The connecting shafts (dowels) with the chair base are made of high-quality steel, while the casters are made of reinforced polypropylene with a polyurethane surface. Polypropylene is particularly resistant to weight and water, and it has high resistance to temperatures up to 125 degrees Celsius. Additionally, its durability is not limited to weight, water, and temperature but is unusually resistant to many chemical solvents, acids, and bases.

• Pin dimensions: diameter 1.1 cm x height 2 cm.
• Total thickness at the wheels: 5 cm.

These casters provide smooth and quiet rolling without annoying squeaks, thanks to their sturdy construction and the appropriate materials used. The soft polyurethane surrounding the wheel makes it ideal for any type of surface without damaging it. Rolling is smooth whether your chair is on a wooden floor, tile, carpet, or anywhere else.

The product does not require any special maintenance except for cleaning the casters and removing any hair that may have accumulated on the rolling axles.

Replacing the casters is easy without tools. Pull the old casters from the chair base and remove them. Then, insert the new replacement casters by pushing the pin into the socket until it locks.
