Qingdao Roadzeal Textile Co., Ltd is one of most professional and reliable premium spring mattress topper top manufacturer and supplier in China。
The spring mattress remains the cornerstone of the global bedding industry, valued for its unparalleled breathability, reactive support, and structural longevity. While the basic concept of using steel coils for suspension dates back over a century, modern spring technology has undergone a radical transformation. Today’s high-performance spring mattresses are precision-engineered systems that combine high-tensile steel alloys with advanced comfort layers to provide a “weightless” sleep experience.
In this collection, we feature a diverse range of spring architectures—from traditional Bonnell coils known for their durability to state-of-the-art Individually Pocketed Springs and Hybrid models. Whether you are a hotelier seeking a 10-year investment or a homeowner looking for the perfect balance of bounce and pressure relief, our spring collection is built to exceed international standards.
The “feel” of a spring mattress is dictated by how the coils are interconnected. We offer two primary engineering styles:
Individually Pocketed Springs (The Luxury Standard): Each coil is encased in its own non-woven fabric sleeve. Because the springs are not wired together, they move independently. This allows the mattress to contour to your body’s specific curves and—most importantly—eliminates motion transfer between partners.
Bonnell and Offset Coils (The Durable Classic): These feature an hourglass shape and are interconnected by a helical wire. This creates a highly stable, “active” support system that is ideal for those who prefer a firmer feel and for high-traffic hospitality environments where durability is the priority.
A human body is not a uniform weight. Your hips and shoulders require different levels of resistance than your head and feet. Our premium spring mattresses utilize Multi-Zone Coil Arrays:
Lumbar Reinforcement: We use a thicker gauge of steel wire (e.g., $2.3\text{mm}$) in the center third of the mattress to prevent the spine from sagging.
Shoulder Comfort Zones: More flexible coils (e.g., $1.8\text{mm}$ to $2.0\text{mm}$) allow the shoulders to sink in slightly, preventing the “pins and needles” sensation for side sleepers.
Edge Support Technology: Every mattress in this collection features a reinforced perimeter, either through thicker coils or a high-density foam encasement, ensuring you don’t feel like you are “sliding off” when sitting on the edge.
The inherent advantage of a spring mattress over a solid foam bed is its massive internal air volume.
The Chimney Effect: The hollow interior of the spring unit acts as a natural ventilation chamber. With every movement you make, warm air is pushed out of the mattress and cool air is drawn in.
Thermal Regulation: When combined with our open-cell comfort foams or 3D POE mesh layers, the spring core facilitates a constant microclimate, keeping your body temperature neutral throughout the night.
To provide the “cloud-like” comfort of foam with the “push-back” support of steel, we offer advanced hybrid spring mattresses:
TPE/POE Grid Layers: We integrate Thermoplastic Elastomer (TPE) grids above the spring unit. These columns buckle under pressure points (hips) while remaining firm under the lumbar, providing a dynamic response that foam alone cannot match.
High-Density Transition Foams: Between the spring core and the quilted top, we use high-density polyurethane ($30\text{kg/m}^3$ to $50\text{kg/m}^3$) to ensure you never “feel the coils,” creating a seamless, luxury sensation.
As a professional manufacturer, we utilize high-carbon, double-tempered steel for all our spring units.
Fatigue Testing: Our springs undergo “Rollator” testing, simulating 100,000 cycles of usage to ensure they maintain their height and tension for over 10 years.
Corrosion Resistance: Our coils are treated with a specialized coating to prevent rust and degradation, even in humid coastal climates.
Certifications: All comfort layers are CertiPUR-US® certified, and our spring units meet international flammability standards including CFR 1633 and BS 7177.
Coil Count refers to the number of springs (e.g., 800 or 1,000 in a Queen). While important, Coil Gauge (the thickness of the wire) is often more critical for support. A lower gauge number (like 13) indicates a thicker, firmer wire, while a higher gauge (like 15) indicates a thinner, more flexible wire.
Yes! We use advanced hydraulic compression technology to flatten and roll our spring mattresses. Because we use high-tensile, double-tempered steel, the coils “snap” back to their original height immediately upon unboxing without any loss of structural integrity.
A high-quality spring mattress with a pocketed coil system and high-density foam layers typically lasts 8 to 12 years. To maximize longevity, we recommend rotating the mattress 180 degrees every 6 months to ensure even wear across the coil unit.
Traditional interconnected (Bonnell) springs can transfer motion. However, our Pocket Spring models are specifically designed to eliminate this. Each spring reacts independently, so your partner’s movements on their side of the bed will not be felt on yours.
Spring mattresses are versatile. They work perfectly on a solid platform, a slatted frame (with slats no more than 3 inches apart), or a modern foundation. For our hybrid models, a sturdy, non-flexing surface is recommended to provide the best support for the heavy foam layers.
