For the highest standards of quality and safety
Consider the Silentnight British Wool 2400 Pocket Mattress for perfect sleep. Enjoy the natural wonders of British craftsmanship.
Sumptous wool
The British wool fibres are sourced from Cheviot sheep for their unique 3d crimp that offers a soft yet sturdy feel. Delivering a slight bounce that is perfect for that cosy, comforting feel. Wool is naturally temperature regulating to keep you warm in winter and feeling refreshed in summer. Providing perfect seasonal use.
Designed with your reassurance in mind! As part of the British Wools traceable scheme, you can enjoy quality-assured materials sustainably sourced from British farmers.
Incredible support
A count of 1400 Mirapocket® springs are encased in individual pockets for reactive support that is unique to you. As each spring is able to move separately, they work together to create a mattress that adapts perfectly to your shape to aid with spinal alignment.
This spring unit is smartly zoned and firmer in the centre third to deliver optimal personalised support. Pocket springs also reduce 'roll-together' and partner disturbance, making them ideal if you share a bed.
Enhanced by an additional 1000 mini pocket springs for extra comfort on top of this!
Pressure relieving
Enhancing the comfort of the natural wool is the Platinum comfort layer. This material is made to hold the best properties of memory foam without holding onto heat. The layer cuddles your contours as it shapes around them, lifting weight off your body. This improves your blood circulation and eases built up pressure for blissful relief. It is 10x more breathable than traditional memory foam so you can enjoy comforting pressure relief and a fresher, cooler feel.
Satiny smooth
The traditionally tufted surface is topped with a Tencel™ Lyocell cover. Lyocell fabric has a silky texture that is gentle and soft against skin. The silk like attributes of the fabric enable it to wick away moisture, aiding in regulating temperature for an acclimated sleep. The cover works together with the breathable wool fillings to perfectly cater to hot sleepers and hotter climates.
Lasting brilliance
Additional durability is offered by the layer of Coir fibres so that your mattress stays in its best shape for longer. This material comes from coconuts and is robust and elastic to help retain the quality of your sleep. Improving the durability of the mattress further is the traditionally tufted finish. This design secures all layers of the mattress in place to help it retain its shape.
B-Corp certified
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.
5 Year Guarantee
Enjoy undisturbed comfort with added peace of mind as the British Wool range comes complete with a 5 Year Guarantee!
This mattress comes with a 60-Night Comfort Trial - like all of our mattresses!
The trial lets you test your mattress for up to 60 nights. If it's not quite right for you, you can exchange it for a new one.
It can take some time to get used to a new mattress, which is why we ask you to sleep on your mattress for 30 nights. If you're not happy with the feel after 30 nights, simply contact our Customer Service Team, and we'll arrange a mattress exchange.

Very comfortable mattress would definitely buy this again
Verified Purchase
Extremely poor quality, the springs were coming through the surface padding. I have always bought Sleepeezee (we have 2 others at home) so didn't look at other brands but this was a complete let down.

Super, Well made, Great quality, natural wool mattress. Trying to use more natural materials especially against my skin, so this was perfect for me. Also keeps my body temperature at a comfortable level. I now sleep through the night without waking to switch on fan, due to being too hot. And it is a heatwave right now. 10/10

Excellent medium mattress. Very comfortable and ensures a good night's sleep. Very happy with medium firmess and still so cosy!

Good quality and good temperature regulation. However, too firm and already noticing dips in mattress.

Very good quality mattress - it is on the firm side of medium and gave me a little bit of back pain initially, however it has softened nicely after a few weeks and is now very comfy.
