Little Luuf Youth 9" Hybrid Full Mattress delivers balanced, medium support tailored to growing sleepers, combining a pressure-relieving memory foam layer with durable polyurethane comfort for consistent cushioning. Its hybrid construction pairs those foam layers with a responsive support core to promote alignment and reduce motion transfer, while the cooling cover helps regulate temperature. Shipped as a Bed In a Box and made in the USA, it sets up quickly and works with standard foundations or a box spring for stable support and lasting performance.
