MI-7971 is the perfect solution if you're looking for a multi-use stand that works as a mobile laptop cart, podium, and lectern. This portable, rolling stand up desk can be easily raised from 40.5" to 48.75" with a quick turn of the twist knobs. The 48.75" max height of this stand is taller than most podiums in the market, which is a great feature that accommodates more user heights. The durable casters allow you to roll the stand to a new location and simply step to lock each of the 4 wheels for a stationary position.
