Description

The Silentnight UltraGel 1200 Mirapocket Pillow Top Mattress combines two Silentnight exclusive designs for personalised support and rejuvenating pressure relief.

Mirapocket support

Holding a core of 1200 Mirapocket® springs for ultimate full body support. Mirapocket® springs are designed to sit within their own fabric pockets to allow them to move independently. This means they respond to your individual movements and weight, delivering responsive support. Mirapocket® springs include a zoned design that is firmer in the centre third of the unit. This provides greater support to the areas that need it most like your lower back and hips. So you can lay back and relax night after night with full body support on your side.

Pressure-reliving foam

This mattress is complete with a 3cm layer of UltraGel™ foam. Designed exclusively by Silentnight, UltraGel™ offers a unique structure with a fresher feel. It features an open cell structure that allows air flow freely and disperse heat.

This special foam is made to shape around your body to deliver a comforting embrace with strong bounce-back abilities. Making it easy to move around without losing comfort or experiencing partner disturbance. UltraGel™ foam is scientifically proven to evenly distribute your weight to lift pressure off your body for the dreamiest rest.

Soft fibres

Soft white fibres add an element of extra comfort with their snug feel. Highly breathable, these fibres help to enhance the fresh feel of the mattress. They are strong and durable to encourage greater longevity and keep the mattress shape for longer.

Mesh border

Adding to the breathability of the mattress is the mesh border. This fabric design offers greater room for airflow throughout the mattress. This can encourage heat and moisture to dispel, for a fresher feel.

Durable edge

Featuring a rod edge border for enhanced perimeter stability. This design is created with durable rods placed across the top and bottom of the spring unit. This adds a firmer feel to the edge of the mattress so you can sleep right up to it without a ‘roll-off’ feel. You can also enjoy having a maximised sleep space, perfect when sharing the bed!

Silentnight quality

Experts in the mattress industry with over 70 years of experience, Silentnight offers comfort and support you can rely on. This mattress has been crafted in the UK which means it adheres to the highest safety and quality standards.

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.
