Ergonomic Armrest for Desk and Chair

The BFKK armrest clamps to a desk edge up to 4.8 cm thick and to a chair armrest up to 7 cm wide and 6 cm thick, with a perimeter limit of 22 cm. It supports the forearm to reduce strain on the neck, shoulder and wrist during long computer sessions at home or in the office.

Clamp-On Installation Without Tools

The extender uses a clamp design that requires no drilling or permanent assembly. It can be fitted or removed in seconds and is light enough to carry in a briefcase or laptop bag for use across different workstations.

Fixed Dimensional Limits

The product only fits desks thinner than 4.8 cm and chair armrests within the stated width, thickness and perimeter boundaries. Buyers with thicker desks, wider armrests or non-standard profiles will not be able to mount it securely.

Questions about this item

How do I confirm the clamp is gripping my 4.8 cm desktop securely after installation?

The clamp fits desktops up to 4.8 cm thick with no edge bumps; once tightened it should sit flush and not shift when you lean your forearm on the pad.

What comes in the package and do I need any tools or extra parts?

The armrest extender ships fully assembled with its integrated clamp and mouse-pad surface; no screws, tools or separate purchases are required.

Which version should I choose if my chair armrest is 7 cm wide and 6 cm thick?

This single model supports chair armrests up to 7 cm wide, 6 cm thick and a 22 cm perimeter, so it matches those dimensions directly.
