    Discover a new world of blissful sleep with the Horizon Discovery 1500 Pocket Memory Mattress!

    This outstanding mattress, in the double size, was reviewed as a Which? Best Buy in October 2020. Which? commented on the Horizon's fantastic durability and overall body support.

    It's clear why this super-comfy mattress is a Which? Best Buy. It features 1500 pocket springs for completely personalised support, exactly where you need it. Reacting independently to your unique shape, pocket springs also help absorb motion and reduce any partner disturbance.

    Nestled on top of the pocket springs, the Discovery features impressively deep layers of foam comfort. Firstly, you'll feel the sumptuously deep 7.5cm layer of high-density memory foam and the cooling freshness of 4G open-cell memory foam. Combined, these beautifully-crafted support layers will envelop you in total comfort and provide soothing pressure relief.

    Intelligently designed to whisk heat away and more breathable than standard memory foam, 4G actually improves airflow by 95%! This means you'll enjoy a fresher sleep - with no overheating.

    Next, you'll feel the breathable comfort of Revo™ foam and the sturdy support from the high-density foam base layer. Together, they'll give you great support, maximum airflow and a cooler sleep.

    This is a mattress that's perfect if you or your partner are fidgety sleepers! The mattress sides are reinforced with sturdy foam to prevent roll-off and more sleeping space.

    Sleep peacefully, knowing your mattress is entirely hypoallergenic. It's easier than ever to keep your mattress clean and fresh, too. The Discovery is finished in a super-soft knitted cover that you can zip it off and sponge-clean or dry-clean it when required.

    Your new mattress will arrive rolled-up for easy moving and handling. Since we can fit more into our deliveries, it's better for the environment too! Simply pop the mattress on your bed, unwrap and leave it to expand. It'll be ready to sleep on in a few hours!

    You'll never need to flip your mattress over, as it's single-sided. Simply rotate it once a month using the built-in turning handles to keep it in the great condition you expect.

    For your peace of mind, the Discovery is covered by a generous 10 Year Guarantee. Please note: the cover is guaranteed for one year. Be an early adopter of this space-age mattress and experience a better night's sleep as soon as tomorrow!
