1. A furniture system comprising:
a worktop subassembly including a worktop member and an elongated frame assembly, the frame assembly including a body extending from a first end to a second end of the frame assembly, the body having an upper surface and a lower surface and forming a cavity, the cavity extending along a length dimension between first and second portions of the cavity that are adjacent the first and second ends of the frame assembly, at least one wall of the body defining at least a first opening into the cavity, the worktop member supported by the frame assembly so that an upper surface of the worktop is above the upper surface of the body;
a first leg extending upward to an upper end that is coupled to the frame assembly proximate the first end so that the upper end of the first leg resides at a height below the upper surface of the frame assembly and the first leg extends vertically downward below the first portion of the cavity so as to be vertically aligned below the first portion of the cavity;
a second leg extending upward to an upper end that is coupled to the frame assembly proximate the second end so that the upper end of the second leg resides at a height below the upper surface of the frame assembly and the second leg extends vertically downward below the second portion of the cavity so as to be vertically aligned below the second portion of the cavity;
an elongated a power subassembly housing supported by the worktop subassembly so as to be immovable with respect to the worktop subassembly at a location outside the cavity and below the height of a lower surface of the worktop member, the subassembly housing having a length dimension, a width dimension and a depth dimension wherein the length dimension is substantially longer than the width dimension and the depth dimension, the subassembly housing extending along a trajectory such that the length dimension of the subassembly housing is substantially parallel to the length dimension of the body; and
at least a first power outlet supported by the power subassembly housing;
wherein at least a first power cable extends within the cavity along at least a portion of the length of the cavity and from within the cavity through the at least a first opening defined by the at least one wall of the body into the power subassembly housing, and is coupled to the at least a first power outlet within the housing.
