Open cell memory foam was developed to mitigate this very issue – and it has been successful to a varying degree. ), while lacking the viscoelastic qualities of memory foam, offers the same soft support but with a bit more spring. High quality viscoelastic foam – that is to say, with a density surpassing 4 lb./cu.ft., usually retains its conforming ability for much longer than other types of foam.
