Firm Silentnight Mattresses

Super King (6')

This mattress is designed to offer targeted edge-to-edge support for more sleep space and individual comfort. With Silentnight's Mirapocket spring system encasing 1400 individual pocket springs which respond independently to the weight and offer to zone across the mattress, scientifically proven to provide superior spinal alignment and body support. Hand-tufted through the mattress produces a luxury traditional appearance while eco-comfort fibres allow for a more refreshing experience as it's made from 100% recycled plastic bottles which encourage natural airflow for more breathability through the night.

Featuring eco-comfort fibers, this mattress is good for you and good for the environment, as its comfort layer is made from 100% recyclable plastic bottles which offer breathability and enhanced comfort for a more refreshing night's sleep. Tried and tested Miracoil®'s spring system also has enhanced durability providing superior comfort over many years.
