What the Sleep Expert thinks...

"For budget-conscious buyers, Essentials 600 still nails the basics: Mirapockets reduce motion, Eco Comfort fibres breathe, and medium support suits most positions. Single-sided, UK-made, and NBF-approved - it’s an ethical mattress upgrade."

Description

Silentnight is one of the most popular mattress brands in the UK, and their Essentials 600 Mirapocket Mattress is one of their top models. Combining their exclusive Mirapocket design and planet-friendly Eco Comfort Fibres, this medium support mattress provides you with cushioned comfort and plenty of support along the spine, hips, and shoulders for a more restful night’s sleep. At 23.5cm deep, it certainly offers you plenty of mattress for your money!

The 23.5cm-deep Silentnight Essentials 600 Mirapocket Mattress is a single-sided mattress, so there is no need to flip and turn. However, it is recommended that you rotate the mattress from ‘top-to-toe’ every few months to prolong its lifespan and to avoid any dips or bumps from forming. The design of the mattress ensures that any pressure points along the back, hips, and shoulders are eliminated, so that your spine stays in the neutral position no matter how you sleep. The individually pocketed Mirapocket springs minimise movement transference so even if you like to wriggle about at night, you won’t disturb your partner.

Mirapocket design with 600 pockets in the King Size model

Silentnight’s exclusive Mirapocket spring system offers exceptional support and keeps your spine in a neutral position whether you sleep on your front, side, or back. Because the mattress is supported all the way to the edge you have more room to stretch out in complete comfort, with no roll-together.

Eco Comfort Fibre that doesn’t cost the earth

The mattress is plumped up with Eco Comfort fibres that are made from sustainable sources and are 100% recyclable, making this mattress an ethical choice.

NBF-approved product and made in the UK

Silentnight is one of the most respected mattress manufacturers in the country, and have been helping the British public sleep well for over 60 years. This premium quality Silentnight Essentials 600 Mirapocket Mattress is approved by the National Bed Federation, and also conforms to the BS7177: 2008 standard for domestic use. It also comes with Silentnight’s 5-year guarantee to give you total peace of mind.

Features

600 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.

23.5cm Depth

This mattress is approximately 23.5cm deep.

Quilted Cover

The quilted cover is created by stitching the mattress cover and the fillings together, creating a patterned comfort quilt layer.

No Need To Turn

A single-sided mattress which does not need to be turned/flipped. One-sided mattresses should, however, be rotated head to toe regularly.

Vacuum Packed & Rolled

Rolled mattresses have the advantage of being easy to transport, especially to upstairs bedrooms. When unrolled, they expand fully over time, usually being comfortable enough to sleep on after 48 hours.

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.

Pressure Relieving

This type of mattress gives maximum pressure relief, allowing your body weight to spread across it evenly. This ultimately means less tossing and turning throughout the night and a more relaxing and restful sleep.

Hypoallergenic

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

Made in the UK

This item has been manufactured in the UK.

Fire Resistant - Low Hazard
