s a sleep experience shaped by nature, heritage, and a vision for a more sustainable future.

The Caspian collection offers a full spectrum of support options — from gentle, medium and firm, to a dedicated ortho support — each designed to provide deeply personalised comfort.

At the heart of the mattress lies our innovative 13750 spring system, combining Cortec™ Quad pocket springs with dual layers of HD 3000, HD 2500 micro springs, and Posturfil pocket springs. This multi-tiered spring design ensures outstanding support, pressure relief and body-contouring comfort across all tensions.

Luxurious natural layers include a British wool & viscose blend, a British wool & hemp blend, and a cotton & flax blend, with the Caspian Ortho further enhanced by an additional layer of our homegrown hemp for a firmer, more supportive feel.

Finished with three rows of side stitching and a 25cm border depth, each Caspian mattress is expertly handcrafted to deliver comfort, resilience, and the exceptional quality you’d expect from Harrison Spinks.
