Since 1881, Sealy has been at the cutting edge of mattress development. Today, they are one of the world’s most respected brands, producing premium quality products like the Sark mattress, a medium-firm option that’s ideal for those who prefer a firmer feel or suffer from back pain. With a thousand individually pocketed springs working in harmony to respond to every move you make, you’re assured of a bespoke level of cushioning and support for a more restful and tranquil night’s sleep. Innovative technology keeps you cooler, more comfortable, and more relaxed, so there’s less wriggling and more snuggling!
Although they each form part of a complex and carefully designed matrix, the 1000 springs in the Sark mattress sit in their own individual pockets, so they can also work independently of their neighbours. That allows each spring to respond to every micro-movement you make, continually adjusting and correcting to accommodate your body and provide it with flawless support. The additional layers surrounding this core spring matrix provide extra padding and cushioning.
As well as a complex spring core, the Sark mattress from Sealy also incorporates some clever modern fibres to minimise moisture and eliminate allergens, creating a healthier environment. The Sark uses a combination of Purotex and silky smooth, soft Tencel fibres and Adaptive technology to keep you cooler and fresher. Purotex is endorsed by Allergy UK and is ideal for those who suffer from dust-triggered asthma or rhinitis.
The use of Geltex as a key component of the Sark mattress helps to distribute your weight more evenly across the mattress, eliminating pressure points on those key back, shoulder and hip locations that can lead to more serious back pain. Geltex is also highly breathable and regulates your temperature through the night so you never get too hot or too cold.
The Sark looks as good as it feels, with a soft quilted surface and a depth of 30cm, so you get more mattress for your money. It’s made in the UK and comes with a 5-year guarantee for your peace of mind. This is a single-sided mattress so there’s no need to flip or turn it, but we do suggest that to avoid lumps or dips from forming the mattress is rotated from head-to-toe every six months.
Pocket springs are springs mounted in their own seperate fabric pockets, meaning they work completely independently of one another and can provide your body with better pressure relieving support.
Geltex is a gel-infused foam which increases your comfort and body support. Geltex delivers triple benefits to offer the perfect sleep solution: incredible body support, ideal pressure relief and unrivalled breathability.
Soft white fibre fillings which are made from 100% polyester. This type of mattress filling offers great recovery and is very durable, which means long-lasting comfort.
This mattress is approximately 30cm deep.
Good for people who change sleeping position.
The quilted cover is created by stitching the mattress cover and the fillings together, creating a patterned comfort quilt layer.
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.
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.
A single-sided mattress which does not need to be turned/flipped. One-sided mattresses should, however, be rotated head to toe regularly.
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.
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.
Flag-stitched handles are attached to the sides of the mattress to assist in turning or rotating.
Being hypoallergenic, this is the perfect item for allergy sufferers - or anyone looking for a healthy night's sleep.
This mattress contains 1,000 individually pocketed springs (in a King Size).
