Memory foam was originally developed in the 1960s by NASA for use in aircraft cushions to improve safety and comfort during flights. The material is made from viscoelastic polyurethane, which allows it to conform to the shape of an object and return to its original form. Over time, it transitioned from aerospace applications to consumer products, including mattresses and pillows, due to its supportive and pressure-relieving properties. Today, it is widely used in various products for enhanced comfort.
Visco elastic memory foam mattress toppers come in a variety of sizes, such as to fit a single bed. Similarly, they do toppers for double beds, king and queen sizes too.
Memory foam is made up of a polyurethane foam material with is molded into a form of a mttress, pillow, and so on.
High density foam is just your typical foam. It does not conform to your body when it heats up like memory foam does.
Instead of purchasing a complete cushion made out of memory foam, it is possible to add one or two memory foam toppers to a regular foam cushion. This will give the support but will not be as hot or as prone to permanent indentations as memory foam.
The truthful answers is: "It's the thickness you are willing to pay for". One manufacturer I know of makes memory foam mattresses in three configurations: The top 2" of the mattress is memory foam, the top 4" is memory foam, and the whole mattress is memory foam. The price varies accordingly. Personal Note: If you can't afford a memory foam mattress, try a memory foam pillow. Awesome, especially if you're a "side sleeper".
