Harrison Spinks Salisbury 10750 EU King Mattress

Cover
An in-house woven, chemical free Belgian damask cover, which means the sleeping surface stays breathable rather than trapping heat. It's a natural fabric rather than a synthetic knit.

Comfort fillings (top side)
Layers of Egyptian cotton, white British wool and mohair, responsibly sourced from Harrison Spinks' Yorkshire farm. These fibres wick moisture, which means a drier, more temperature-stable feel through the night.

Micro and Micro HD springs
Springs small enough to behave like a foam, targeting pressure points with accuracy. They sit above the main pocket spring system to soften the initial feel.

Cortec™ Pocket Springs
Individually pocketed springs developed by in-house engineers, which means each spring moves independently and adapts as you change position through the night. This is the supportive core of the mattress.

Micro and Micro HD springs
A second layer of micro springs beneath the pocket spring system, mirroring the layer above. This sandwich construction is what makes the mattress fully double-sided.

Comfort fillings (bottom side)
The same Egyptian cotton, British wool and mohair fillings repeated on the underside. You can flip the mattress and sleep on either face, which helps the fillings settle evenly over time.
