Select Size Size Guide


MattressNextDay is pleased to introduce the revolutionary Coolflex Supa Ortho Coolmax reflex foam mattress, providing a good level of comfort and firm support. At 20cm deep, it is a very durable mattress which offers an extra-firm orthopaedic tension while still being an exceptionally comfortable coolmax mattress.

The Supa Ortho Mattress is hypoallergenic and antibacterial, which creates a perfect sleep environment for sufferers of allergies and asthma. This coolmax mattress comes complete with a 5-year warranty.


Reflex Foam

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

20cm Depth

This mattress is approximately 20cm deep.

Extra Firm Support

The firmest level of support. Also known as orthopaedic.

Removable & Washable Cover

To aid with hygiene, this product has a zipped cover that can be removed for washing.

Coolmax Cover

The Coolmax cover helps to remove moisture from the sleeper, giving a cooling effect. This also keeps the mattress dry, fresh and hygienic.

Orthopaedic Support

Designed to offer a firmer sleep surface, providing targeted support for your back and joints.

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.

Vacuum Packed & Rolled

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.

No Roll Together

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.


Being hypoallergenic, this is the perfect item for allergy sufferers - or anyone looking for a healthy night's sleep.

NBF Approved Product

Peace of mind and reassurance - the manufacturer of this item is an approved member of the National Bed Federation's Code of Practice.

Made in the UK

This item has been manufactured in the UK.

Fire Resistant - Low Hazard

This product conforms to the BS7177: 2008 standard for domestic use (low hazard) - ideal for use at home.

Warranty & Guarantee

Kayflex 5 Year Warranty

A 5 year warranty which covers you in the unlikely event that your mattress has a manufacturing fault.
