Desk is made of MDF but you wouldn't tell as the desk block is pretty solid. The instructions were on the cardboard box (with the legs) but you probably wouldn’t need it. Issue I had was the lower screw was once you wanted to tighten the screws you could only do 45-degree angle turns with the allen key that came with the contents but luckily only needed to do this sparingly. The bottom of the legs has cylinder plastic covers that are flat and screw into the bottom of the legs but you can unscrew them and have them without but leaves the legs with large holes for bugs etc to make a home so I kept it on. Overall for the price and what I was looking for which was a computer desk in a small space this worked out very well for me.
