Description

Enjoy cosy comfort with the Silentnight Memory 800 Mirapocket® Mattress. Designed to deliver pressure relief for a blissful rest.

Personalised support

A core of 800 Mirapocket® springs offers support tailored to your needs. These springs are placed in individual fabric pockets that respond independently. The responsive nature helps them react to your movement and weight, providing support where you need it.

Zoned to be firmer in the centre third, this spring unit provides support to your shoulders, back and hips. This helps encourage better spinal alignment and reduces aches.

Comforting bliss

Ease into comfort with a layer of Memory foam as it shapes around your body. Lifting weight off your pressure points, it provides blissful pressure relief.

Adding to the medium to firm comfort are two layers of soft white fibres. These fibers are plush and breathable, increasing airflow and dispelling moisture and heat. They are also durable for a longer performance.

Easy care

The single-sided design means you don’t have to fret about flipping the mattress. Simply rotate top to toe seasonally to encourage even wear.

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.
