Description

The firm choice for firm support If you’re looking for a firmer mattress, the Jay-Be Flex Ultra-Firm is specially engineered with orthopaedic principles in mind. Its high-tension spring core provides ultra-firm, resilient support to help maintain stable posture throughout the night. A Firm e-Fibre™ premium comfort layer offers a firm, yet pressure-relieving foundation for added comfort. To help keep you feeling fresh, the Flex is finished with a top layer breathable Advance e-Fibre™, offering a softer sleep surface which enables airflow, to help moisture evaporate for a more comfortable sleep environment. Every feature of the Flex mattress has been carefully considered with comfort, well-being and sustainability in mind. It is made in Jay-Be’s UK factory, which is powered by 100% certified renewable electricity and operates a zero-to-landfill policy. For added convenience, the mattress is vacuum packed and rolled, and comes with a ten-year manufacturer’s guarantee, offering long lasting peace of mind.
