Memory foam derives its viscoelastic properties from several effects, due to the material's internal structure. The network effect is the force working to restore the foam's structure when it is deformed. This effect is generated by the deformed porous material pushing outwards to restore its structure against an applied pressure. Three effects work against the network effect, slowing the regeneration of the foam's original structure: Web10 mei 2024 · Memory foam density: Low density: Less than 3.5 pounds per cubic foot Medium-firm (medium-density): Between 3.5-4 pounds per cubic foot High Density: Greater than 6 pounds per cubic foot High-density memory foam has several pros and cons and isn't the best option for the wider population.
