ABSTRACT:
A gliding mechanism for a chair or sofa includes a bottom frame having a pair of parallel sides, a pair of swing arms pivotally connected to the interior of the sides near each end thereof defines a parallelogram linkage. A tube connected to and extending beyond the bottom ends of one pair of swing arms pivotally supports a pair of bars at the bottom of a chair or sofa support frame, and a second tube rotatably connected to the other swing arms supports a linkage which also defines part of the chair support frame, whereby the swing arms and support frame glide in unison.
