In short, I love this desk. I spend a lot of time in front of the computer for work. I decided recently that sitting in front of the computer for 8-12 hours was not good for my health and my butt was getting sore. I looked at stand-up desk options. There are desks available that look like a normal square desk and has a motor for lifting the high of the desk platform. However, they're usually pretty expensive and would replace your existing desk. Then I ran across this Varidesk option. I was a little skeptical if this would work and be stable enough. After reading other reviews of people loving it, I bit the bullet and spent the $400. A bit expensive I thought but hey, for your health, that's cheap overall and cheaper than the full desk option. I received the Varidesk about 4 days after ordering. I thought the UPS guy was going to break his back carrying it to the front door. The package weights about 70 lbs. As noted, the installation is pretty straightforward. Getting it out of the box is the most difficult task. It comes packaged in a very sturdy cardboard package. Once you pull out of the box, remove the plastic wrap, you literarily sit on top of your desk. Put your stuff back on the desk. Done!! Ok, you do need to route your keyboard and mouse wires through the back of desk so it doesn't pinch the wires when lowing the desk. It's easy to route them this way (tip: route them straight back in the middle and over the top horizontal metal support under the monitors platform, use some plastic wire hangers that can stick to a surface, stick to under side of monitor platform ). I found putting the cables in the down the middle of the desk, rather than on the sides where the hinges are located, eliminated the possibility of pinching the wires when lowing the desk all the way down. This desk is very sturdy and has no problem with twin 23" monitors. When raised/extend the Varidesk all the way to the top, it's still sturdy. Now if you happen to hit or knock into it when raised, the monitors will shake but no enough to worry about them falling off or Varidesk falling over. NOTE: If you have a 15+ lb cat, you might want to lower the desk at night. They haven't jumped on it yet but I'm thinking if they do when the desk is fully extended, it could knock something off. However, I think its sturdy enough that I don't think the Varidesk would fall off the desk. I've had this desk for about 2 weeks. I love standing up now when I work now. I find my self moving around a lot with my feet, while stretching, bending, squatting, and even breaking out in dance when a good song comes on. One other thing I really like about standing is you can easily position yourself in front of the monitor you're viewing. Instead of just turning your head side to side, you move your entire body in front of the monitor you're looking. The ergonomics of this desk at great also, The curved cutout in front of the keyboard along with the mouse platforms next to it make it comfortable to lean and support yourself as you're moving your body back and forth between monitors. The monitor platforms for the monitor are the perfect height for me. HOWEVER, I will note, as other reviews have, the desk would not be ideal for taller people without having your entire desk elevated. The Varidesk needs a stable platform to sit so I would caution setting it on something that's not rock solid to prop it up. I'm 5' 9" and it's the perfect height for me for both standing and sitting. My desk is 28" tall. The Varidesk is very easy to raise and lower (see video on Varidesk website). The spring loading is enough that a smaller, weaker person could still raise/lower the platform. My only complaint (just so I have at least one) is you might feel you lose some flat surface real estate on your current desk. However, I quickly figured out how to rearrange my desk items to fit the new setup. I actually like it better than my previous setup now. The new setup is much more ergonomic and comfortable than my previous setup. I can standup working an entire 8 hour day and still feel great. NOTE: An anti-fatique mat is essential to stand on so make sure you order one along with the Varidesk. You'll want it the very first day you use it. I bought the Genuine Joe mat. It has worked OK but I just ordered the CumulusPro because I want more cushion on my feet. I'll review when I receive it. I highly recommend this desk to anyone that keeps their butt in their chairs too long and doesn't want to spend the money or have the room for a full sized motorized lifting desk.
