Flex Teknia Foam Mattress
AirVex® foam and memory foam mattress by Flex | Firmness: Medium
Details
The Flex Teknia Foam mattress is the ideal solution for those looking for a memory foam comfort layer combined with a high-performance foam core. At its heart lies AirVex® — a high-density foam developed exclusively by Flex, built from millions of interconnected microspheres that form natural ventilation channels throughout the core. The result is a material that is both dense and exceptionally breathable, providing a firm, reliable base with a very high level of airflow for a consistently fresh night's sleep.
This combination delivers a mattress with a medium firmness that feels supportive yet adaptive on the surface — responsive enough to accommodate different sleep positions while maintaining the structural integrity that quality sleep requires. The double-sided symmetric construction means both faces of the mattress are identical, allowing you to rotate it regularly for more even wear and a longer useful life.
The Optigrade® Stretch outer fabric completes the package with a pleasant, high-quality feel and an active temperature regulation system that disperses heat build-up at the surface, preventing that uncomfortable warm sensation and keeping the sleep environment fresh from start to finish. With its book-opening zip cover for easy removal and a construction specifically engineered for use on adjustable bases, the Flex Teknia Foam is a particularly strong choice for those with an articulated bed frame. Part of the Flex Selection range, with free delivery, assembly and removal of your old mattress included.
