Bonnell Spring Mattress Felt
Engineered non-woven needle-punched felt for durable Bonnell spring mattress construction.

The felt built for spring isolation
Bonnell spring units are robust but unforgiving — without a stable insulation layer, coil tips work through the upholstery over time. Our needle-punched non-woven felt sits directly against the spring unit, distributing load evenly and stopping wire breakthrough for the life of the mattress.
Overview
Product Overview
Our needle-punched non-woven felt is designed specifically to withstand the high compression and constant friction inside Bonnell spring mattresses. Engineered from high-tensile recycled textile fibres, it forms an outstanding barrier that prevents springs from piercing the upholstery.
With uniform fibre distribution and robust density control, this sustainable cushioning element enhances the insulation, ventilation and sound absorption of the final product, assuring high-end performance for mattress OEMs worldwide.

FAQ
Frequently Asked Questions
What GSM is recommended for standard Bonnell mattresses?
Most residential and contract manufacturers prefer 600 GSM or 800 GSM needle-punched felt. This provides the optimal thickness to completely isolate wires and cushion the spring movement under standard load conditions.
Can thickness be customised independently of GSM?
Yes. By altering the calendering heat profiles and mechanical fibre punch density settings, we can adjust the felt thickness profile to match your specific comfort-vs-rigidity guidelines.
Can you manufacture OEM products with our custom labels?
Certainly. We supply custom side label stickers, internal core prints, and roll sleeve branding for volume procurement orders.
Do you export internationally and handle customs packaging?
Yes, Tulsi Overseas is highly active in export markets. Every roll is securely wrapped in moisture-resistant heavy-duty PE film designed specifically to survive container transport and humid port layovers.
Can we request material samples before placing a bulk order?
Absolutely. We supply complimentary sample packs featuring our most common GSM ranges (400, 600, 800 and 1000 GSM) for physical compression and density testing in your engineering facilities.
