Chair leg components

Beyond the headline knock-down foot, we make the everyday leg parts a chair factory orders by the thousand — welded tube spiders, bare castings, and round-tube knock-down legs.

Pick the build to the price

Not every chair needs a polished casting. A welded square-tube spider hits a lower cost for office volume and still uses our screwless hub at the centre. A bare cast leg ships without castors for buyers who fit their own wheels. And the round-tube knock-down leg keeps the flat-pack benefit when you want a tube look rather than a casting.

All three accept standard castors and a standard gas lift. We would rather match the leg to what the chair actually needs than push the most expensive option — that is the difference between buying from a component maker and a catalogue reseller.

Common questions

Do legs come with castors fitted?
Your choice. We supply legs with castors fitted, with loose castors in the carton, or bare for buyers who source their own wheels or glides.
Can you do a welded tube and a casting from one order?
Yes. Many buyers mix a tube leg for their volume line and a casting for their premium line on the same PO, packed together.
Is the knock-down hub the same across tube and cast?
The screwless taper hub is the same idea throughout the range; the arm it joins to is what changes between a tube and a cast leg.
