Heavy duty tube steel frame with modular wire frame shelves and a wood desktop. keyboard tray rolls out for use and back under for space saving. Has swing out mouse platform and little pen (beer?) holder that clips on the pipes. Great desk, I'm just building an epic monster desk of doom from whence I will rule my spare bedroom with an iron, um, ergonomic keyboard and I don't need it anymore. Don't play with me on the price, it's firm. I'll just say mean things to you and block you.
