Qingdao Roadzeal Textile Co., Ltd is one of most professional and reliable hr foam top manufacturer and supplier in China。
In the high-end furniture and bedding industries, the internal support structure determines the lifespan and comfort of the final product. HR foam (High-Resiliency Foam) is a specialized grade of polyurethane foam defined by its unique cellular structure and high density. Unlike standard polyether foams, HR foam is manufactured using a specialized polyol and a “cold-cure” or high-performance molding process. This results in a material with an extremely high “Support Factor” (the ratio of compression) and a rapid rebound characteristic that mimics the buoyancy of natural latex.
Our collection of HR technical foams represents the “Gold Standard” for manufacturers who refuse to compromise on quality. Designed for high-traffic hospitality environments, luxury domestic furniture, and clinical pressure-relief systems, our HR foams provide the essential “push-back” support that prevents the sagging and “bottoming out” associated with lower-quality materials.
The performance of HR foam is fundamentally different from standard upholstery grades. We offer a curated range of densities, typically starting at 30 kg/m³ and exceeding 55 kg/m³, to achieve:
Differentiated Cell Structure: Our HR foam features a “random” or heterogeneous cell structure. Unlike the uniform cells of standard foam, these varied cell sizes act like thousands of tiny, independent springs, distributing weight more evenly across the surface.
High Sag Factor: HR foam typically has a sag factor (clamping force) of 2.4 to 3.0. This means the foam provides a soft initial touch but becomes significantly firmer as it is compressed, providing deep-seated skeletal support.
Instantaneous Recovery: With a nearly 98% recovery rate, HR foam returns to its original shape the moment pressure is removed. This prevents the “body impressions” that often plague memory foam mattresses.
Why do global luxury brands and contract furniture wholesalers specify our HR technical foams?
Unmatched Longevity: Standard foams lose their “loft” within 1–2 years. Our HR foams are engineered to maintain their original height and firmness for 10 to 15 years, even under constant daily use in hotel lobbies or high-end residential sofas.
Exceptional Breathability: The open-cell matrix of HR foam allows for significantly higher air permeability than memory foam. This facilitates the passive dissipation of body heat and moisture, maintaining a fresh and hygienic interior environment.
Hypoallergenic & Low-VOC: Our HR foams are manufactured using water-blown expanding agents. They are certified CertiPUR-US and OEKO-TEX, ensuring they are free from formaldehyde, phthalates, and heavy metals.
Fire Safety Compliance: We offer specialized HR grades that meet BS 5852 (Crib 5) and California TB117-2013 standards, making them suitable for commercial cruise ships, aircraft, and public institutions.
Our HR foam portfolio supports a wide array of high-performance, durable products:
As the primary “engine” of a premium mattress, HR foam provides the structural base that supports thinner layers of latex or memory foam. It ensures the mattress feels “new” for a decade, providing the orthopedic support required for healthy spinal alignment.
In the hospitality and office sectors, furniture must withstand 24/7 use. Our high-density HR foams are the preferred choice for ergonomic office chairs and theater seating, where durability and “sit-ability” are the primary KPIs.
For hospital beds and nursing home mattresses, HR foam is used to create “Zoned” support systems. By varying the IFD (firmness) in the head, torso, and heel areas, it helps prevent the development of Stage I and II pressure ulcers.
Due to its high tensile strength and resilience, HR foam is ideal for the rigorous environments of luxury yachts and premium automotive seating, where it must maintain its shape despite vibrations and temperature fluctuations.
We provide end-to-end technical support to ensure our HR foam integrates seamlessly into your production line:
Custom IFD (Firmness) Calibration: From “Cloud Soft” (15 ILD) to “Extra Firm” (50 ILD).
CNC Contour Cutting: Creating complex ergonomic shapes and “convoluted” surfaces for targeted airflow.
Lamination Services: Bonding HR foam to memory foam, felt, or high-performance fabrics using water-based, non-toxic adhesives.
While both have high weight per cubic meter, HR foam has a much higher “Support Factor” and “Resilience.” Standard HD foam can feel “stiff” or “dead,” whereas HR foam feels “springy” and “lively.” HR foam also has a much higher resistance to permanent deformation (fatigue) over time.
Yes. HR foam is often called “synthetic latex” because it mimics the buoyancy and durability of natural rubber at a more competitive price point. It is also significantly lighter than latex, which reduces shipping costs and makes final products easier to handle.
No. Because of its large, open-cell structure, HR foam is one of the coolest-sleeping synthetic foams available. It does not rely on body heat to “soften” (unlike memory foam), so air circulates freely through the material throughout the night.
Absolutely. Our HR foams are engineered with high tensile strength. They can be vacuum-compressed and rolled for up to 6 months without damaging the cellular structure, recovering to 100% of their size within hours of unboxing.
Genuine HR foam must have a density of at least 30 kg/m³ (preferably higher) and a sag factor of 2.4 or above. We provide technical data sheets (TDS) for every batch, detailing the density, ILD, and resilience ratings to guarantee authenticity.
