Memory foam is made of polyurethane with some additional chemicals to increase its viscosity and density and is often referred to as Visco elastic polyurethane foam.
In higher density memory foam body usually react to heat in which allowing it to mold to a warmer human body in a few minutes, where as in low density foam, the pressure sensitivity molds quickly to the shape of the body where in you feel comfortable and feeling soft.
The benefits you can get in Visco memory foam mattress pad is that the Visco elastic material which are used allows mattress toppers to conform body curves to relive pressure points. Usually other mattresses when you sleep on one side, you can feel there is pressure on your shoulder, hips and knees where in you cannot have a nice rest while sleeping and as you wake up, you can feel some aches or pain on your body.

This kind of foam the Visco memory foam has no dangerous residues although TDI is used in the sleep aid production process. Remember that most foam used DTI in their processing the foam and after the processing, DTI residue is finished due to the fact that during the production process it is already consumed.
What is good in Visco memory foam mattress pad is that, it has a higher resistance that when you apply pressure it feels firmer and foam will slowly compress under your body weight with the aid of your body heat and once it is compressed, it can hold its compressed shape and slowly returning to normal. In theory, the slower the changes back to normal, the better the quality of the mattress pad.
Take note, not all pads are made equal, since in low cost suppliers, they may use harmful chemicals such as formaldehyde in producing their foam. It also vary on how slow there spring back to normal and how sensitive they are to your body temperature.
Even though Visco foam mattress pad are invented by NASA but NASA haven't actually uses the product but medical companies realized that using the Visco foam mattress pads works wonders to relieve pressure points.
