Description

Settle in for quality sleep atop the Silentnight Sleep Right™ Memory 1400 Mirapocket® Mattress. Featuring pressure 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.

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. Allowing you to achieve a more fulfilling slumber.

Cosy feel

A layer of polyester fibres is densely packed, helping to create a layer of firmer comfort. This prevents you from sinking in too deep and losing support throughout the night.

Sturdy design

Designed with your comfort and peace in mind, this mattress features a rod edge border. This places a durable rod across the perimeter of the spring unit for a firmer edge. So you can stretch out without a ‘roll-off’ feel.

Proven perfection

In-house testing at Silentnight includes mapping analysis that 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.

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.

Complete with a 5 Year Guarantee to ensure you get the quality product you deserve.

100-Night Comfort Trial

This mattress comes with a 100-Night Comfort Trial - like all of our mattresses!

The trial lets you test your mattress for up to 100 nights. If it's not quite right for you, you can exchange it for a new one. To be eligible for the Comfort Trial, you'll need to purchase a mattress protector from MattressOnline with your new mattress.

It can take some time to get used to a new mattress, which is why we ask you to sleep on your mattress for 30 nights. If you're not happy with the feel after 30 nights, simply contact our Customer Service Team, and we'll arrange a mattress exchange.

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
