A modular furniture unit can be configured to provide power distribution in conjunction with other furniture features. Embodiments of furniture arrangements may utilize one or more modular furniture units to provide one or more of such features (e.g. storage, seating, privacy, work surface, lighting, etc.). In some embodiments, the modular furniture unit includes an elongated upper member having an upper slot that has a first end and a second end opposite its first end. At least one leg is attached to the first end and at least one leg is attached to the second end. The elongated upper member may have a channel through which power cabling passes and outlets that are connected to such cabling. Different elements can be connected to the upper member via the upper slot or a downward facing opening of the upper member and/or to the legs to provide different furniture arrangements.

A shelf system for mounting a shelf to a wall, which includes a shelf having a rear edge and first and second shelf fasteners coupled to the shelf and protruding from the rear edge. The shelf system may also include a mounting bracket assembly for mounting directly to a wall and to which the shelf is to be coupled. The mounting bracket assembly may include first and second shelf engaging portions that have mounting apertures therethrough. Wall fasteners may extend through the mounting apertures of the first and second shelf engaging portions to mount the mounting bracket assembly to the wall. The portions of the first and second shelf fasteners which protrude from the rear edge of the shelf may be inserted into the mounting apertures of the first and second shelf engaging portions of the mounting bracket assembly to couple the shelf to the mounting bracket assembly.

A height adjustment arrangement (10) for an item such as a platform (12). The arrangement (10) includes a hollow first member (14) with an external thread (18) which is engageable with a thread on the platform (12) to permit relative height adjustment, and an elongate second member (18) which is engageable with a thread in the interior of the first member (14) to also permit relative height adjustment.

A product display shelf, system and method are disclosed. The product display system includes a shelf unit having a back shelf portion and a front shelf portion. The back shelf portion includes a first connecting element for releasably attaching the back shelf portion to an electrically powered support member, and the front shelf portion includes a second connecting element for releasably attaching the front shelf portion to the back shelf portion. The front shelf portion can also include a body portion and a display panel connected to or integral with the body portion, suitable for displaying information to a user.

A flexible shelving unit includes a support frame having at least one vertical guide rack, the guide rack including an elongated slot. The shelf unit is supported by the guide rack. The shelf unit includes a shelf plate framed by a front reinforcement portion and by at least one side reinforcement portion. The shelf unit when in a release position is moved to selected upward and downward locations by vertical displacement of at least one locating pin connected to and extending from the at least one side reinforcement portion which is positioned and sliding within the elongated slot. A flat end face of the at least one side reinforcement portion directly contacts a plate face of the at least one vertical guide rack with the at least one side reinforcement portion and the shelf plate in a horizontal position to frictionally retain the shelf unit in the horizontal position.

A shelf guard comprises a guard pivotable about a pivot point and a support configured to secure the guard to a shelf. The guard rotates between a first and a second position. In the first position, the guard allows access to the shelf and is balanced in a stationary position. In the second position, the guard prevents items from falling off the shelf. The guard's pivot point can be offset from the back of the shelf. The guard can rotate through an arc of more than 90° between the first and second positions.

An improved sleeve for a shelving unit having an annular collar wedge the sleeve against a post, wherein the sleeve has one of a retaining wall encircling the bottom of the sleeve or a retaining latch extending from a bottom of the sleeve, both to position and retain the collar during assembly and to support the collar during use.
