Sandwiched between luxurious layers of wool, cotton and polyester, the Crystal boasts an impressively high spring count that's perfect for those who want a quality firm support.

Upholstered in a durable damask cover, this premium mattress benefits from a hand tufted finish that's designed to ensure the generous layers of fillings are held securely in place.

The foundation of the mattress is made up of small diameter pocket springs, tightly nestled together with each one housed in its own cloth sleeve, freeing them from any neighbouring spring.

The load on one spring is not affected by any surrounding springs, allowing them to contour perfectly to your body shape and provide piston-like support to each part of the sleepers’ body.

Pocket springs are totally independent and are not affected by varying weights and body shapes, resulting in a spring system that supports directly at the point of contact.

Manufactured with support and longevity in mind, the Crystal is a highly specified double mattress that's sure to offer a superior night's sleep.

Technical Specifications 



Hand tufted

Ensures fillings stay in place and increases the life of the mattress. Especially important for extra deep mattresses.

Luxury Belgian damask

Traditional hard wearing and durable cover in a timeless woven design.

3000 pocket springs               (in a standard king size)

Pocket springs are individual independent springs that offer the most sensitive and supportive spring system currently available today.

Hand side stitching

A labour intensive process that sews the pocket springs to the mattress border. It provides total edge to edge support and prevents the side panels from bowing out. 

Firm support

The most popular level of support that suits all but the heaviest or lightest of people. The majority of our customers choose this support level.
