Memory Foam vs. PU Foam: Know the Difference
By Shumaila Saeed || Published on February 23, 2024
Memory foam is a viscoelastic material that contours to the body and slowly returns to its original shape, while PU (polyurethane) foam is a more common, less dense foam used in a variety of applications.
Key Differences
Memory foam, developed by NASA, is known for its slow response to pressure and ability to contour closely to the shape of the body, providing excellent support and pressure relief. PU foam, or polyurethane foam, is a more common foam used in a variety of applications, known for its lightweight and supportive characteristics but without the contouring feature of memory foam.

The unique property of memory foam is its temperature sensitivity, allowing it to soften and mold with body heat. PU foam, on the other hand, does not have significant temperature sensitivity and maintains a consistent feel regardless of temperature.

Memory foam is often used in mattresses, pillows, and orthopedic products due to its ability to distribute weight evenly and reduce pressure points. PU foam is widely used in furniture, car seats, and packaging, providing firm support and resilience.

In terms of durability, memory foam tends to last longer and retains its shape better over time compared to PU foam, which may degrade or lose its firmness more quickly. However, memory foam is also more expensive than PU foam, reflecting its enhanced qualities and longevity.

Memory foam's dense structure can sometimes retain heat, which some users find uncomfortable. PU foam, being less dense, generally allows for better air circulation and does not have the same heat retention issue.
