As metalwork and design technologies improved, the concept of mounting a shelf invisibly to a wall became more feasible.
[6] A floating shelf can be supported on hidden rods or bars that have been attached to studs.
Named for their distinctive 'T' shape, t-brackets distribute the weight of the shelf and fit securely within drilled holes with the aid of an anchor to provide additional support.
[citation needed] A floating shelf's weight capacity depends primarily on the number of wall studs its brackets are attached to.
While stud attachment is crucial, other factors also play a role, including the installation method, the shelf's quality and design, and its desired length and depth.
