    Jay-Be® Flex Ultra-Firm 1200 Pocket Sprung Mattress, white/black, JAY-BE

    The firm choice for adaptable firm support. If you’re looking for a firmer feel when you sleep, the Jay-Be Flex 1200 Pocket Sprung Ultra-Firm is engineered to deliver exactly that. Inspired by orthopaedic principles, it provides enhanced support to help promote stable posture alignment and consistent comfort throughout the night. With 1200 individual pocket springs, each working independently, the mattress offers ultra-firm, personalised support that adapts to your body shape while reducing motion transfer between sleeping partners. The Firm e-Fibre™ comfort layer provides reliable firmness while still helping to ease pressure points. Finished in a soft knitted fabric, it is quilted with breathable Advance e-Fibre™ and features a 3D Mesh border to encourage airflow, for a fresh and comfortable sleep experience.

    Made by Jay-Be in the UK, the Flex mattress is made with a commitment to ethical and environmentally responsible practices. Manufactured using 100% certified renewable energy and zero-to-landfill processes, every component has been carefully selected for comfort, performance and end of life recyclability. For added convenience, the Flex is vacuum-packed and rolled to minimise packaging size and comes with a ten-year manufacturer’s guarantee for your extra peace of mind.

      So far so good

      Great being a rolled up mattress. Fully expanded after 24 hrs but slept on it after 6hrs. Abit firm for my liking but I am used to a sprung mattress. Fabric feels good quality

      Hugely recommend, your back will be thankful

      Great support, durable and great value for money, breathable and comfortable.

      Moving on from memory foam mattress keeps its shape do not dip easily, its structure is sustained, however comparing to the foam mattress there is noticeable audio notion under motion (but not unusual for spring mattress)
