1、The wire of 2.4mm high-carbon steel was used for the production. The wire is continuously wound into the coils without the formation of knots or sharp bends which means that the stress points are not there.
2、Springs are heated and cooled at a very high temperature to eliminate the internal stresses. This results in 30% more rebound capacity, no deformation or sagging even after long-term use.
3、Edge reinforcements are made of the 4.0-5.0mm thick steel wire. They provide very good resistance to compression.
Product Introduction:
One of the biggest worries for people buying spring mattresses is spring fatigue and the spring losing their original shape time after time - more so when the spring constantly compressed in the mattresses or chairs that are used a lot. Springs that are not fully relieved of the internal stresses, result in the loss of their ability to rebound, meaning the mattress will eventually sag, provide less support, and fail prematurely.
Our High Tensile Bonnell Spring System works on this problem by using 2.4mm high-carbon steel wire that is very precisely engineered, continuously wound without knots or sharp bends - thus, stress points are eliminated right from the beginning. Next, the springs are subjected to extremely high-temperature heating and cooling to completely release the internal stresses, resulting in 30% more rebound capacity. Designed to maintain its shape even with daily use. Besides that, the 4.0–5.0mm steel edge reinforcements offer amazing compression resistance, which ultimately ensures that the structure will remain intact and the performance will be long-lasting - something your B2B clients will definitely be able to rely on.
Product Advantages Comparison
| Feature | Our High Tensile Bonnell Spring System | Typical Competitor Products |
|---|---|---|
| Wire & Coil Structure | Single high-carbon steel wire, continuously wound for even force distribution and stable support | Multiple wire segments or lower-grade steel, leading to inconsistent tension and weak spots |
| Knots & Stress Points | Knot-free design eliminates stress concentration points | Knots or sharp bends create stress points that accelerate fatigue |
| Heat Treatment | Comprehensive heat treatment process ensures structural integrity | Minimal or no heat treatment, resulting in higher height loss over time |
| Height Loss After 100,000 Cycles | Less than 2% – maintains original shape and support | Often 5–10% or more, causing premature sagging |
| Edge Reinforcement | 4.0–5.0mm thick steel wire for superior compression resistance and durability | Thinner or weaker edge wire, prone to deformation under heavy load |
| Breathability | Large open spaces between coils promote excellent airflow | Dense or closed coil patterns trap heat and moisture |
| Production Process | Well-established and economical – optimized for large-scale purchasing and project installations | Inconsistent or less efficient production, leading to higher costs and longer lead times |
| Overall Durability | No deformation or sagging even after long-term, heavy use | Gradual loss of support, requiring earlier replacement |
