The Silentnight Memory Cool 1000 is a hybrid mattress from Silentnight, the UK's leading bed and mattress manufacturer, made in Great Britain. It's built around 1000 of Silentnight's Mirapocket pocket springs, each working independently, and topped with graphite-infused Memory Cool™ foam engineered to sleep 15% cooler than standard memory foam. The result is a medium-firm mattress that cushions pressure points, keeps you comfortably cool through the night, and minimises partner disturbance thanks to its independently pocketed spring system and Miratex foam edge support.
A hybrid mattress best suited to sleepers who want medium-firm support, effective cooling and minimal partner disturbance.
Medium Firm Feel - 4/6: A supportive feel with added stability. Ideal for people who change sleeping position during the night and need a balance of comfort and support.

1000 Mirapocket Springs
What it is: Silentnight's individual small springs, each housed in its own separate fabric pocket for independent movement.
How it helps you sleep: Spreads your weight evenly across the bed for zonal, targeted support and spinal alignment, while eliminating roll-together so you're less disturbed by a partner moving.
Memory Cool™
What it is: Silentnight's graphite-infused memory foam technology, designed to sleep 15% cooler than traditional memory foam.
How it helps you sleep: Gently adapts to your body's contours for pressure relief at the shoulders and hips, while the graphite particles absorb and disperse body heat for a fresher sleep environment.
Comfort Foam Layer
What it is: A durable foam layer positioned above the spring system.
How it helps you sleep: Adds extra cushioning on top of the springs, giving a soft, sink-in feel as soon as you lie down.
Miratex Foam Edge Support
What it is: Silentnight's high-density foam running around the perimeter of the mattress.
How it helps you sleep: Supports the mattress right to the very edge and absorbs partner movement, giving you more usable sleeping space without roll-off.
Quilted Cover
What it is: A cover where the top and side comfort layers are quilted together for a smooth, contemporary finish.
How it helps you sleep: Keeps fillings secured in place for a smooth, even sleeping surface night after night.
Flag-stitched Handles
What it is: Handles sewn onto both sides of the mattress using a flag-stitch method.
How it helps you sleep: Makes it easy to reposition and rotate the mattress, helping you maintain it properly for lasting comfort.

Vs firmer mattresses: This mattress strikes a more forgiving balance at the shoulders and hips than a firmer option, while still offering enough structure underneath to suit combination and front sleepers. If you tend to change position through the night or want cushioning without losing support, this is likely the better fit. Firmer mattresses suit heavier sleepers or those who prefer a more rigid, unyielding surface.
Vs softer mattresses: This mattress offers more structural support beneath its comfort layers than a softer option, thanks to its independently pocketed spring system. Softer mattresses can feel more immediately plush but may not maintain spinal alignment as consistently over time, particularly for combination sleepers or couples with different body weights.
Vs premium and luxury mattresses: This mattress shares the same core technology - independently pocketed springs and graphite-infused cooling foam - found in higher-priced hybrid mattresses. The difference is typically in the depth of the comfort layers and the range of natural fillings used, rather than any compromise in the quality of the spring system or cooling performance.
The Silentnight Memory Cool 1000 is backed by Silentnight's 5 year manufacturer's guarantee against defects in materials and workmanship. Built in Great Britain using Silentnight's exclusive Mirapocket spring system and Memory Cool™ technology, this is a mattress designed for lasting comfort and support, and the guarantee reflects that confidence.
National Bed Federation (NBF) Approved - Independently verified to meet strict UK standards for quality, safety and responsible manufacturing.
Carbon Neutral Organisation - Silentnight is certified as a Carbon Neutral Organisation, reflecting a genuine commitment to environmental sustainability and a greener future.
Made in Britain - This mattress is manufactured in Silentnight's specialist UK factory.
The Memory Cool 1000 delivers a rare combination for its price point: genuine cooling technology, independently pocketed spring support, and a medium-firm feel that suits most sleeping positions. If you run hot at night, share a bed, or simply want a supportive mattress that keeps its shape night after night, this is one to consider.
