Abstract
A telescoping gymnasium seating unit including a plurality of movable upright frames respectively sized and movable between a first position wherein the frames are nested one in the other when fully telescoped and a second position wherein the frames are unnested. Each of the frames has a seating member thereon with an upwardly facing horizontal planar-like seating surface. Each of the seating members on each of the frames is vertically offset from a seating member on a mutually adjacent frame in the second position of the frames. The seating members are vertically spaced one above the other when the frames are in the first position and have a vertical spacing therebetween. Low friction devices are secured to the seating members and extend downwardly therefrom and engage the next seating member located therebelow when the frames are in the first position to maintain the vertical spacing therebetween uniform when vertical loads are applied to the seating members when the frames are in the first position.
