Love this ergonomically friendly varidesk. I had one at my job a few years ago and when I moved to a new job, missed out..I finally bought one on line for myself at home (after a few years of trying to jimmy-rig a standing desk arrangement using my text books etc). The VariDesk is worth every dime. It comes already assembled - super glad for that. It is sturdy and solid, yet easy to shift from sit down to stand up position (I'm a 46 year old woman and this was key for me - the ease and smoothness of being able to shift this up and down, with no heaviness or pressure on me). It smoothly shifts up and down, with no wobbling to my monitors, laptop and keyboard. I read some other reviews on Amazon where people complained that when they rested their arms or elbows on it, it buckled. Well that's just stupid. This isn't meant to rest a person's weight on it. It is meant to solely hold the weight of your tech equipment...basic monitors, laptops, keyboards, etc.... And it is smooth to operate, and saves my butt and back from sitting down all day. Love it. Great buy and worth every dime.
