What is a floating shelf and how is it supported?

• A. A shelf that rests on top of brackets only.
• B. A shelf attached to a wall with metal brackets.
• C. A floating shelf is supported at ends by dados or shelf pins; not flush with back; attaches to sides or a cleat.
• D. A fixed shelf glued to the cabinet.

Answer: (C)

The idea being tested is how a floating shelf gets support without visible brackets, so it appears to hover on the wall. A floating shelf relies on hidden, end-supported hardware rather than a visible bracket. It is supported at the ends by dados routed into the shelf ends or by shelf pins that engage a wall-mounted support, and it attaches to the sides or a cleat rather than simply resting on top of brackets or being glued to a cabinet. The back isn’t flush against the wall, which helps hide the hardware and maintain the floating look. This approach distinguishes it from shelves that rely on visible brackets or permanent adhesion.
