Features

1000 Pocket Springs

Pocket springs are springs mounted in their own separate fabric pockets, meaning they work completely independently of one another and can provide your body with better pressure relieving support.

Silk

Soft in texture and light in weight, luxurious silk creates the ultimate top comfort layer to any mattress.

Cashmere

A rare filling which is softer and finer than wool. Cashmere is only used in quality products.

Authentic Traceable British Wool

100% traceable from farm to shop, this wool is from British Cheviot sheep, known for their strong yet soft fleece. Providing a natural bounce, this wool also helps to regulate your temperature.

Highly breathable and soft to the touch, this cover finishes the mattress with a truly luxurious feel.

Orthopaedic Support

Air Vents

Vents which allow air to flow in and out of the mattress are mounted on the sides. These vents help to keep the air within fresh and cool.

No Roll Together

Individual personal sleeping zones mean that you won't be disturbed if your partner rolls or moves, as you won't feel their motion. There's also no tendency to roll towards the middle of the mattress.

Turning Handles

Flag-stitched handles are attached to the sides of the mattress to assist in turning or rotating.

Hypoallergenic

Being hypoallergenic, this is the perfect item for allergy sufferers - or anyone looking for a healthy night's sleep.

Poor experience misleading prod…

Poor experience misleading product and slow customer servicei bought a mattress recently and straight away noticed a bump in it. I sent photos as requested, and was told it would be passed to the supplier, but its now been over a week and I havent heard anything back and im using the new mattress as I have no other options.Also, I noticed the depth on the website said 28cm, but the plastic wrap said 23.5cm, which is a big difference. I sent a photo showing the measurement with a tape measure. The lady I spoke to on the phone said I measured it incorrectly and sent me new instructions, which I followed still no response after that.She also told me they couldnt do anything unless I sent a photo of the label on the wrap but id already thrown it away because their ai assistant only asked for a photo of the mattress itself. When I explained that, she said thats only ai, which really confused me. Am I supposed to follow the ai or not?overall, I feel misled by the product listing, and the customer service has been disappointing. Ive spent time chasing this with no real progress or support.The mattress itself feels ok after a week sleeping on it although I wouldnt say its firm. Also, if you sleep on it with someone, you can literally feel every movement which its not something I would expect from a pocket spring mattress.
