Mattress and upholstery production needs flexible, breathable and odourless bonds. Because the end user is in direct, prolonged contact with the product, adhesive choice also matters for comfort and health.
Pocket spring mattresses
Springs in fabric pockets are bonded side by side with hot melt to form a spring unit. The adhesive must set fast, stay flexible and move with the springs. EVA and PO hot melts are the standard. To join the unit to foam and felt layers, spray hot melts or SBS/SIS spray adhesives are used.
Foam mattresses and layered builds
Foam layers of different densities need a breathable bond. Spiral or fibre spray patterns keep air permeability while bonding strongly.
Upholstered furniture
- Foam to timber frame: SBS/SIS or CR contact adhesives
- Foam to foam: spray adhesives, flexible and low-odour
- Fabric to foam: PO or PUR hot melt lamination
- Fibre and wadding: PSA hot melts
What to watch
| Criterion | Why it matters |
|---|---|
| Flexibility | A hard glue line spoils comfort and can be felt |
| Odour | End-user satisfaction in enclosed spaces |
| Open time | Enough time to position large parts by hand |
| Consumption | The biggest cost item over large areas |
| Emissions | Low VOC for indoor air quality |
From solvent-based to hot melt
Many manufacturers are switching from solvent-based sprays to hot melt sprays to cut VOC emissions and eliminate drying time, gaining a cleaner workplace, instant bonding and storage advantages.
