Details

The Flex Nube Junior Foam A kids mattress is a purpose-built sleep solution for active children and teenagers, inspired by one of Flex's best-selling adult models and reimagined for younger sleepers. Its Minipocket Spring core (8 cm) delivers point-by-point body adaptation that supports healthy spinal alignment throughout the night — a genuine benefit for growing bodies that need proper postural support during sleep.

The upholstery combines a heat-sensitive memory foam layer with hypoallergenic fibres and Confort System material on both faces of the mattress, creating a soft, progressive feel that is comfortable in any sleep position. The double-sided construction allows regular rotation for more even wear and a longer product life.

At just 20 cm in height, the Flex Nube Junior Foam A is slim enough to fit comfortably on bunk beds, cabin beds and even storage beds without raising the overall sleeping surface too high — while still delivering a level of sleep quality that goes well beyond what a standard children's foam mattress can offer. The pocket spring and breathable upholstery combination ensures continuous airflow inside the mattress, keeping the surface fresh and cool even during the warmest months — ideal for children who sleep warm or lead a high-energy daily life. Pairs perfectly with the Flex Nube Junior B (18 cm) for a fully matched bunk bed setup.
