If your at-home work station consists of a laptop, monitor, keyboard, and printer, the Mount-It! Mobile Standing Desk ($140) may pique your interest. This desk features four shelves, which in total are advertised to hold up to 132 lbs. The height of the top two shelves are reportedly optimised for ergonomic laptop/keyboard and monitor placement.
Great for sitting down or standing up, this workstation is height adjustable up to 17 inches with 11 locking intervals, and it can be wheeled (and secured into place) so you can work from wherever, whenever.
