What to ask a supplier before comparing prices
A price per kilogram says little about the cost of a bonded mattress. Start with questions that show whether the supplier understands your construction and your process, not only its own catalogue.
- Which mattress constructions do they already support: foam layers, latex, fibre pads, quilted covers, pocket springs or bonded edges?
- Which application methods do they know on your line: spray, roller, slot die or hand application?
- What do they need from you to recommend a product: substrates, open time, line speed, ambient conditions, required bond strength and cleaning routine?
- Can they explain why a given chemistry suits your case, and when it would not?
- Who handles technical questions after the sale, and in which language and time zone?
A supplier who recommends a product without asking about your substrates and process is guessing. Good answers are specific and include limits as well as strengths.
Selection criteria that matter in mattress production
Compare suppliers against the same written requirements. The table below can serve as a starting scorecard; adapt the weighting to your product range.
| Criterion | What to check |
|---|---|
| Adhesive family fit | Whether the proposed chemistry suits your substrates and equipment, for example hot melt adhesives or water-based adhesives, and what each means for drying, heating and handling |
| Process window | Open time, tolerance to temperature and humidity changes, and behaviour when the line stops and restarts |
| Bond performance | How the bond is tested and how results are reported, including the failure mode |
| Fire-related requirements | Whether the supplier understands the fire tests your market applies to finished mattresses and can discuss how the adhesive may influence results |
| Handling and workplace | Odour, ventilation needs, storage conditions and cleaning method |
| Support | Technical contact, response times and willingness to visit or test on your line |
Look beyond the peel value itself. In foam peel testing, a bond can fail in three ways: a clean separation at the interface between foam and adhesive, a split within the adhesive layer or the foam, or a tear within the foam itself. [1]
If the foam tears while the interface stays intact, the bond has proved stronger than the foam under those test conditions. Two constructions with similar peel numbers can therefore perform differently, so ask suppliers to report the failure mode alongside the figure. [1]
Documents to request
Ask for documents early, before samples are shipped. A supplier that hesitates to provide them at the quotation stage is unlikely to become more open later.
- Technical data sheet for each product, with application method, substrates, open time, curing or drying behaviour and storage conditions.
- Safety data sheet in the language of the country of use, issued in the current format. Check that it is dated and that the product name matches the quotation.
- Statements on any restricted substances or emissions requirements your customers impose. Ask the supplier which of these it can document and how.
- Information on how the adhesive may affect fire-test results of the finished mattress. One relevant method is a test for ignitability of mattresses, upholstered bed bases and mattress pads using a smouldering cigarette as the ignition source. Ask which test reports, if any, the supplier can share and on which constructions they were made.
- Shelf life, batch numbering and the certificate of analysis or conformity that accompanies deliveries.
- Change notification policy: how and when customers are told about formulation or raw material changes.
Test reports from other customers' constructions do not automatically apply to yours. Ask the supplier to state clearly what was tested and under which conditions.
Logistics and supply continuity
Adhesive is a small share of mattress cost but a stoppage in supply can halt a whole line. Assess continuity as carefully as technical fit.
- Ask where the product is made and stored, and whether more than one site can supply it.
- Ask how raw material shortages have been handled in the past and whether alternative formulations are approved in advance.
- Agree pack sizes that match your consumption and storage space, and check handling requirements such as pallet type or equipment for bulk containers.
- Clarify the ordering process: lead times for standard and urgent orders, minimum quantities, and who to contact when a delivery is late.
- Check storage and transport conditions, particularly for products sensitive to heat or frost, and what happens to product that arrives outside them.
- Discuss buffer stock or consignment arrangements and who bears the cost.
Because lead times and capacity are commercial commitments, get them in writing and compare them with your own planning horizon rather than relying on verbal assurances.
How to run a supplier trial
A trial should answer a defined question: does this adhesive meet our requirements on our line, with our materials, at acceptable cost? Without defined criteria, trials often end with opinions instead of data.
- Write acceptance criteria before starting: bond performance, appearance, application consistency, odour and operator feedback.
- Use production materials from current stock, not special samples prepared for the trial.
- Keep the existing adhesive as a reference and test both under the same conditions and on the same days.
- Record application settings, ambient conditions, open times and batch numbers so results can be traced.
- Test bonds at different times after production and after realistic storage or handling, not only immediately.
- Record the failure mode for every test, not only the numerical value.
Involve the production team and quality department from the start. Operators notice practical problems, such as stringing, clogging or cleaning difficulty, that a laboratory result will not show. Finish with a short written review and agree what a second, larger trial would need to prove before any switch.
Warning signs when evaluating a supplier
- Claims of suitability for every mattress construction with no questions about yours.
- Reluctance to supply technical and safety data sheets before an order.
- Test results quoted without describing the method, the substrates or the failure mode.
- Vague answers on supply sources, lead times or change notification.
- No named technical contact, or support available only through a sales channel.
- Pressure to commit to volumes before a trial is complete.
- Documents with missing dates, inconsistent product names or revisions that do not match the quotation.
One warning sign is not necessarily disqualifying, but several together suggest a supplier that will be hard to work with when a problem occurs. For a wider view of the product range and how adhesive families differ, see the overview of industrial adhesives.
