Description

Settle in for quality sleep atop the Silentnight Memory 1400 Mirapocket Mattress. Relieving Memory foam with a core of zoned support.

Pocketed support

A core of Silentnight's Mirapocket® springs offer incredible zoned support. This enhances your rest by targeting key areas of the spine, helping to improve sleep posture. Making it easier to sleep comfortably and deeply by providing superior support. Isolated into individual fabric pockets, allowing them to move separately. These springs also minimise motion transfer and feelings of 'roll-together'. Helping you to remain undisturbed throughout the night.

Reliable feel

With an extra firm finish, this mattress offers an enhanced sense of sturdy support. So that you can stretch out feeling completely supported. Enjoy a sleep surface with a truly solid appeal.

Soothing comfort

The Memory foam comfort layer responds and adapts to the contours of your body. Creating a cradled feel to enhance the comfort of your rest. Helping to alleviate pressure spots, easing aches as you rest. Helping you to achieve a more fulfilling slumber.

Protected feel

A protective layer of polyester fibres beneath the spring unit disperses their pressure. This improves the mattress' longevity, helping your mattress to stay in its best shape. So that you can enjoy that truly amazing mattress feel for longer.

Proven perfection

In-house testing at Silentnight has supported their effectiveness in creating a better mattress feel. Pressure mapping analysis has proven that the Memory foam disperses pressure. Working with experts in movement analysis found an improvement in lower spine support when compared to standard sprung mattresses. Ensuring that Silentnight makes no hollow promises.

Sumptuous surface

Topped off with a cosy quilted cover to create a truly wonderful sleep surface. A brilliant place to lay down after a bustling day to get the rest you need. OKEO-TEX certified material to ensure that you don't come into any harmful substances. Helping to protect you from irritation that may otherwise disrupt your sleep.

Assured quality

As one of the first B-Corp certified sleep brands, Silentnight have proven why they are the UK’s most trusted name in sleep. Their commitment to quality and environmentally responsible practices ensures a better night’s rest and a brighter future for you.

Hi David I am sorry you are not finding your mattress comfortable - we appreciate the feedback. I can see that you have contacted our Customer Service team regarding exchanging your mattress. Unfortunately, we only offer one Comfort Trial per order so would not be able to exchange the mattress again. Kind regards Charlie
