Being in the furniture components industry since 1986, we have seen it all. We are very familiar with BIFMA testing. We even developed our own caster impact test in 1991. Our caster impact test was adapted by major office chair manufacturers such as HON and Globe to name a few.
100% of our products are made in Taiwan. We are proud of our quality as well as customer service and quick shipping.
We use 100% nylon 6 for our casters (not PP) and nylon 6/6 with 33% fiber glass for our nylon chair bases. Stems are zinc plated to prevent rust. Aluminum bases are deburred at the edge and hand polished. Quality checks are in place at each stage of production from incoming raw material, initial injection molding, shift testing to final packaging.
All these parts are functional parts, without them the end products just won't work. Cheap parts save you a few bucks now but causes personal injury and liability. It's more economical to buy quality parts in the long run.
You can buy cheaper but you can't buy better value. Let us prove it to you.
