What the Sleep Expert thinks...

"If you sleep hot (or sneeze often) start here. 1,200 zoned Mirapockets lift where needed, while Purotex probiotics and Eco Comfort fibres tackle allergens and heat. Double-sided for longevity. Just flip and rotate, and it will reward you for years."

Description

If there’s one name you know you can trust when it comes to buying a mattress, it’s Silentnight. The Silentnight 1200 Mirapocket Eco Comfort Mattress really does live up to its name too – this beautifully constructed mattress is made up of 1200 individual mirapocket springs that allow maximum airflow and comfort without putting pressure on your hips or lower back. Its zoned areas ensure that each part of your body gets the support it needs, to guarantee a restful night’s sleep.

Silentnight has over 60 years’ experience in crafting beautifully-made mattresses that deliver a restful night’s sleep. The Silentnight 1200 Mirapocket Eco Comfort Mattress uses their Mirapocket zoned spring system, which provides firmer support for your lower back and hips. Softer zones sculpt to the upper and lower body, so your spine stays aligned and pressure points are avoided. A good night’s sleep is absolutely essential for good mental and physical health, so we recommend that you change your mattress every 5-8 years to achieve the maximum benefits. Thanks to the double-sided construction, the mattress can be ‘turned and flipped’, which extends its life.

Purotex keeps mites and dust at bay

The mattress from Silentnight is treated with Purotex, a revolutionary technology that uses tiny capsules of 100% natural probiotics to combat mites and allergens. The mattress also has layers of Eco Comfort fibre, which are soft white fibres that are made from recycled plastics. That makes the 1200 Mirapocket Eco Comfort one of the greenest mattresses around, and perfect for asthmatics and those suffering from allergies.

Firm support with a cloud-soft cover

The 1200 Eco Comfort gives you all the support you need with a medium firm feel. But if you’re looking for that ‘snuggle factor’ then you’re in luck - you’ll be sleeping on top of a cloud-soft cover made from breathable material that stays cool and comfortable all night long.

A 5-year guarantee gives you nearly 2,000 restful nights!

Silentnight mattresses come with a 5-year guarantee, so you have total peace of mind. The mattress is made in the UK too, so you know you’re supporting local UK businesses when you buy the Silentnight 1200 Mirapocket Eco Comfort Mattress!

1200 Mirapocket® Springs

Exclusive to Silentnight, the Mirapocket® spring system offers outstanding support and superior spinal alignment. It maximises sleeping space and reduces "roll-together" for less partner disturbance - making it ideal for couples.

Eco Comfort Fibres™

Breathable and sustainable fibres that are 100% recyclable give you a fresh and purifying sleep from eco-friendly materials that won’t cost the planet or your pocket. Eco Comfort Fibres™ have been scientifically proven to keep you cooler while you sleep.

Knitted Cover

Reinforced Edges

The mattress has reinforced edges, so that the full sleep surface can be used. This means more sleeping space - which is usually lost in conventional, less edge-stable mattresses.

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.

Turnable

The mattress has fillings on both sides. Double-sided mattresses need to be turned regularly to keep them in good condition.

Hand Tufted

Tufts help to secure the luxury fillings in place, helping the mattress retain it's fullness and plumpness over time.
