Description

Harrison Spinks are the creators of truly luxurious mattresses. They're dedicated to creating their products with sustainable, sumptuous fillings, with the Derby 2500 mattress boasting not only a multitude of incredible fillings, but an incredible support system, too.

Expert support with reinforced edges for maximum sleeping surface

Medium firm support with orthopaedic levels of pressure relief, this mattress features an outstanding layer of individually pocketed springs. These springs ingeniously react to your movement and weight placement throughout the night, tailoring their support to your most needed areas.

You'll experience dedicated support to your hips, shoulders and back - you'll even find relief in spinal alignment and posture control, preventing morning aches and stiffness.

Sustainable, natural fillings with a luxury feel

With materials from their 300 acre Yorkshire farm, this Harrison Spinks mattress features layers of comforting flax, cotton and wool.

Acting as a climate control unit, wool traps heat and releases it as you need it, incredibly keeping you at the optimal sleeping temperature. Breathable cotton wicks away excess moisture so you stay cool and comfortable all night long, while flax enhances air circulation for a fresher night's sleep.

These plush layers, combined with supportive, innovative pocket springs, create the ultimate sleeping experience from one of the finest British bed makers.

Features

2500 Pocket Springs

Pocket springs are springs mounted in their own separate fabric pockets, meaning they work completely independently of one another and can provide your body with better pressure relieving support.

Wool

This type of filling gives a soft cushioned feel to the mattress. Wool is ideal for those who prefer their mattress to be traditional and natural.

Flax

An organic, absorbent, light fibre that enhances breathability.

Sustainably Sourced Cotton

Highly breathable, natural cotton fibres provide a fresher, cooler sleep surface, as well as wick away excess moisture. Responsibly sourced, this cotton is grown and harvested by trusted suppliers.

25cm Depth

This mattress is approximately 25cm deep.

Damask Cover

A mattress cover which is made from a breathable Belgian damask fabric.

Orthopaedic Support

Designed to offer a firmer sleep surface, providing targeted support for your back and joints.

Reinforced Edges

The mattress has reinforced edges, so that the full sleep surface can be used. This means more sleeping space - which is usually lost in conventional, less edge-stable mattresses.

No Need To Turn

A single-sided mattress which does not need to be turned/flipped. One-sided mattresses should, however, be rotated head to toe regularly.

No Roll Together

Individual personal sleeping zones mean that you won't be disturbed if your partner rolls or moves, as you won't feel their motion. There's also no tendency to roll towards the middle of the mattress.

Pressure Relieving

This type of mattress gives maximum pressure relief, allowing your body weight to spread across it evenly. This ultimately means less tossing and turning throughout the night and a more relaxing and restful sleep.

Turning Handles

Flag-stitched handles are attached to the sides of the mattress to assist in turning or rotating.

Hypoallergenic

Being hypoallergenic, this is the perfect item for allergy sufferers - or anyone looking for a healthy night's sleep.

Hand Side Stitched

This mattress has been hand stitched on the borders, which creates a firmer edge on pocket sprung mattresses. This is a very expensive process, only done on top quality mattresses.

Hand Tufted

Tufts help to secure the luxury fillings in place, helping the mattress retain it's fullness and plumpness over time.

Made in the UK

This item has been manufactured in the UK.

Fire Resistant - Low Hazard

This product conforms to the BS7177: 2008 standard for domestic use (low hazard) - ideal for use at home.

Additional features

Made by an NBF-Approved ManufacturerPeace of mind and reassurance - the manufacturer of this item is an approved member of the National Bed Federation.
