1. An adjustable desk frame comprising:
a first extendable table leg including a first outer housing, a first inner housing, and a first actuation mechanism to selectively extend and retract the first inner housing relative to the first outer housing;
a second extendable table leg including a second outer housing, a second inner housing, and a second actuation mechanism to selectively extend and retract the second inner housing relative to the second outer housing;
a first motor configured to drive the first actuation mechanism to selectively extend and retract the first inner housing relative to the first outer housing;
a first linkage coupling the first motor to the second actuation mechanism such that the first motor is configured to drive the second actuation mechanism in unison with the first actuation mechanism;
a third extendable table leg including a third outer housing, a third inner housing, and a third actuation mechanism to selectively extend and retract the third inner housing relative to the third outer housing;
a fourth extendable table leg including a fourth outer housing, a fourth inner housing, and a fourth actuation mechanism to selectively extend and retract the fourth inner housing relative to the fourth outer housing;
a second motor configured to drive the third actuation mechanism to selectively extend and retract the third inner housing relative to the third outer housing;
a second linkage coupling the second motor to the fourth actuation mechanism such that the second motor is configured to drive the fourth actuation mechanism in unison with the third actuation mechanism
a first crossbar coupling the first outer housing of the first extendable table leg to the second outer housing of the second extendable table leg;
a second crossbar coupling the third outer housing of the third extendable table leg to the fourth outer housing of the fourth extendable table leg;
a third crossbar coupling the first outer housing of the first extendable table leg to the fourth outer housing of the fourth extendable table leg; and
a fourth crossbar coupling the second outer housing of the second extendable table leg to the third outer housing of the third extendable table leg,
wherein the first crossbar, the second crossbar, the third crossbar, and the fourth crossbar each include multiple segments that facilitate adjustable spacing between the first extendable table leg, the second extendable table leg, the third extendable table leg, and the fourth extendable table leg.
