Quick delivery and all pieces were included. Very easy to put together... Just attach the keyboard tray. It adjusts smoothly up and down by a lever on the side. Love this item and was a good cost effective way to modify my existing desk rather than splurge for an entire adjustable desk.Definitely recommend!It's really sturdy and bigger than many other options. I keep my large screen on another stand but this holds my laptop and keyboard with plenty of space to spare.I bought this skeptically but actually it's really nice.Working from home has destroyed my back from sitting at a desk for so long. I wanted a cheap solution that wouldn’t require me to buy a completely new desk and this was it!! Very sturdy, super easy to assemble, and works as advertised!Also, as a plus, it provides more space than my normal desk because it’s 2-tiered!If you’re in the fence, buy it!! So worth it!I’m surprised at how easy to use this is! It’s a little difficult to pull up sometimes but that may be because of my two full monitors. It’s sturdy despite and im very happy!It was easy to assemble and it's perfect for what I wanted. It moves up and down easily and while it's bigger than I expected it to be, it holds a lot of stuff easily and still moves up and down effortlessly.I have worked in places that use these standing desks and wanted one at home. The ones at work were over $400. I went with a less expensive version and overall happy with the purchase. If I had to do it over again I probably would look for one with lift assist as lifting the desk can be difficult due to the weight.My husband has been having horrible low back pain from sitting so much as he is a full time college student sitting for sometimes 8+ hours a day. I decided to try a standing desk for him to give him the ability to stand while watching videos or reading and he LOVES it! He now stands more than he sits for school and his pain and flare ups have become a lot less frequent! Very good quality for the price as well. I did a lot of research on the cheaper group of standing desks and this one seemed to have the best reviews on the lower end of the price scale and it has been wonderful!Easy to carry, move and extremely easy to lift up to standing position!It was a bit big for my needs (my desk is small as you can see) and the keyboard holder pops out a lot so I removed that panel, but I decided to keep it anyway, as it looks good, is pretty sturdy, and is easy to lift up and down. Most of the structure is already mounted, all you need to do is to add the keyboard holder (which I didn’t for now). I don’t know how much I will be using the standing function as is, but I like the idea to find the perfect balance with your desk and chair to have you screen at eye-level and your arms at a natural angle, and not break your neck on a daily basis.I honestly have not sat down while working since this item arrived. It's the easiest thing to put together and the lift/lower action is really smooth. My only complaint is that while typing with the stand raised I noticed the monitor shaking quite a bit. Drinks will also show there is a lot of movement while typing. I believe this is not out of the ordinary for these types of stands, and probably the crappy monitor design makes it worse. I would still recommend this product.I was so excited to get a stand up desk as I have been working from home, when I opened the desk there was a crack running down the middle, and the desk top does not fit properly in the box which I assume is why this happened.. The company could not offer me a replacement and amazon requires a return of the item as large and unusable as it is. Extremely disappointed in this policy since it takes 14 days to get refunded in the meantime I will look into purchasing a different standing desk and have to wait for my money back.Although I had a hiccup with ordering the white version, the desk is actually pretty good and works well for a treadmill desk set up. It's super heavy so make sure you have a sturdy desk to set this up on.I wish the keyboard tray could slide in and out, but it's stuck in one setting.Amazon customer support helped me a lot in sorting out the issue I had with my initial order to kudos to the team!
