Description

The Silentnight UltraGel 1000 Mirapocket Mattress provides pressure-relieving comfort and personalised full body support.

Zoned support

The core of this mattress is formed from 1000 Mirapocket® springs. These springs are encased in separate fabric pockets to allow them to move independently. Promoting full body support, personalised to you. Mirapocket® spring units are zoned in the centre third to provide greater support to your back and hips. This encourages blissful spinal alignment and helps to ease aches.

UltraGel foam

Silentnight’s exclusive UltraGel™ foam moulds around your unique shape and adapts to your movements. This helps it lift weight off your body and is scientifically proven to deliver rejuvenating pressure relief. Ultragel™ foam features a bounce-back feel which makes it easier to move around without sinking in too deep. Featuring an open cell structure, this foam is highly breathable, encouraging a fresher feel.

Comfort fibres

Adding to the comfort of this mattress are layers of soft white fibres. These fibres are densely packed to create durable and comforting layers. The fibres are highly breathable, increasing air flow throughout the mattress and working well with the UltraGel™ foam to deliver a fresher feel.

Breathable border

This mattress design includes a small breathable mesh border. This fabric increases the airflow throughout the mattress. Helping to dispel heat and moisture, providing a fresher feel and reducing a build up of mould and mildew.

Zero ‘roll-off’ feel

The border of this mattress features a rod edge border. This is built from sturdy rods that are placed at the top and bottom of the spring unit. These rods enhance the stability and durability of the mattress edge. This means you can enjoy a maximised sleep space with a minimised ‘roll-off’ feel.

Medium to firm

The zoned spring unit provides tailored support and topped with plush comfort layers this mattress provides a medium firm feel.
