For firm, reactive support that works with your body, the Jay-Be Flex Ultra-Firm 1200 Pocket Mattress features deep ultra-firm pocket springs and generous layers of e-Fibres™ for foam-free comfort.

Reactive, orthopaedic pocket springs

Using advanced pocket spring technology to bring you impressively firm support, this mattress features up to 1200 ultra-firm springs. These independently pocketed springs contour to your body shape, gently reacting to your movements to provide targeted, tailored support. With a firm feel, these springs ensure orthopaedic levels of comfort at every point of contact, and align your hips and shoulders to prevent your spine from uncomforably over-arching. This level of tension is also ideal for those of a heavier build, as it prevents you from dipping into the mattress surface.

Pressure-relieving, foam-free comfort layers 

For foam-free comfort that's as breathable as it is cushioning, generous layers of e-Fibre™ provide a range of benefits. High Density e-Fibre™ provides a foundation of solid comfort and insulation for the colder months, while breathable Rebound e-Fibre™ cushions every pressure point with moisture-wicking, refreshing comfort. Firm e-Fibre™ ensures this mattress maintains its firmness level, and finally, Advance e-Fibre™ adds blissful tension relief for a weightless sensation. These clever fibre layers let you enjoy full-body, complete comfort without the need for foam, keeping you fresh all night long.

Sustainable and durable for nights of comfort

Naturally hypoallergenic and made using over 70% recycled materials, the Jay-Be Flex Ultra-Firm 1200 Pocket Mattress is as good for the planet as it is for your body. You can enjoy night after night of truly refreshing and rejuvenating rest thanks to enhanced air circulation, courtesy of a 3D mesh ventilated fabric border, and a durable construction backed by a 10-year guarantee. Finished in a deep quilted knitted sleep surface, this firm Jay-Be mattress is sure to help you start getting the rest you deserve.
