Abstract: A desk lift mechanism includes: a base mounting bracket configured for mounting to a desk; a plurality of parallel arms pivotably coupled to the base mounting bracket; a desktop mounting bracket pivotably coupled to distal ends of the parallel arms; a spring connected between a proximal end of one of the parallel arms and the base mounting bracket; and a strut connected between the proximal end of the one of the parallel arms and the base mounting bracket. The strut being configured to restrain movement of the parallel arms in a downward direction.

Abstract: An adjustable armrest assembly including a base configured to be mounted on a side of seat, an armrest, and an adjustment assembly configured to adjustably couple the armrest to the base. The adjustment assembly includes first and second rows of grooves, an adjustment slot located between the first and second rows of grooves, a clip stopper configured to selectively engage the first and second rows of grooves, and a threaded stud coupling the clip stopper to the armrest. When the armrest is rotated in a first direction, teeth of the clip stopper disengage a first pair of grooves and permit the armrest to slide relative to the adjustment slot to adjust the armrest into a desired position. When the armrest is rotated in a second direction, the teeth of the clip stopper engage a second pair of grooves to set the armrest in the desired position.
