Office Chair Foam
The commonly used foam materials in office chairs are primarily high-resilience foam sponge and high-rebound (HR) foam plastic.

High-resilience foam sponge is a widely used material in office chairs, with its core performance indicators being rebound rate and compression set. Uniform cell structure and high open-cell ratio are the notable features of high-resilience foam sponge. This structure allows air to be quickly expelled under pressure and rapidly rebound to its original shape when the pressure is released, effectively reducing the problem of seat surface indentation after long-term use. Its stable molecular chain structure enables it to maintain a high rebound rate even during repeated compression, making it particularly suitable for office scenarios where the chair is used continuously for more than 8 hours a day, providing users with long-lasting support and comfort.
Soft polyurethane (PU) foam plastic is another common material, known for its lightweight and excellent elasticity, and is widely used in cushioning applications. With technological advancements, high-rebound (HR) foam plastic has become an important improved variety of soft PU foam plastic. It employs cold-curing molding technology, reducing the production cycle to 13 minutes and significantly improving production efficiency. Meanwhile, through optimization of synthesis routes such as polymer polyols and modified MDI, the rebound elasticity of the seat cushion is further enhanced, achieving a better balance between support and comfort.
The choice between the two types of materials should be based on specific needs: high-resilience foam sponge, with its stable molecular chain and uniform cell structure, is more suitable for scenarios with high durability requirements; high-rebound (HR) foam plastic, through process optimization, improves rebound performance while shortening the production cycle, making it suitable for scenarios that pursue efficient production and a comfortable experience. Regardless of the material chosen, the core goal is to optimize physical properties to meet users' comprehensive needs for seat support, comfort, and durability in office scenarios.
