Description

Designed to offer you the most comforting, fully supportive night's sleep you've ever experienced, the Spring King® Wool Ortho Pocket Mattress is plumped with gorgeously cushioning materials and a robust pocket spring support system.

Orthopaedic back support to ease pain

The pocket spring system, made up of individually pocketed springs that move independently, is designed to offer adaptable, reactive orthopaedic comfort to your entire body. Moving with you, these springs provide firm pressure relief exactly where you need it, encouraging proper spinal alignment to help ease and prevent back pain. These clever springs also reduce motion transfer, meaning you can turn over in the night as much as you like without disturbing your partner.

Generous layers of foam and natural wool

For sumptuous comfort, layers of body-hugging profiled foam and a natural wool comfort layer add multiple benefits. The specialist foam adapts to your body's warmth, gently moulding to your shape to offer personalised pressure relief. The wool, which is naturally breathable and offers year-round temperature regulation, also contours to your curves, gently applying tension relief at your heaviest points.

A fresher, more rejuvenating night's sleep

The Spring King® Wool Ortho Pocket Mattress is finished with a soft quilted cover, which enhances airflow for a fresher, more hygienic sleeping environment. The anti-slip base keeps the mattress secure on your bed frame, and with an impressive 32cm depth, this mattress is sure to take centre stage in any bedroom.

Features

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.

Pressure-Relieving Profiled Foam

Specially designed profiled foam contours your unique body shape to provide impressive support at every point of contact.

32cm Depth

This mattress is approximately 32cm deep.

Quilted Cover

The quilted cover is created by stitching the mattress cover and the fillings together, creating a patterned comfort quilt layer.

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.

Vacuum Packed & Rolled

Rolled mattresses have the advantage of being easy to transport, especially to upstairs bedrooms. When unrolled, they expand fully over time, usually being comfortable enough to sleep on after 48 hours.

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.

Anti-Slip Base

Prevents your mattress from sliding on your bed frame to ensure undisturbed rest night after night.

Fire Resistant - Low Hazard

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

Benefits

A firmer, orthopaedic feel helps to align your spine to reduce back pain
The pocket springs adapt to your movements for all-night-long support
Natural wool layer regulates temperature and adds a gentle bounce
Profiled comfort foam enhances cushioning while maintaining firm support
32cm deep design makes it ideal for low bed frames or those who enjoy a more substantial mattress
