Some reviews say the keyboard tray doesn’t slide all the way under..mine does. I think they may have forgotten to push the plastic pieces up as directed. Mine easily slides fully under the desk. There is not a lot of room on the tray but both my keyboard and mouse fit on the tray. Not as sturdy as a wooden desk would be, but it seems sturdy enough.
