Description

The SleepSoul Space 4000 Pocket Orthopaedic Gel Mattress takes you to a whole new world of comfort with hybrid features and soothing pressure relief care.

Pocketful of sunshine

The interior of this mattress holds 4000 springs, this spring count is based on a kingsize mattress. This consists of 2000 full size pocket springs and 2000 mini pocket springs. All pocket springs within this mattress are fashioned from durable steel to provide long lasting care. Once shaped with sufficient bounce, the springs find home in their own fabric pockets before being secured together. The spring unit is then fully formed and ready to supply personalised support. Due to their construction, these springs are highly reactive. They can adapt to motion to ensure support is given in the areas that require it most. This also helps to promote minimal partner disturbance throughout the night.

Ideal firmness

If you suffer from back discomfort and pain then this mattress is the perfect choice for you. Rated firm, meeting your body with just the right amount of support. Unlike soft mattresses, you will not sink into the surface which can make it harder to move in the night and can add stress to your back. The firmer comfort surface keeps your spine in soothing alignment to reduce pains and deliver orthopaedic support.

Foam perfection

The first layer of foam within this mattress adds a great comfort feel to this firm mattress. The layer helps to equally distribute your weight. Delivering a balanced surface so you are correctly supported throughout the night. Foam is renowned for its durability and ability to lift pressure off your joints and muscles. So you can truly unwind and wake feeling rejuvenated.

Sat beneath the soft foam is a layer of Cool Gel foam. This layer is cooling, fresh and comfortable. Unlike traditional Memory foam, it allows greater airflow, reducing heat and moisture build up. Creating a cool touch surface that is perfect for hot summer nights.

Comforting cover

Across the exterior you will feel the cosy touch of the tencel knitted cover. Soft to touch, this cover is the perfect surface to rest against. Tencel fabric wicks away moisture to keep your mattress dry and cool. It also holds antibacterial properties for a healthier sleep, free from irritation.

Easy care

This mattress is single-sided which means taking care of it is much simpler. Use the turning handles provided to rotate top to toe. It is recommended to do this every 3-6 months to keep your mattress feeling fresh. Following a care routine limits the chance of stains, odours and dips building up on your mattress surface. The conveniently included handles also make moving the mattress when rearranging or moving a breeze!

Quality design

Holding over 20 years of experience, it is clear to see that SleepSoul are experts in the mattress world. Creating innovative, cosy designs with high quality materials to ensure the best nights sleep for their customers. Finished with a 10 Year Warranty for further reassurance and protection against any manufacturing faults. To activate this warranty, make sure to register the product information on the manufacturer's website within 30 days.
