What Is Memory Foam?
First developed in the mid-1960s for NASA airplane seats, memory foam is made from a substance called viscoelastic. It is both highly energy absorbent and soft.
Memory foam molds to the body in action to heat and pressure, uniformly dispersing body weight. It then goes back to its initial shape once you eliminate the pressure.
In addition to protecting against impact, these residential or commercial properties make memory foam extremely comfortable. After its “virgin flight” for NASA, memory foam made a venture into other applications. It was used as cushioning in helmets and shoes. Medicine found a use for it in prosthetics and products to prevent pressure ulcers such as seating pads for individuals who are significantly disabled.
Then, memory foam really removed. It’s now well known for its use in pillows, mattress pads, and mattresses, which can be found in different densities and depths.
What Are the Advantages of Memory Foam?

Gromer says that memory foam products might retain temperature, which could make them less comfy in warm weather condition. However, Arand has not heard this problem from her clients. “In our culture, the majority of people can adjust their thermostats or blankets for the appropriate season,” Arand says.
When brand-new, memory foam can produce an odd chemical odor– a phenomenon called offgassing. To reduce this problem, the Sleep Products Security Council, a sleep items trade group, suggests airing out the mattress or pad for a minimum of 24 hr before putting sheets on it. “If you follow instructions, the odor dissipates quickly,” Arand says, “But I’ve never ever become aware of anybody having reactions to it.”
