Serta typically does not provide information about the quality of materials used in their foam mattresses. We do not recommend buying a foam mattress unless you know the height, density or ILD of each layer this mattress was built with. Height and density of a foam layer determines the quality and durability of this layer. Overall quality and durability of the mattress is only as good as the quality and durability of its components.
