The Harrison Spinks Sapphire 20000 Mattress is a premium British-made pocket sprung mattress combining an impressive 20,000 innovative springs with luxurious layers of natural and responsibly sourced fillings, including British wool, mohair, hemp, flax and cotton.

Part of the Harrison Spinks Seasonal Turn collection, the Sapphire features two specially designed sleeping surfaces. A wool-rich Warm Side provides natural insulation during the cooler months, while a cotton-rich Cool Side creates a fresher, breathable sleeping surface for warmer weather.

At the heart of the Sapphire is an advanced combination of Cortec™ Quad pocket springs, HD 4000 Micro springs and HD 3000 Micro springs. Multiple spring layers work together to respond independently to pressure and movement, providing highly responsive support and precise contouring throughout the mattress.

Available in Soft, Medium or Firm tension, with split-tension options available in selected sizes, the Sapphire 20000 is an excellent choice for customers looking for a sophisticated natural mattress with a high spring count and luxurious handcrafted construction.

What is the Harrison Spinks Sapphire 20000 Mattress?

The Harrison Spinks Sapphire is a luxury natural pocket sprung mattress designed for sleepers looking for a sophisticated combination of responsive spring technology, natural comfort fillings and seasonal temperature regulation.

Inside the mattress are 20,000 springs, including Harrison Spinks' Cortec™ Quad pocket spring system and multiple layers of smaller HD Micro springs.

The different spring layers are designed to work together. The main pocket spring system provides the supportive core of the mattress, while thousands of smaller micro springs add increasingly precise contouring closer to the sleeping surfaces.

The Sapphire combines this sophisticated spring system with layers of natural materials including British wool, mohair, hemp, flax and cotton, creating a luxurious mattress without relying on thick layers of conventional foam for comfort.

20,000 Springs for Advanced Responsive Support

The Harrison Spinks Sapphire incorporates a total of 20,000 springs, making it one of the more sophisticated mattresses within the Harrison Spinks Seasonal Turn collection.

Its spring system combines three important Harrison Spinks technologies.

Cortec™ Quad Pocket Springs

Cortec™ Quad pocket springs form the supportive core of the Sapphire mattress.

Each spring can respond independently as pressure is applied, allowing different areas of the mattress to adapt to the shape, weight and movement of the sleeper.

This independent response provides targeted support while also helping to reduce the transfer of movement across the mattress when compared with traditional interconnected spring systems.

HD 4000 Micro Springs

Layers of smaller HD 4000 Micro springs add another level of responsive support within the mattress.

These compact springs respond individually to changes in pressure, helping the mattress contour more precisely around the sleeper.

HD 3000 Micro Springs

The Sapphire also incorporates multiple layers of HD 3000 Micro springs.

These additional micro spring layers provide further cushioning and contouring above and below the central support system, helping create the responsive and luxurious feel of the Sapphire.

Together, the Cortec™ Quad, HD 4000 and HD 3000 spring systems create the sophisticated 20,000-spring construction found within the Harrison Spinks Sapphire.

Natural British Wool, Mohair, Hemp, Flax and Cotton

The Sapphire combines its advanced spring system with carefully selected natural comfort fillings.

Its upholstery layers include:

British Wool & Viscose

Naturally breathable British wool helps regulate temperature and manage moisture while providing resilient cushioning.

British Wool & Mohair

The Sapphire introduces a luxurious blend of British wool and mohair.

Mohair is a naturally resilient and breathable fibre that complements the temperature-regulating properties of wool while adding another premium natural material to the mattress's comfort layers.

British Wool, Hemp & Flax

A blend of British wool with hemp and flax provides additional natural cushioning, resilience and breathability.

Cotton, Hemp & Flax

Breathable plant-based fibres help create a fresher sleeping environment and play an important role in the Sapphire's summer sleeping surface.

Together, these materials provide natural cushioning around the mattress's thousands of responsive springs.

Seasonal Turn – Warm Side / Cool Side

The Harrison Spinks Sapphire 20000 is a Seasonal Turn mattress, meaning it has two different sleeping surfaces designed to complement different times of the year.

Warm Side – Winter

The winter side places a wool blend close to the sleeping surface.

Wool is naturally insulating while remaining breathable, helping create a comfortable sleeping environment during cooler autumn and winter nights.

Cool Side – Summer

The summer side places a cotton blend close to the sleeping surface.

Cotton is naturally breathable and helps manage heat and moisture, providing a fresher sleeping surface during warmer spring and summer nights.

Turn the mattress seasonally so that the appropriate sleeping surface is uppermost.

Choose Your Mattress Tension

The Harrison Spinks Sapphire 20000 is available in:

Soft – provides a more yielding sleeping surface with increased cushioning and contouring.

Medium – balances cushioning with support and is suitable for sleepers who prefer a feel between soft and firm.

Firm – provides a more supportive and less yielding sleeping surface for those who prefer a firmer mattress feel.

Mattress tension is a personal preference and shouldn't be chosen solely according to sleeping position. Your body weight, build, current mattress and preferred sleeping feel should also be considered.

If you're unsure which Harrison Spinks mattress tension is right for you, contact our team for advice.

Split Tension Options

Selected sizes of the Harrison Spinks Sapphire 20000 are available with split mattress tensions.

Split tension allows each side of the mattress to have a different feel, making it particularly useful for couples who have different comfort preferences or body weights.

Depending on your selected mattress size, available combinations can include:

• Soft / Medium
• Medium / Firm
• Soft / Firm on selected Zip & Link configurations

Please select your required mattress size above to see the available tension combinations.

Chemical Treatment-Free Mattress Cover

The Sapphire is finished with Harrison Spinks' in-house woven FR chemical treatment-free mattress cover, complementing the natural materials used throughout its construction.

The mattress is finished with four rows of traditional side stitching.

Side stitching is a traditional bed-making technique used around the mattress border, helping secure the border construction while contributing to the premium handcrafted appearance expected from a luxury Harrison Spinks mattress.

Due to the substantial spring system and natural fillings, we recommend having assistance when turning or moving the mattress.

Is the Harrison Spinks Sapphire 20000 Right for Me?

The Sapphire is particularly suited to customers looking for:

• A premium Harrison Spinks natural mattress
• A sophisticated 20,000-spring support system
• Cortec™ Quad and multiple HD Micro spring layers
• Natural fillings rather than a predominantly foam-based construction
• British wool and luxurious mohair
• Hemp, flax and cotton comfort layers
• Seasonal Warm Side / Cool Side comfort
• A mattress designed to be turned seasonally
• Soft, Medium or Firm tension options
• Split tensions in selected sizes
• Highly responsive pocket spring support
• A luxury British-made mattress

Harrison Spinks Sapphire vs Ruby

The Harrison Spinks Sapphire 20000 sits above the Harrison Spinks Ruby 12500 within the Seasonal Turn collection.

Both mattresses combine Harrison Spinks pocket spring technology with layers of natural fillings and feature Warm Side / Cool Side Seasonal Turn construction.

The biggest difference is the spring system.

The Ruby contains 12,500 springs, using Cortec™ Quad, HD 2500 Micro and Posturfil pocket springs.

The Sapphire increases the total spring count to 20,000, combining Cortec™ Quad springs with HD 4000 and HD 3000 Micro spring layers for a more sophisticated micro-spring construction.

The Sapphire also introduces a luxurious British wool and mohair blend and is finished with four rows of side stitching, compared with three rows on the Ruby.

If you like the natural materials and Seasonal Turn design of the Ruby but want to move further up the Harrison Spinks collection with a significantly higher spring count and additional natural luxury, the Sapphire 20000 is the natural next step.

Pairing the Sapphire with a Harrison Spinks Divan Base

The Harrison Spinks Sapphire 20000 can be paired with a suitable bed frame or divan base.

For a complete Harrison Spinks sleep system, consider pairing the Sapphire with a Harrison Spinks divan base.

A Padded Top divan base provides a stable and supportive foundation, while a True Edge pocket sprung divan base adds another responsive spring system beneath the mattress.

For a mattress at the level of the Sapphire, a pocket-sprung Harrison Spinks base is worth considering if you prefer a more responsive complete-bed feel.

Harrison Spinks divan bases are available separately in a range of styles, fabrics and configurations.

How to Turn the Harrison Spinks Sapphire

As the Sapphire is a Seasonal Turn mattress, it requires both turning and rotating.

During the initial settlement period, follow the Harrison Spinks mattress care instructions supplied with your mattress.

After the initial settlement period, Harrison Spinks recommends rotating a Seasonal Turn mattress regularly and turning it twice a year so that the appropriate Warm or Cool sleeping surface is being used.

The change between spring/summer and autumn/winter provides a useful reminder to turn your mattress.

Because the Sapphire can weigh up to approximately 96kg depending on size, assistance is recommended when turning or rotating larger mattresses.
