The obvious choice for those who need firm, consistent support, but don't love the idea of foam, the Jay-Be Flex Ultra-Firm Mattress provides orthopaedic comfort and complete breathability.

Firm orthopaedic comfort

At its core lies a strong, supportive sprung system engineered to promote healthy spinal alignment. The open-coil, ultra-firm sprung core evenly distributes your weight over the surface of the mattress, giving you a weightless feeling and applying tension relief at every point of contact. The firm feel of this mattress is perfect for offering extra spinal support and is also ideal for those of a heavier build, keeping you on the surface of the mattress.

Supportive e-Fibre™ comfort layers

Layers of Firm e-Fibre™ and Rebound e-Fibre™ create a stable yet comfortable surface that gently cushions your body without a foam-like sinking feeling. Instead, these clever layers provide just the right amount of pressure relief to keep you wonderfully comforted in all the right places. Additional layers of High Density e-Fibre™ and Advance e-Fibre™ provide even more full-body cushioning, all the while maintaining the firm feel of the mattress, and encourage air circulation for a truly refreshing sleeping environment.

Foam-free and breathable design

Made without foam, the Jay-Be Flex Ultra-Firm Mattress promotes natural airflow and temperature regulation to help you enjoy a fresher, cleaner night’s sleep. It's also hypoallergenic, making it ideal for allergy sufferers, and is made from over 70% recycled materials, providing complete peace of mind. Finished in a deep quilted knitted sleep surface, this sustainable, impressively comforting mattress is sure to make getting a proper night's rest that much easier.
