High Resilient Comfort Foam Pillows

Classic foam or “high resilient density foam” and memory foam or “visco-elastic foam” is that they have different density characteristics and reaction to temperature. Classic foam will regain original shape instantly once pressure is removed and support with a constant amount of pressure relief over time. Temperature does not have a significant effect on this function using high resilient foam material. Memory foam however, will in comparison give way when pressurized and as a consequence not be as affective providing support which is why Royal Rest has cores made of high resilient foam in all pillows to provide for necessary support.
