what is the difference between medium and high density foam?
Many conventional foams have a density between 1LB and 3LB. However, the densest materials can be as much as 10 or 15LB. High-density foam, Like The Foam Factory's 2.8LB density HD36-HQ foam, is optimal for uses that receive heavy or daily use like couch cushions, bedding, or automobile seating.
