There are significant differences in raw materials and performance between high rebound sponge (HR sponge) and memory foam (slow rebound sponge). The following is a detailed comparison:
3. Application scenarios
High rebound sponge: sofas, car seats, mattress surfaces (need fast rebound and long-term support).
Memory foam: pillows, mattresses, medical protective gear (need decompression and fit the body).
4. Selection suggestions
Seeking support and durability: choose high rebound sponge.
Need decompression and comfortable fit: choose memory foam.
Although the two materials are both polyurethane, the differences in formula and process create completely different performances. You can choose according to your needs.
