Meet the UpStanding Desk: a portable desk that turns any table into a standing desk, so you can work while standing. The desk is designed to be placed on top of any existing table. It has two levels: one for your laptop and the other for your screen. Each level is adjustable in 1″ increments. These desks are made up of 5 pieces of plywood and can be assembled quickly.
The UpStanding Desk has shelves with slots for cable management. The desk is available in Standard, Standard Tall, Double Wide, and Double-Wide Tall versions. This awesome product is on Kickstarter.
