These desks are very sturdy and flexible. The legs are adjustable height so you can set up comfortable computer workstations. The feet on the t-legs are also adjustable to level the desk especially important with the larger desk. File drawers can be purchased at IKEA or anywhere to slide in under them. Installation instructions and hardware are included. Desk 1 is a large corner desk ($100), Desk 2 is the one that took some abuse, so the finish is not perfect ($25), Desk 3 is dark brown and one round end is available (another may be available later) ($65)
