muistikitti
Muistikitti, also known as memory foam, is a material that was originally developed by NASA in the 1960s to improve the safety and comfort of aircraft cushions. Its primary characteristic is its viscoelasticity, meaning it can deform under pressure and then slowly return to its original shape. This property allows it to conform to the contours of an object placed upon it, distributing pressure evenly.
The composition of memory foam typically involves a polyurethane base with added chemicals to increase its
Over time, memory foam transitioned from aerospace applications to consumer products. It is now widely used
