An egg crate mattress (usually sold as a topper) is a foam pad named for its textured, repeating pattern of peaks and valleys, which strongly resembles a cardboard egg carton. Made from either polyurethane or memory foam, it is designed to increase airflow and relieve pressure points.
The peaks of the foam compress under heavy parts of your body (like your shoulders and hips), while the valleys support lighter areas. This helps reduce aches and distribute weight evenly.I
The channels or “grooves” between the bumps allow air to circulate freely beneath your body, making it a popular choice for hot sleepers.
It is a relatively inexpensive way to soften a mattress that feels too firm.
Common Uses: Egg crate foam is rarely used as a standalone mattress. Instead, it is typically used as a mattress topper placed directly on top of a standard bed, futon, or sofa bed. It is also highly portable, making it a staple in college dorms, on camping cots, and for travel.
