The Momentum Firm features various cooling properties such as a cool to the touch cooling cover and gel infused memory foam. Ultra support foam provides more support and gives it a more firm feel. Quantum pocketed coils provide good support and they move independently from one another. This prevents a "dip" in the mattress and better weight distribution. Active edge protection keeps the shape of the coils and gives the mattress more longevity.
