Breathable foam comfort layers promote increased air circulation, further enhancing the cooling effect and overall sleep freshness. Medium-firm comfort level offers the perfect balance of plush cushioning and supportive firmness for pressure point relief and back support. Certified foam materials are used in construction, ensuring a safe sleeping environment free from harmful chemicals and odors. Hybrid design merges the classic support of an innerspring system with the modern pressure relief of advanced foam for the best of both worlds.
