mattress inner spring price

The price of mattress inner springs is primarily driven by wire gauge (thickness), coil count, and spring type. For high-end mattresses, look for 12.5 to 15-gauge steel wire; a lower gauge indicates a thicker, firmer spring. The coil count directly impacts support—standard queen units typically range from 600 to 1,000 coils. Additionally, ensure the steel has undergone high-temperature heat treatment (tempering) to prevent sagging and ensure long-term shape retention.

Bonnell coils are the most cost-effective and traditional, ideal for budget-friendly or promotional bedding. Pocket springs (Individually Wrapped) are the premium choice, offering superior motion isolation and higher profit margins, though they typically cost 20-40% more than Bonnell units. Continuous coils offer a middle ground in terms of durability and price, often used in hospitality-grade mattresses for their robust structural integrity.

Suppliers should provide certification for ISO 9001 Quality Management Systems. For the steel itself, request tensile strength test reports to ensure the wire won't snap under pressure. If the springs are pre-assembled into units with foam or fabric, ensure they meet flammability standards such as CFR 1633 (US) or BS 7177 (UK). For eco-conscious markets, verify that the steel is recyclable and free from heavy metal coatings.

Mattress springs are bulky, so compression and roll-packing are essential to reduce shipping costs. High-quality springs should be able to withstand vacuum compression for up to 6 months without losing more than 2% of their height. To maximize container utilization, source from manufacturers on Made-in-China.com who utilize automated compression machinery, allowing you to fit up to 300-500 units per 40HQ container depending on the spring type.

The most significant risk is oxidation and rusting during sea transit due to high humidity. Ensure the supplier uses anti-rust oil coating and VCI (Vapor Corrosion Inhibitor) plastic packaging. Another risk is height deviation; always specify a tolerance of +/- 5mm in your purchase contract to avoid assembly issues in your mattress factory.

Negotiate based on the current market price of steel wire, as this is the primary raw material cost. Request a tiered pricing structure where the unit price drops by 5-10% when ordering full container loads (FCL). On Made-in-China.com, look for 'Diamond Members' or 'Audited Suppliers' and ask for a sample of the specific wire gauge before committing to a bulk order.

Utilize Secured Trading Services provided by reputable platforms to hold payments in escrow until the bill of lading is issued. Conduct a pre-shipment inspection (PSI) to verify the coil count and wire diameter match the proforma invoice. Never transfer 100% of the payment upfront; a standard 30% deposit and 70% balance against the copy of the B/L is the industry norm for reliable B2B transactions.

Because steel springs are extremely heavy, ensure your local warehouse has heavy-duty forklifts capable of handling palletized spring units. Confirm the Incoterms clearly; FOB (Free On Board) is recommended for experienced buyers to maintain control over freight costs, while CIF (Cost, Insurance, and Freight) may be easier for first-time importers. Always include marine insurance to cover potential damage during rough sea transit.
