Yes, that is true. I work in an industry that utilizes memory foam at every turn. Visco-elastic memory foam is not only a weight reactive foam but it is also a heat reactive foam. When the foam is cold it is hard and when it is warmer it is much softer..This type of foam like many others comes in different weights and different densities. The harder the foam the lesser the quality. The softer the foam the better the quality....Hope that helps...Happy Trekking...sabre11004...
