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 and adaptable nature helps them react to your movement and weight, providing support exactly when you need it. Zoned to be firmer in the centre third, this spring unit provides greater support to your shoulders, back and hips. This helps encourage better spinal alignment and reduces aches.

Comforting bliss

Ease into cosy comfort with a layer of Memory foam as it shapes around your body. Lifting weight off your pressure points, it provides blissful pressure relief. Memory foam absorbs movement to limit roll-together and reduce partner disturbance ensuring restful, undisturbed nights of rest.

Adding to the comfort, there are two layers of soft white fibres. These fibers are not only plush but also breathable, increasing airflow and dispelling moisture and heat. They are also exceptionally strong, enhancing durability for longer use.

Scientifically proven

Designed and made in the UK, this mattress has met the highest safety and quality standards. This mattress has undergone pressure mapping analysis. Scientifically proving the Memory foam layer relieves pressure buildup to ease aches.

The zoned Mirapocket® spring unit is tested with movement analysis to show spinal alignment. The results show it helps support the spine better than a standard pocket sprung unit and encourages optimal spinal alignment.

Added comfort

Finished with a microquilted surface that is finely filled with Reflex foam and soft white fibres. This provides a smooth and plush finish to your mattress for cosy comfort. Encasing the mattress is a soft knitted cover that is breathable, helping to promote airflow through the mattress. OKEO-TEX® certified, this cover is free from any harmful substances.

B-Corp certified

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.

Guarantee

Comes complete with a 5 Year Guarantee to protect against any manufacturing faults should they occur during this period.
