What the Sleep Expert thinks...

"This is the mattress I recommend to those looking for a gorgeously soft feel that also provides essential support AND keeps you cool and comfortable. It really does do what it says on the tin!"

Description

Silentnight’s UltraGel™ 1000 Pocket Pillowtop mattress is engineered for those who want an indulgently soft feel and an impressive cooling sensation in one. With a clever gel-infused comfort layer and premium Mirapocket® spring support, it adapts to your every movement while helping you stay cool and pressure-free all night long.

Cooling technology prevents overheating

The UltraGel™ layer provides expert comfort, gently conforming to your body to relieve pressure on joints and muscles while bouncing back with ease as you move. The most impressive part about this technology, however, is that it actively draws heat away from your body thanks to its gel design, preventing overheating and keeping you at the optimal sleeping temperature.

Moves with your body for freedom and support

The plush pillow top of this Silentnight mattress is what makes it luxuriously soft, letting you 'sink-in' blissfully as soon as you climb into bed. However, for essential support, hundreds of Mirapocket® springs respond to your movements, targeting precise pressure relief at your heaviest points to help keep your spine aligned.

Breathable comfort with a plush finish

A mesh border promotes airflow throughout the entire mattress, further encouraging that fresh feel you'll love. Stabilising and protective layers throughout the inside of the mattress enhance durability, ensuring you can enjoy the indulgent comfort of the UltraGel™ 1000 Pocket Pillowtop mattress for as long as possible.

Features

1000 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.

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.

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.
