Juna #4 – Built for Balance

Firm meets flexible.​ Performance Canvas Border Fabric What it is: A durable, high-airflow canvas side panel designed to reinforce the mattress perimeter and promote ventilation through the core. What it does: Adds structure for cleaner edge support, resists scuffs and sagging, and channels air in and out with every movement for better temperature regulation. Why it matters: Your mattress looks crisp and tailored, feels stable from edge to edge, and breathes more efficiently—extending comfort and longevity. Engineered for precision comfort. The Juna #4 delivers unmatched structural stability by adding a 2-inch high-density foam core beneath the 1,100 individually pocketed coil system with firmer edge support. Above the coils, it’s stacked with purple Energex™ for pressure relief, Hulk™ high-density foam for structure and durability, organic latex for breathable buoyancy, and gray Energex™ for a smooth finish. If you want a performance mattress that covers every base — this is it.
