We love this desk. It's so easy to change the height. Just push the up or down arrows on the controller mounted conveniently below the right corner and it automatically adjusts to a comfortable sitting or standing height. The top is very large and great for laying out blueprints, drawings or pretty much anything that you might need on a computer desk with room to spare. The frame is made of a heavy gage steel with adjustable leveling feet incase the floor isn't quite level. The top has an Ergonomic Curve which allows the user to stand closer to the desk. Top is made of wood and laminated with a choice of 3 different colors black,white or walnut. We have the black top which is very stylish but it does show dust and other bits of foreign objects like paper clipping. The direction booklet is excellent which makes assembly fairly easy. Fully assembled it's about 100 Lbs. so you will probably need help, at least when it comes to turning it upright. The tools and hardware needed for assembly are included in the box. The controller is screwed under the top. There are no starter holes for these screws. I had to make two small starter holes with a yankee drill. Being careful not to go to deep and through to the other side.
