What the Sleep Expert thinks...

"This is a brilliant mattress for couples, as the medium feel suits any sleeping position. It's also incredibly cooling, which is essential for a deeper, longer night's sleep."

Description

Silentnight’s UltraGel™ 1200 Pocket Pillowtop Mattress is designed to offer you essential support no matter what position you sleep in, plus cooling comfort that regulates your temperature.

Zoned support with a medium feel

At the heart of this 28cm-deep mattress are up to 1200 Mirapocket® springs (in the king size), each working independently to respond to your individual movements. This zoned pocket spring system supports your spine, hips, and shoulders, promoting healthy spinal alignment and helping to reduce aches and pains. Whether you sleep solo or share your bed, the medium feel provides impressive support for a range of sleeping styles.

Breathable comfort that moves with you

The UltraGel comfort layer is Silentnight’s most breathable yet — up to 5x more breathable than standard memory foam — offering responsive cushioning and cooling airflow. It actively draws heat away from your body, keeping you at the perfect sleeping temperature and preventing overheating.

Delicate softness that doesn't compromise support

The plush pillowtop layer offers a final touch of luxurious softness and features a breathable mesh border to encourage air circulation for an even fresher, cooler feel night after night. Innovative stabilising layers throughout the mattress enhance its durability, ensuring you can enjoy the Silentnight UltraGel™ 1200 Pocket Pillowtop Mattress for as long as possible.

Features

1200 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.

28cm Depth

This mattress is approximately 28cm deep.

Quilted Sleep Surface

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

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.

Pillow Top

Pillow top mattresses have the benefit of an additional pillow layer of plush fillings on the top of the mattress, which provides extra luxurious comfort.

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.

Breathable Mesh Border

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