The Helix Kids Mattress is an innovative, award-winning mattress specifically made for growing kids. The mattress features a 2-sided design with a firmer side for children aged 2-7 who need more support as they grow. When they're ready, just flip it to the softer side, with a memory foam comfort layer, which we recommend for children ages 8 and up. This mattress includes kid-friendly features including a hypoallergenic TENCELT cover, a plant-based water-repellent, and a hygienic microbe shield. The Helix Kids Mattress is built with steel coils to provide stability, edge support, and long-lasting durability.
