Experience exceptional comfort, innovative spring technology and traditional British craftsmanship with the Harrison Spinks Sapphire 20000 Mattress. Designed to deliver a luxurious sleeping experience, this premium mattress combines an impressive 20,000 pocket springs, sumptuous natural fillings and a unique dual-season design to provide outstanding comfort and support throughout the year.

Featuring a split-tension construction with medium and firm comfort options, the Sapphire 20000 is ideal for couples who have different sleeping preferences but want to enjoy the same luxurious mattress.

20,000 Pocket Springs for Exceptional Support

At the heart of the Sapphire 20000 is an impressive 20,000 pocket spring system, designed to provide highly responsive, individualised support throughout the night.

Each pocket spring works independently to respond to the natural contours of your body, helping distribute weight evenly and relieve pressure on key areas such as the shoulders, hips and back.

This advanced spring construction also helps minimise motion transfer between sleeping partners, allowing each person to enjoy personalised support without unnecessary disturbance.

Split-Tension Medium & Firm Comfort

The Sapphire 20000 features an innovative split-tension design, offering medium comfort on one side and firm comfort on the other.

This allows sleeping partners to enjoy different levels of support within the same mattress, without compromising on individual comfort.

The medium side provides a balanced combination of gentle cushioning and responsive support, while the firm side offers a more supportive sleeping surface for those who prefer a firmer feel.

Dual-Season Comfort with Natural Fillings

Designed for year-round comfort, the Sapphire 20000 features a dual-season mattress construction, offering different sleeping surfaces tailored to the changing seasons.

The winter sleeping surface incorporates warmer fillings to provide a cosy and comfortable feel during colder nights, while the summer surface is designed to encourage breathability and moisture management in warmer weather.

Combined with luxurious natural fillings, this seasonal construction helps create a comfortable sleeping environment throughout the year.

Natural fibres provide soft, supportive cushioning while offering excellent breathability and moisture-wicking properties, helping regulate temperature and maintain a fresh sleeping surface.

Enhanced Edge Support & Traditional Side Stitching

The Sapphire 20000 incorporates enhanced edge support, providing additional stability around the perimeter of the mattress.

This helps reduce the sensation of rolling towards the edge while creating a more consistent and supportive sleeping surface.

Traditional side stitching further enhances the mattress’s construction by securing and supporting its borders, helping maintain the structure and shape of the mattress over time.

These carefully considered finishing details reflect Harrison Spinks’ commitment to quality craftsmanship and dependable comfort.

Turnable Design for Lasting Performance

The Sapphire 20000 features a traditional turnable mattress design, allowing you to enjoy the benefits of its dual-season sleeping surfaces.

Turning the mattress between seasons helps you select the most suitable sleeping surface for the time of year, while regular turning and rotation encourage even settlement of the natural fillings.

This practical design helps maintain the mattress’s comfort and performance, supporting a consistently comfortable sleeping experience.

Available as part of the Prestige Beds clearance collection, with delivery in just 1–2 weeks, the Harrison Spinks Sapphire 20000 Mattress combines advanced pocket spring technology, luxurious natural materials and traditional craftsmanship for exceptional year-round comfort.
