Memory foam is a type of polyurethane foam that’s been treated with chemicals to give it special properties. It’s also known as viscoelastic foam, a moniker that accurately describes the way the material softens and contours in response to heat and pressure, gradually regaining its shape once heat and pressure are lifted.
Memory foam is popular in pillows because it molds to the head and neck, providing a supportive surface that can be shaped to the user’s liking. This close-conforming material is unrivaled in its ability to alleviate pressure points.
In this section, we’ll delve deeper into the pros and cons of memory foam and cover some of the most important aspects to look for when purchasing a memory foam pillow.
