1. A height adjustable desk comprising:
- a work surface;
a first leg assembly attached to the work surface;
a second leg assembly attached to the work surface;
each of the first and second leg assemblies including a lift mechanism, the lift mechanism including;
a first member;
a second member moveable relative to the first member along a longitudinal axis;
a third member moveable relative to the second member along the longitudinal axis;
a synchronization assembly coupled to at least one of the first and second leg assemblies, wherein the synchronization assembly is configured to balance movement between the first and second members with movement between the second and third members; and
a counterbalance mechanism assembly configured to counteract a force exerted on the first and second leg assemblies and attached to a bottom surface of the work surface.

Abstract
A height adjustable desk can include a work surface; and at least one leg assembly connected to the work surface. The at least one leg assembly can include: a first member; and a second member moveable relative to the first member along a longitudinal axis; and a counterbalance mechanism connected to the desk and configured to counteract a force exerted on the work surface. The counterbalance mechanism can include: a wheel; a gas spring having a cylinder and a moveable piston; a wheel moveably connected to the gas spring; and the tension member is connected to the leg assembly.
