Abstract: There is provided a fan assembly comprising a motor-driven impeller arranged to generate an airflow, an air outlet arranged to emit the airflow, a plurality of sensors arranged to measure a value for each of a plurality of air quality characteristics, a display and a processor. The processor is configured to receive measured values for each of the plurality of air quality characteristics, identify one of a corresponding set of intervals within which the measured value falls and select an air quality index value associated with the identified interval. The processor is then configured to identify the highest of the selected air quality index values as a current overall air quality index value and to cause the display to display a time series plot of the current air quality index value and a number of preceding air quality index values.

Abstract: A furniture assembly kit including at least a first support structure, a plurality of furniture components, each component including a base structure having a component width dimension and a component length dimension, a sub-structure supported by the support structure and having a substantially flat support surface defined by a circumferential edge including first and second lateral edges, the sub-structure forming a lip member along at least portions of the first and second lateral edges, the lip member having a distal upper edge, the space adjacent the support surface and between the lip members being a furniture receiving space and wherein different subsets of the plurality of components can optionally be positioned with the base structures supported by the support surface and with the base structures of the component subsets substantially covering the sub-structure support surface, each different subset including at least two of the plurality of components where at least one of the furniture components i
