Description

The Silentnight Miracoil Pillow Top Mattress is a perfect balance between comfort and support, with a fantastic medium-firm feel.

Full body support

Silentnight's innovative Miracoil spring system absorbs movement, preventing any partner disturbance during the night and whilst providing firm, body-wide support. The springs are zoned to provide targeted support to key points such as the hips, back and joints - just where most of our customers report needing it most.

Plush, sustainable fillings

This mattress also features a comfortable pillow top, filled with Eco Comfort Fibres™. Eco Comfort Fibres™ are soft, highly breathable and sustainable, meaning they are low impact on the environment.

The healthy choice

Hypoallergenic and free from foam and chemical treatments, this mattress is a great choice if you're looking for a naturally healthier sleep, or if you suffer from allergies.

Simply rotate to keep in tip top shape

As this mattress is single-sided, there's no need to flip it over. Simply rotate it top-to-bottom once every three months to ensure even wear across its lifespan.
