ABSTRACT:
A chair measurement device includes a base configured to stably engage a chair seat in a manner simulating a person sitting on the chair, and further includes an upright member pivotally mounted on the base for simulating the person leaning against the chair back. The upright member includes an upper section having an arcuately shaped rear surface, and an elastic member is extended between the upper section and the base for engaging the chair back to facilitate positioning the device on a chair. The upright member is lockable on the base to facilitate initial positioning of the measurement device on the chair, but is releasable and movable against the chair back to facilitate taking measurements. The base and the upright member include planar surfaces for supporting measurement taking tools, and further include slots for locating the tools in square and predetermined positions on the measurement device. A method using the measurement device includes placing the measuring device in a chair with the upright member in a locked position on the base, and adjusting the position of the measuring device on the seat until the upright member contacts the back. The method further includes releasing the upright member and moving the upright member to a rest position against the back. Measurements can then be taken in a manner simulating a person sitting in the chair.
