A Which? Best Buy Hybrid Mattress

This outstanding hybrid 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.

Cooling memory foam comfort

When you snuggle into the Discovery, you'll feel the cooling freshness of graphite-infused memory foam. This 7.5cm thick layer makes it one of the deepest memory foam mattresses around!

Breathable and fresh

No more overheating! The clever graphite-memory layer includes a built-in airflow system to improve ventilation through your mattress.

Healthier sleep

The intelligently-designed memory foam layer whisks away moisture and regulates your temperature. It's hypoallergenic, too, so you'll enjoy a healthier, more comfortable sleep.

Perfect body support

The Discovery features 1500 pocket springs which react to your unique body shape. They provide completely personalised support, exactly where you need it.

Not too soft, not too firm

Looking for that just-right feel? You've found it! We rate the Discovery medium. That means it's the perfect balance of comfort and support.

Extra sleeping space

This is a mattress that's perfect if you or your partner are fidgety sleepers. Not only do the pocket springs prevent movement transfer - the mattress sides are reinforced with sturdy foam, too. This helps prevent roll-off and gives you more sleeping space.

No fuss, easy-care

It's easier than ever to keep your mattress clean and fresh. The Discovery is wrapped in a super-soft knitted cover that you can easily spot-clean when you need to.

Since it's single-sided, you'll never need to turn it over. Simply rotate every 3 months using the built-in turning handles to keep it in great condition.

Better for you - and the planet

Your new mattress will arrive rolled-up for easy moving and handling. Simply pop the mattress on your bed, unwrap and leave it to expand. It'll be ready to sleep on in 3-4 hours.

Since we can fit more roll-up mattresses into every delivery van, it helps lower our carbon emissions. So it's better for the environment too.

Discover a new world of comfort

Discover the cooling freshness of the Horizon Discovery today - and enjoy out-of-this world comfort as soon as tomorrow!
