Memory Foam vs. HR Foam — What's the Difference?
By Tayyaba Rehman — Published on January 19, 2024
Memory Foam is a viscoelastic material that molds to the body in response to heat and pressure. HR Foam, or High Resilience Foam, is more responsive and bounces back to its original shape quickly.

Key Differences
Memory Foam, developed by NASA, contours to the body, providing excellent support and pressure relief. HR Foam, known for its high resilience, offers a firmer support and quickly returns to its original shape after pressure is removed.
Memory Foam's temperature sensitivity allows it to adjust to the sleeper's body heat and weight. HR Foam, however, is less affected by temperature and provides consistent support regardless of heat or cold.
Memory Foam is often used in mattresses and pillows for its ability to reduce pressure points. HR Foam is preferred in sofas and furniture for its durability and ability to maintain shape over time.
The slow recovery time of Memory Foam creates a 'sinking' feeling, which some find comfortable for sleeping. HR Foam responds more rapidly, offering a more supportive and less enveloping feel.
Memory Foam is suitable for those who prefer a softer, contouring sleep surface. In contrast, HR Foam is ideal for those who require firmer support, such as in seat cushions and firmer mattresses.
