On its vented tabletop, this portable ergonomic adjustable laptop stand from Urbankings fits computers that are 12-17 inches wide and includes an attachable mouse pad tray. The completely adjustable laptop desk has auto-locking joints that click into place so it won't collapse on you, and it can be positioned in a variety of configurations to match your ergonomic work-from-anywhere demands.Each locking joint has a blue button that you press to unlock the joint, allowing you to position the leg at any angle you want; this blue button also has an arrow pointing to the angle at which the joint is positioned, allowing you to set the opposing side's joint to the same angle without guesswork.It took me a few minutes to figure out how to move, lock, and level the joints at first (of course, I didn't read the directions), but once you figure out how to do that, it's simple to modify as needed.This adjustable laptop stand can be used to support your laptop when you are sitting in bed or if you wish to work in a standing posture when you are weary of sitting. You will adore being able to operate on your laptop while lying in bed, and you will not miss hunching over the keyboard and suffering from severe shoulder and neck ache.For more visit:httpsurbankings.store/abs-plastic-360-rotating-with-10-angle-adjustable-laptop-stand-riser-a25
