Silicone products silicone caps silicone rubber feet for chair

Silicone rubber feet for chair applications can use a cap form that covers the end of the leg. The inner profile should match the leg shape and the intended seating depth, while the outer base meets the floor. Custom size and color allow the part to follow the chair design.

Inspect the leg end before fitting. A sharp cut edge or damaged corner can mark the cap from inside, where the damage may be difficult to see later. The cap should reach its proper seat without being stretched across an oversized feature. Check the chair with all feet fitted so the contact faces support it evenly.

Choose the material around the floor and care conditions. Keep particles away from the base during cleaning, since trapped grit can affect the surfaces in contact. If a cap repeatedly works loose, inspect its inner fit and the leg geometry before replacing it. A similar-looking cap with a different seating depth can change the chair's support height.

Material options

Custom silicone or rubber formulation, with dimensions and color adapted to the mating component.

Hardness range

Silicone: 20–80 Shore A; rubber: 30–90 Shore A. Assess the grade against this fit requirement: Check the chair with all feet fitted so the contact faces support it evenly.

Custom profile & fit

The inner profile should match the leg shape and the intended seating depth, while the outer base meets the floor.

Assembly considerations

Inspect the leg end before fitting.

Design check
