UPERGO Vertical Laptop Stand Review
Color: Black Walnut, Color: Black Walnut
I was absolutely blown away by the solid construction and impressive heavy weight of the UPERGO Vertical Laptop Stand. This stand securely holds my iPad Pro 13-inch with Magic Keyboard in a perfectly snug position, and adjusting it is a breeze with the included tool for the four screws on the bottom. The balance and heft of the stand are just right, giving me complete confidence that it will hold laptops, iPads, or any other devices I want neatly tucked away.
Since purchasing this stand, I’ve found it fits perfectly beside my desk riser, tucking nicely out of the way and helping to organize my other devices. It has opened so much needed desk space and added a touch of order to my workspace. I highly recommend this stand to anyone looking to improve their organization—whether it’s on a nightstand, desk, table, or anywhere else you need a reliable and stylish solution.

Definitely pick one up!
Color: Black Walnut, Color: Black Walnut
This stand looks great, the material has a nice finish, and the quality is really good. It holds two MacBooks very comfortably. It doesn’t take up much space and has a good weight to it so it will not move easily. Great buy!

Finally a dual vertical stand with a stable build, quality materials, and snug fit for MacBook Pro
Color: Black Walnut, Color: Black Walnut
I don’t normally write reviews but I’ve had so much trouble finding an adequate vertical stand for two MacBook Pros that doesn’t worry me every time I look at it. I can finally say with confidence that I won’t need to replace this one. Not only is this stand attractive, it is simply a lot more sturdy than the all-metal “industrial” stand that it will replace because my MacBooks fit into it without wobbling, it has a wide surface area base, and its overall fairly heavy due to a solid wood + solid metal build.
This vertical stand stands apart in the two areas that my previous two stands have failed at:
1. A snug fit with a protective lining so that the laptops don’t wobble and bump into each other (the dual Omoton I have suffers from this terribly where the laptops bump and lean against one another)
2. A solid base with enough weight to prevent the stand from tipping over from an accidental bump (my single-laptop human centric mount is beautiful, but the base is too light and narrow so that any decent contact feels that it might tip over)
This stand has a very solid build quality with a nice weight to it which is comforting when potentially storing two expensive pieces of hardware in a vertical orientation that lends to tipping over (MacBook Pros are absurdly well over $2k a piece now on average). This is now the third vertical stand I’ve purchased for my two MacBook pros (work & personal). It’s not my third because I compulsively purchase things I don’t need (though I do do that), but rather because the previous two models felt unstable and carried a greater risk of damaging a few thousand dollars in equipment.
Anyway, this is my first purchase from this brand but I highly recommend!

Perfect!
Color: Black Walnut, Color: Black Walnut
Amazing! I work off two laptops and this keeps them organized and aesthetically pleasing. True to color. Super sturdy. Doesn’t slide around. Shown in pic on far right.
