This desk riser made me famous
Good news travels fast, especially theough the office grapevine! Since I set this up in my office, coworkers who have never even spoken to me have stopped by my office to see my new desk riser. Everyone remarks on how beautiful the brown wood tone color is. I agree. It is striking. I chose it because it's a beautiful color, and will not show dust as much as a boring black one. I will mention, though, it is a textured surface, that mimics real wood, so is not a good writing surface. My coworker has a black one that looks smooth at first glance but, she pointed out to me that it is not really smooth either. It has really tiny "pimples". So, it's not really a complaint, just an observation. It weighs about 45 pounds and is in a long box that's rather awkward for one person to carry. It actually has a note on the box that it requires a 2-person lift, but I'm not the type to ask for help and nobody was offering their assistance, so I managed to get it from my car into the office by myself. The handles on each end of the box were a tremendous help with that! Our IT guys had offered to help with setup, but we had a huge internet outage that day so they were busy. Patience is not a virtue I possess, so I set it up myself. Since it basically was delivered fully assembled (hence the huge box), setup was a breeze. I am an out-of-shape middle-aged woman with shoulder issues so my coworkers were shocked that I was able to move it and set it up by myself. I am mechanically-inclined, but that wasnt really a necessity as the only thing I needed to do was insert the keyboard tray into the slot on the bottom of the main component. There is a clasp on each side to lock the tray in place, so it doesn't slide out unexpectedly but that step isn't even necessary in my opinion, which I see no situation where a keyboard tray sitting on a flat surface would slide out on its own. By the way, the keyboard tray is NOT retractable - as in, it doesn't slide in and out to quickly/temporarily use your desk as a writing surface. It is, however, easily removable so you can pull it out and stash it to the side if you need your desk surface for an extended period. Then easily insert it back into its slot when you need the keyboard again. So, it's either in or its out - no in-between. It is easy to adjust from sitting to standing height by squeezing the lever on the right side of the riser to activate the hydraulic lifts. It is a smooth, controlled movement - not jerky at all. I'm 5'6" tall and it goes higher than I need it to be. It can be adjusted to go all the way down, flush with the desk, so I can comfortably rest my wrists while typing in the seated position. I purchased the 40", which comfortably fits 2 monitors, with room for a small fan in between. Before ordering, my office's IT manager sent me links to 3 risers he recommended from Amazon. This was one of them. He recommended a 42" to fit the dual monitors, but I went rogue and ordered the 40" because I measured my desktop and found the 42" would extend slightly beyond the edge of my desktop. I thought that would be uncomfortable. My coworker has the 42" - it does hang over rather edge a bit, but she says that doesn't bother her at all. Now my IT guy is telling me I should have ordered the 42" because they are going to be adding a laptop dock to my set up within the next year so I might need the extra space. I thought about exchanging but #1- it seems like too much trouble to box it up after having already set it up with all my monitors and other accessories AND disposed of all the packing materials, and #2- the 42" doesn't come in the brown wood tone color. So, I'm keeping the 42" brown one. According to the product photos, a laptop can be set up on the keyboard tray, so there's that option. Or, I will bring the brown one home for personal use, and buy a second one of this item (but in the 42" version) for my office. Shipping was slow, but that was disclosed during the ordering process prior to checkout. Trust the date they give you, even if it seems like a ridiculously long time for delivery. It took about a month for mine to arrive, but it arrived well-packaged and free of damage. The huge outer box is sturdy, and has made a great "playpen" for my cats! ... show more

Very Happy
Color: Black Size: 28"
This riser was perfect for the small desk in my hallway. It was easy to assemble with the enclosed tool and a phillips screwdriver (8 screws total). It does require both hands to lift it up (one on the left guiding it up while pressing the lever with my right) due to the weight of my monitor but the hydraulic cylinder holds it sturdily in place without slipping, once I stop at my desired height. It also lowers slowly and doesn't crash down to my desk top when I engage the lever. I wasn't expecting the keyboard shelf to be fixed at the max depth dimension so I would recommend double checking that beforehand so it doesn't hang off your desk too far. ... show more

Great use of $100
Color: Black Size: 28"
This was exactly what I needed, and I wish I had purchased earlier. So much cheaper than buying a standing desk. I work standing up rarely - and only for short periods - so I don't need to adjust often. Given the relatively low price, I was worried that the converter would be flimsy, but the 28 inch one easily holds my monitor, and the keyboard tray holds the keyboard and mouse pad. So far, the converter is holding up well. The pieces are heavy - so I needed a 2nd person to assemble. ... show more

No regrets - wish I’d gotten one sooner
Color: Black Size: 40"
This looks really nice, was easy to assemble, and works well. I wish I’d known about this desk topper sooner. I agree with the comments regarding weight. I have two monitors, keyboard, and mouse. It supports them, but when lifting the topper, I worry about the weight. That’s the only reason I removed a star - but so far, so good. It looks and feels like a good quality sturdy topper. I guess only time will tell. ... show more

So happy with this purchase
Color: Black Size: 36"
This was easy to set up, fit better on my desk then more expensive brands and works well! It feels stable, isn’t too heavy (other brands have collapsed our desks at work), and the price was amazing!

Easy to put together, but came with scratch

Came in today. Very easy to put together. Pretty heavy duty and the exact dimensions I needed for my home setup, however, when I opened the package, there was a large scratch on the top where the monitors sit. Also I’m kinda disappointed that it doesn’t seem easy to lift but I’m hoping it’s just me and it’s easier tomorrow. I will say it does go down smoothly and very easy. Very disappointed about the scratch, but hopefully I can repair it. I don’t want to deal with the hassle of returning, I need it for work. Overall, seems like it’s going to work for my needs. ... show more

A great buy
Color: Black Size: 36"
I love this. Super easy to setup, just squeeze the handle and gently pull the desk up. This is exactly what I was looking for. It sits on top of desk. It is large, but that’s what I wanted. The height is adjustable which is nice.

Great Lifting Desk!

Big enough to two screen OR one base with two screens and keyboard. Sturdy, and strong; but very space efficient. Still have plenty of desk space to have room to work without feeling cluttered. It’s heavy duty, but not too terribly heavy itself. Great quality and came in great condition. No damages or marks. Assembly was pretty quick. Took all of 10 minutes. It works great when it’s raised, I’m 5’6” and I love the height. ... show more
