The Helix Kids Mattress is our innovative, professionally endorsed mattress specifically designed for growing kids. The mattress features a 2-sided design with a firmer side for children aged 37 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 8-12. The Helix Kids Mattress is built with steel coils to provide stability, edge support, and long-lasting durability.
