The Flex Garbí Foam Adjustable mattress is specifically engineered for use on adjustable beds, combining a profiled foam core with a gel memory foam comfort layer to deliver a firm yet adaptive sleep surface that performs exceptionally well across all articulation positions. Recommended for sleepers up to 95 kg.
At its heart lies a 15 cm AirVex® NxT high-density foam core, made from natural materials whose unique microsphere structure creates millions of natural micro-channels throughout the block. Together with vertical and horizontal ventilation channels built into the core itself, these micro-channels generate outstanding internal airflow — keeping the mattress fresh, dry and well-ventilated night after night.
The 7 differentiated firmness zones moulded directly into the core ensure that each area of the body receives precisely the right level of support, promoting healthy spinal alignment and minimising pressure build-up at the hips and shoulders. The gel memory foam upholstery adds a pleasant, cushioning surface feel and a subtle cooling sensation on contact, without compromising the overall firm character of the mattress.
The Optigrade® outer fabric actively distributes surface temperature for a consistently comfortable sleep environment, while the book-opening zip cover makes removal and cleaning straightforward — contributing to a noticeably more hygienic sleep surface over time. Part of the Flex Ultimate range, with free delivery, assembly and removal of your old mattress included.
