Versatile Arm Folding Mechanism Featuring Multiple Levels 3 6 8 And 10

In furniture, the armrest folding (stepping) mechanism is a functional feature that allows the armrests or headrests of armchairs, sofas, and recliners to be moved at different angles (usually in 9-degree increments) and fixed in the desired position. The numbers 3-6-8-10 indicate how many different steps (angles) this mechanism can move or be locked in.
