Short, concrete pieces for importers and contract buyers — EN 1335 types and durability, the European compliance stack, mechanism tuning and the trade-offs we argue about with buyers. No fluff, no fabricated certificates.
German buyers do not just ask whether a chair passes the test. They ask for the GS mark — a different animal: type testing plus chemicals plus a factory inspection, with the badge owned by whoever holds the certificate. Here is the process from our side of it.

European buyers have started scoring chairs on whether they can be repaired, not just whether they survive. A serious parts program is cheap to set up at order time and expensive to improvise in year four. Here is how we structure one.

A chair can pass every strength test and still get rejected for sitting 10 mm outside its EN 1335 type band. Here is how the dimensional types work and how we pin yours down.

EN 1335-2 is written around an assumed 8 hours of daily use. That single assumption decides which gas column, base and mechanism we put under your chair.
Read the noteA synchro mechanism is only as good as its tuning. Get the 2:1 ratio and the tension range wrong and you ship a chair that either throws people backwards or will not recline at all.

A European contract order is not one requirement, it is three stacked: the chair standard, the chemistry, and — for upholstery — fire. Miss any one and the shipment can be rejected at the door.
Read the noteA contract chair is sat in by people of every size. The adjustments are not features to upsell — they are what stops one chair being wrong for half the floor.
Read the noteFor a fit-out the choice is not taste. Mesh and upholstery fail differently, clean differently, and carry very different fire requirements — and that decides the order.

A "5-year warranty" line means nothing until you read what it covers, for how many hours of use, and who ships the spare part. Here is how we write one that holds up.
