What the Sleep Expert thinks...

"This mattress provides serious support with a firm feel. It's ideal if you're looking to prevent backache, and the cooling sensation helps to ease joint aches and pains."

Description

Silentnight’s UltraGel™ 1400 Pocket Mattress offers impressive orthopaedic support plus cooling comfort for a truly refreshing, rejuvenating night's sleep. Combining the clever cooling feel of UltraGel™ with up to 1400 Mirapocket® springs, this innovative mattress adapts to your movements for maximum support and comfort.

Responsive orthopaedic support as you move

A layer of up to 1400 Mirapocket® springs (in the king size) works independently to support your body from head to toe, responding to your movements for consistent, zoned support. These individually encased springs enhance spinal alignment by focusing support to your hips and shoulders, keeping you in a healthier sleeping posture and reducing the chances of aches and pains. Reinforced edges and a tufted surface help to maintain your mattress's structure, offering long-lasting firmness and edge-to-edge support so you can stretch out comfortably night after night.

Bounce-back comfort with breathable UltraGel™

Silentnight’s innovative UltraGel™ comfort layer offers the cushioning feel of foam with added breathability and a unique cooling sensation. Gel-infused, this comfort layer gently moulds to your body while drawing heat away, keeping you at an ideal sleeping temperature. Perfect for hot sleepers!

Practical design details for enhanced durability

Durable and stabilising foam layers are added between the comfort layers of the mattress, protecting from the inside out and allowing you to enjoy the Silentnight UltraGel 1400 Pocket Mattress for as long as possible. Finished with a plush tufted sleep surface, this mattress adds a touch of luxury to your bedroom while supporting a proper night's sleep for anyone who tries it.

Features

1400 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.

UltraGel™ Memory Foam

This advanced comfort layer is 5x more breathable than standard memory foam, offering soothing pressure relief, gentle bounce-back, and a cooler, more undisturbed night’s sleep.

29cm Depth

This mattress is approximately 29cm deep.

Quilted Sleep Surface

Modern quilted soft-knit fabric for a smooth and comfortable sleep surface.

Orthopaedic Support

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

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 Tufted

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

Breathable Mesh Border

Soft and hypoallergenic, this border allows for maximum air circulation thanks to an innovative mesh design.

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.
