Memory Foam Manufacture & PerformanceMartyn Bodymould
How does Memory Foam work?
Unlike standard foams that compress and spring back to their original shape immediately, Memory Foam takes much longer to recover (slow recovery foam as it is sometimes known). This is because the cells within the Memory Foam spread air to surrounding cells, decreasing the pressure you feel when you lie on it.
This accounts for the way that Memory Foam actually reduces pressure points. It’s this ability to deform that allows Memory Foam to adapt to your body’s shape and weight-bearing areas. No other material has the unique ability to shape to your body in the way that Memory Foam does.
What works best?
However, although Memory Foam is incredibly versatile, an entire mattress made of Memory Foam would be far too soft for us to sleep on. It works best when layered over a firm, supportive material (which is why our Memory Foam mattress toppers are ideal).
Because of this effective combination of materials, Memory Foam is generally used as a 2″ or 3″ topper to be used on your existing, firm mattress. If you are buying an entirely new mattress, you’ll find a 2″ or 3″ topping layer, bonded to a thicker layer of polyurethane Reflex foam, offers support and works in harmony with the Memory Foam layer.
Why Memory Foam?
Memory Foam is sensitive to changes in temperature. At lower temperatures it is firmer (more viscous), and at higher temperatures it is softer and more elastic. This is the reason Memory Foam is sometimes referred to as visco-elastic memory foam. This temperature sensitivity accounts for the ‘melting’ feeling you sometimes get when you lie down on Memory Foam. It also accentuates the moulding effect of the foam.
