Features you'll love

Soft knitted top cover is breathable and fresh, providing a cooler, more pleasant sleeping environment

Handmade in the UK by a business with a heritage of over 140 years

Vacuum packed and rolled for easy delivery and simple positioning

SuperFlex support foam provides exceptional comfort and support

Extra-firm rating of 6 for a flawless night’s sleep

Single sided so no need to flip and turn regularly


Designed to provide you with extra-firm support with a rating of 6 but with no compromise on comfort, the Horizon Reflex SuperFlex foam mattress is a revelation for back sufferers everywhere. The orthopaedic rating gives you all the support your body needs, but minimises pressure points and moulds to the shape of your body, giving you a more restful night’s sleep with less tossing and turning.

Vacuum packed and rolled for easier delivery

Mattresses are notoriously cumbersome, and an absolute nightmare to get upstairs or along narrow hallways! The Horizon Reflex mattress gets rid of all this by arriving vacuum-packed and rolled for easy transport. Simply take off the vacuum packaging and allow the mattress to return to its original form over 48 hours. The lighter construction makes it simpler to move once it’s restored to its usual shape too.

No flip and turn for easy care

Traditional mattresses need to be flipped and turned regularly to extend their lifespan. Because the SuperFlex foam retains its form so well, you don’t need to do this with the Horizon Reflex mattress, although we do recommend you rotate it ‘head-to-toe’ regularly to extend its lifespan. To give you total peace of mind, your mattress comes with a 5-year guarantee, so you know you can trust it to deliver nearly 2000 restful nights’ sleep!

Made in the UK

Relyon have a history stretching all the way back to 1876, making them one of the oldest bed and mattress manufactures in the UK. They’ve embraced new technology and new materials too, which is why the Bee Rested mattress uses the unique SuperFlex foam in its construction for a much firmer yet responsive surface.

Made in the UK image

The soft knitted top cover allows the mattress to breathe, keeping you cooler and fresher. The mattress is approved by the National Bed Federation, meaning it’s a product that’s been tested thoroughly and has passed the NBF’s rigorous standards. The mattress is 15cm deep.


Reflex Foam

Used together with springs, or as the support layer in all-foam mattresses, Relfex Foam is versatile and comfortably supportive.

15cm Deep

This mattress is approximately 15cm deep.

Extra Firm Support

The firmest level of support. Also known as orthopaedic.

Knitted Cover

This luxurious soft knitted cover is breathable, which helps to keep the sleeper at an even temperature all night long.

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.

Rolled mattresses have the advantage of being easy to transport, especially to upstairs bedrooms. When unrolled, they expand fully and are usually ready to sleep on within 48 hours.
