There is nothing more ugly and awkward around an office than the seldom used Bárány chair. The following is suggested as an inexpensive substitute: Two circular boards 3 feet (91.5 cm.) in diameter, fitted with four ball casters and held together by a center pin. Four holes in the upper board are deep enough to hold the legs of a straight-backed chair. The chair can be immediately removed after the test, and the turntable can be conveniently set aside by standing it on edge against the wall.
A turntable for the Bárány test. Two circular boards are seen, the top one revolving on the bottom one. Both are held together by a fixed center pin and thumb bolt. Four ball-bearing casters are placed between the boards.
