Great computer stand
Color: Gray
These stands are great. We now have two of them. My wife suffers from Carple tunnel syndrome and these stands lesson the effects when typing. They are stable and hold the computer securely.

Weighty and well designed
Color: Gray
The Bestand Laptop Stand is a testament to quality and thoughtful design.
From an ergonomic perspective, this stand truly shines. It elevates my laptop screen to eye level, promoting better typing and viewing to reduce strain on my back and neck.
Another standout feature is the weighty and solid construction of this stand. It's crafted from a single piece of aluminum, which not only adds to the stand sturdiness but also gives it a sleek, modern look. The surface is spacious and accommodates laptops from 11 to 16 inches.
Both the weight of the stand and the silicone treads below and underneath the laptop, and on a metal lip in front, ensure that neither the stand nor the computer move around. The manufacturer claims a 66-pound load-bearing capacity for the stand, and I believe it. This thing is rugged.
The inclusion of a slot at the rear for cables to pass through is a small yet incredibly practical detail. It helps keep my workspace organized and tidy.
Three slots in the stand aid with heat dissipation and are yet another thoughtful design feature that cools my laptop during extended usage.
While the stand excels in many respect, one limitation is its lack of height adjustability. However, if height adjustability is important to you, you’ll find lots of other options for stands here on Amazon.
Bottom line: I like it. Chances are, you will too. The Bestand Laptop Stand is a nice blend of durability, functionality, ergonomic comfort, and attractiveness—all at a reasonable price.

Pleasantly Surprised
Color: Gray
Honestly, I was a little hesitant buying a laptop stand that didn't offer an adjustable angle, but for the price, I couldn't pass up checking this out. I'm very glad I did.
First, this stand came really well packaged. For a $37 stand, I wasn't expecting much, but box and packaging was impressive. After pulling the stand out of the box, my first impression was this was both weighty and well machined. The edges were smooth, there were no imperfections I could find and the space gray color was dead-on.
As far as functionality goes, this is a tremendous improvement form having my MacBook Air sitting directly on my desk; the angle is perfect for my use case, the wiring hole in the back is more than adequate and the whole setup just looks slick. If you're hesitant about buying a cheaper stand that doesn't offer an adjustable angle, don't worry about this one, it does the trick.

Upscale look
These valet trays have a really upscale look and feel. I originally thought they’d make a great Father’s Day gift, but after using them, I realized they’re perfect for everyday use by the front door for mail, keys, wallet, and other essentials.
They have a nice weight and perfect size to them and the felt bottom keeps surfaces protected from scratches.
The combination of acacia wood and metal gives them a modern, sophisticated style that works well in an office, bedroom, entryway, or nightstand area. They’re both practical and decorative, making it easy to keep things organized while still looking polished.
Nice quality product.

Missing screws, can’t contact seller
The trays are really nice, however one came with missing screws. I’ve tried to contact seller via phone number that Amazon provided however the number is disconnected. Great quality other than the missing screws.
