An adjustable desktop workspace is disclosed having a base having a lower platform, an upper platform, and two pivoting arms mounted between the two. Each pivoting arm has a front and rear bracket. A locking lever on each arm fixedly engages the platform in an upright position at a variety of levels above the lower platform. There are also two stabilizing bars to limit side-to-side relative movement, and a biasing spring between the front and rear brackets to aide moving the upper platform.
