These are plans to make Fisher's adjustable desk. This is a light-duty desk that has a surface height from 27 1/2" in its lowest setting. The desk can be raised all the way up to 44 1/2" high to be a stand-up desk. Additionally, the surface can be tilted up to be a drafting table or even further to become an easel. There's a small surface catch piece that can be removed, flipped, and re-secured to keep your work from sliding off the tilted surface. There's a total of eight different height configurations and three surface angles at each one giving you plenty of adjustability with this little desk!
