Description

With a medium feel that keeps you supported no matter the sleeping position you prefer, the Spring King® Wool Luxury Pocket Mattress is ideal for couples, guest rooms, or those who can't commit to one sleeping style!

Impressive support for any sleeping position

The pocket spring support unit within this mattress is cleverly designed to provide full-body pressure relief, with each spring independently adapting to your movements throughout the night. As you move, they target precise support exactly where you need it, helping to keep your shoulders and hips aligned with your spine to reduce back pain. These springs also reduce motion transfer across the mattress surface, meaning you won't disturb your partner with your turning throughout the night!

Body-hugging foam and breathable, natural wool

For deep, sumptuous comfort, a generous layer of profiled foam hugs your body in all the right places. Softening with your body's warmth, this foam gently contours your curves to provide personalised comfort and pressure relief. For added cushioning, a layer of natural wool also adapts to your body shape, while also offering enhanced bounce, temperature-regulation, and a fresh, natural feel.

A fresher sleep, all year round

The Spring King® Wool Luxury Pocket Mattress is finished with a soft, cotton quilted cover, which enhances breathability to create a fresher sleeping environment. An anti-slip base keeps your mattress in place, and the 32cm depth ensures it takes pride of place on any bed frame 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.

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.

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

Medium feel is ideal for couples and a range of sleeping styles
Individually pocketed springs provide tailored support and reduce partner disturbance
Natural wool fibres regulate temperature for year-round comfort
Comfort foam layer adds cushioning without losing supportive feel
32cm deep profile for a truly luxurious sleep surface
