6 reviews for Stand Up Desk Store Large Clamp-On Retractable Adjustable Height Under Desk Keyboard Tray | for Desks Up to 1.5″ (Large, 33″ Wide)

    So, I’ve had this keyboard tray for probably close to 4 years now, and I have to say, I am pretty happy with it. It is spacious, the clamps are big enough to deal with my new desk’s metal skeleton thing (yes, I know you are not supposed to use it this way, but guess what, it works), and the height adjustment means that I can get the keyboard right where I want. It might indeed feel a little wobbly, but I can hardly feel that while typing. Overall, thumbs up for a very nice design.The reason however that I am leaving a review 4 years later… is because, like a lot of people that have this keyboard, I faced the problem of losing the screws that attach the tray to the bracket. Let’s just say the information I managed to fish out this page was confusing to say the least, so I ended up disassembling the tray, taking the little piece that the bracket attaches to, and go play Cinderella at the fastener aisle of a home improvement store. What I got, and it works, are M4-0.7 x 12 mm flat head Phillips machine screws – pan head will work as well. I cannot swear that the length is the correct one, but it works. Now that I know that they fit, I am tempted to order some Loctite too…

    I had a very sturdy table that provided excellent surface area and I decided to use it as a desk. Downside was that I was used to having a keyboard/mouse tray on my smaller desk. I chose this tray because the C-clamps would fit my 1.5″ thick table and the large tray would hold my keyboard and mouse. After delivery, I had the tray unboxed and assembled in less than 20 minutes. Today was the first full day of working with the tray – a long 13 hour day – and I have ZERO shoulder pain or arm tingling! I am very happy with this purchase. The clamps are super sturdy, durable metal, and fit the table securely, even with my glass table topper (clamps are padded). The tray itself is plastic and could break with enough force but I do not intend to hit it with a hammer or use it as a diving board. I think this will be durable enough for my normal work day. I would purchase this again.

    Bought this keyboard tray almost 5 years ago, but unfortunately one of the screws came loose and was lost. Messaged the seller looking for the type of screw and they sent me a pack of new ones! Great product, excellent customer service.

    I am a graduate student who, like all other students, went virtual in March of 2020. I’ve had classes, projects, and even (virtual) fieldwork in ergonomics, yet spent all day hunched over my 14 inch lap top. I finally caved in and bought some stuff. It has only been 2 days but I am so grateful for this keyboard tray! It came together very easily, and I clamped it onto my desk while in zoom class. It has a small ridge at the front which is extremely uncomfortable for your wrists/forearms, but perfect if you have a wrist wrest (as seen in the first photo) because it keeps it in place. It also has a ridge in the back to keep your keyboard and mouse from sliding off the end. I bought the 20 inch tray because I have limited space underneath my desk, and it was challenging to find a keyboard that still left enough room for the mouse. I could not seem to find any keyboards without the number pad on the right side that were not Bluetooth, overly expensive, or poorly designed. I ended buying a keyboard that is about 15 inches wide from best buy, and it leaves just enough room for the mouse. If you have room to buy the larger size tray, you will have a lot more options in terms of keyboards. I also like that the tray height is adjustable. On the highest adjustment, it leaves about 3 inches between the top of the tray and the bottom of my desk. When typing and mousing, my elbows are at a perfect 90 degree angle. I gave the sturdiness a rating of 4 because the tray sort of wobbles up and down when you move it, but it does not affect function in any way. Maybe just don’t rest your elbows on it. Overall, would buy again!

    Super sturdy, big enough for a full size keyboard and mouse, stays put while im typing and using the mouse, very easy to install.
