Memory Foam vs. HR Foam: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on February 2, 2024
Memory Foam is a viscoelastic material known for its ability to contour to the body, while HR Foam (High Resilience Foam) is a more responsive, durable polyurethane foam.

Key Differences

Memory Foam, developed by NASA, is recognized for its pressure-relieving properties and ability to mold to the body in response to heat and pressure. HR Foam, standing for High Resilience Foam, offers higher resilience and bounces back to its original shape more quickly than Memory Foam.
The density of Memory Foam allows it to absorb motion, making it a popular choice in mattresses for reducing partner disturbance. In contrast, HR Foam is appreciated for its supportive properties and durability, often maintaining its shape and firmness over time.
Memory Foam is temperature-sensitive, becoming softer and more pliable with body heat, which can be an issue in hotter climates. HR Foam is less affected by temperature, maintaining a consistent feel regardless of the environment.
Memory Foam provides a unique sinking feeling that envelops the body, often preferred for its comfort in bedding products. HR Foam, on the other hand, is more commonly used in furniture and seating due to its ability to recover quickly from compression.
When it comes to maintenance, Memory Foam requires more careful handling as it's prone to damage from excessive weight or pressure. HR Foam is generally more robust, resisting wear and tear and retaining its structural integrity over time.
