Description

With a medium-firm feel, the Silentnight British Wool 2400 Pocket Mattress is perfect for those who prefer a firmer bed with intense support, as well as gentle cushioning from natural, breathable fibres.

Orthopaedic support thanks to innovative Miracoil® springs

Hundreds of Silentnight's innovative Miracoil® springs form a body-contouring layer of orthopaedic support. Adapting to your movements in the night, these independent springs work like piano keys, adjusting to support your body in key areas. By keeping your hips and shoulders supported, your spine stays perfectly aligned and your posture controlled, encouraging a healthier sleeping position. A layer of mini springs then provides an even more precise level of support, ensuring your entire body receives personalised pressure relief.

Highly breathable for a fresher sleep surface

A natural Coconut Coir layer, made from the husks of tropical coconuts, encourages air circulation and has a natural elastic property that cushions your pressure points. This sustainable material is complemented by the cocooning platinum comfort layer, which acts as an alternative to foam with a more breathable, cooling feel.

Snuggly soft British Cheviot sheep wool

A generous layer of traceable British wool from Cheviot sheep, known for their strong yet soft fleeces, provides sumptuous comfort and a snuggly soft feel, without compromising your support. With temperature-regulating properties, this wool also helps to keep you cool in the summer and warm in the winter, for a cosy sleep no matter the weather. Finished in a cooling, soft-to-the-touch Tencel™ fabric cover, this mattress is the epitome of British luxury.

Features

Mirapocket® Springs

Exclusive to Silentnight, the Mirapocket® spring system offers outstanding support and superior spinal alignment. It maximises sleeping space and reduces "roll-together" for less partner disturbance - making it ideal for couples.

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.

Cocooning Platinum Comfort Layer

An alternative to memory foam, this material cushions your body while encouraging air circulation for a fresher pressure-relieving experience.

Coconut Coir Fibres

From the husks of tropical coconuts, this fibre combines strength and elasticity. These properties help it support your body while also enhancing the durability of your mattress.

29cm Depth

This mattress is approximately 29cm deep.

Natural Tencel™ Fabric Cover

Innovative Tencel™ technology combats bacteria growth and keeps you fresh and cool. Wicking away excess moisture, it also helps to regulate your temperature and prevent overheating.

Orthopaedic Support

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

Air Vents

Vents which allow air to flow in and out of the mattress are mounted on the sides. These vents help to keep the air within fresh and cool.

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.
