What the Sleep Expert thinks...

"Cotton Comfort is a mattress I recommend for approachable, everyday medium support. The six-turn springs and lofty cotton with Solotex™ fibres naturally regulate temperature, and the individual springs mean you won’t be disturbed by your partner’s movements."

Description

Exclusive to MattressNextDay, and from the creators of the most comfortable beds in the World, the Hypnos Cotton Comfort Mattress is nothing short of pure luxury, with traditional hand tufting as a sign of dedicated craftsmanship.

Specially engineered support technology

With Hypnos' bespoke, innovative ReActive™ 6-Turn Pocket Springs, the Cotton Comfort Mattress is highly supportive. These individually pocketed springs feature more turns per coil, which helps them react faster and more effectively to your movements throughout the night. Detecting your pressure relief needs, these springs ensure maximum support to your pressure points, especially your back, shoulders and hips.

A medium feel, this mattress is perfect for all types of sleepers. If you're a side sleeper, this mattress perfectly allows your hips and shoulders to 'dip' into the surface just enough to keep your spine aligned.

Cushioning comfort to your entire body

Comfort layers of soft cotton and Hypnos' special eOlus™ fibres ensure total body cushioning. Cotton naturally wicks away moisture and helps to keep you at the optimal sleeping temperature, while eOlus™ encourages breathability and air circulation.

Not only does the Cotton Comfort Mattress provide expert support and comfort, but it also features no roll together technology, offering you and your partner separate sleeping zones so you don't end up squashed together in the middle of the bed. Completely hypoallergenic, this mattress is also ideal for allergy sufferers, or anyone looking for a fresher night's sleep - a soft damask cover further enhances this freshness.

ReActive™ 6-Turn Pocket Springs

Comprising of 6 turns per spring The Hypnos ReActive™ 6-Turn Pocket Spring System is engineered to provide total spinal and body support. Each spring is designed to independently sense the exact comfort and support requirements of you and your partner, seamlessly and smoothly spreading vertical downward pressure.

Cotton

This mattress filling helps to regulate body temperature. It also provides additional support and natural comfort.

eOlus™ Fibres

eOlus™ fibres are designed to offer resilient body support whilst allowing air and moisture to pass through the material easily. The fibres create a breathable layer that, unlike foam, doesn’t retain heat or sweat, while offering a soft foam-like feel for optimum comfort. No harsh chemicals are used in the manufacturing process which not only means there are no ‘end-of-life’ disposal issues, but the fillings are also 100% recyclable.

Turning Handles

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