Very classy looking! Perfect height and length for TKL keyboards!
This wrist rest is the perfect height and length for my TKL keyboards! The wood is soft and smooth. It looks VERY classy compared to some of the wrist rests I've used in the past. The non-slip pads work great too.
The only thing I could find that was wrong is that the logo is upside down. It's not visible though because it's the edge that meets the keyboard so it's never seen. I find it endearing actually! Everything else is perfect, so I'd definitely recommend!

Classy look, but finish issue
This walnut wrist rest looks great on the desk—simple, solid, and much nicer than foam or gel options. It has a clean, polished style that pairs well with a keyboard, and the non-slip base keeps it from sliding around.
I wasn’t sure how I would like it compared to the soft cushy pad I used before, but it’s actually been pretty comfortable. The firmness gives steady support, and I haven’t found it too uncomfortable even after longer typing sessions.
The one drawback is a spot where the finish has worn or dissolved. It wasn’t there when I first got it, so I suspect the coating isn’t as durable as I’d hoped. It doesn’t affect how it feels in use, but it does stand out on an otherwise sharp-looking piece.
Overall, it’s a nice upgrade if you want a wooden wrist rest, just be aware the finish might not stay flawless over time.

Classy, Comfortable, and Built to Last!
I’ve never tried a wooden wrist rest before, but after going through a few padded ones (even some expensive name-brand versions) that eventually peeled or fell apart, I figured this was worth a shot. And I’m so glad I did!
This walnut wrist rest is smooth, beautifully made, and looks amazing on my desk. I have a whitewashed office setup, but this piece looks so good that I half-joked about wanting to change my desk to match it! It adds a very clean, grown-up aesthetic to the space.
One thing I really appreciated is that it comes in several sizes to suit different setups. I ordered the largest available, and while it’s just a couple inches shy of covering the full length of my keyboard, it still works perfectly. It has non-slip grips on the bottom that keep it in place, and even though it’s made of solid wood, it’s surprisingly comfortable and ergonomic to type with.
It’s also super low-maintenance—just wipe it clean with a damp cloth. For the $26–$29 price range, I think it’s a fantastic value and honestly better than some of the big-name options I’ve tried. This is a quality piece I expect to hold up for a long time, and I’m really happy with it!!

Check the height of your keyboard before ordering
This is a beautifully made, elegant looking wrist rest. The finish is satin perfectly smooth to the touch. As keyboards vary in height, be sure to measure he height of the front edge of yours before ordering—I didn’t (which is entirely my fault) and found that this wrist rest is just a wee bit too tall, which positioned my wrists a tad higher than I’m used to. Another factor you may want to consider are the ergonomics of solid wood versus other materials and your personal preferences (e.g., I tend to prefer cloth covered gel, because he cloth keeps my wrists from sticking and the gel is cushioning). My closing thought: this wrist rest is that it is by far the best looking of any wrist rest I’ve ever seen.

Simply outstanding.
Color: Walnut, Size: 42.5 Inch, Color: Walnut, Size: 42.5 Inch
For years I was against monitor risers and stands as a concept easily defeated by VESA mount on monitor arms, but I overlooked a secondary function that monitor risers have: Display and storage.
I have too many keyboards. Three that I regularly use. Now I can throw two of them in a drawer when not in use, or I can look at them and appreciate them all the time. I’m not a fan the usual keyboard displays either: awkward acrylic stepladders that they are. So had to figure out something else.
I also have a headphone amplifier that I like quite a bit but was just sitting out on the desktop.
So I looked at seemingly every monitor riser that exists on Amazon, and elsewhere and found that this Fenge product (Rodin on their website) fits the intersection of value, good build quality, and beautiful design aesthetic. Unlike the Hexcal shelf, which has great build quality and design, but costs $600+, for $109 (at time of purchase), you get a visually intriguing multilevel riser with aluminum hairpin feet, good sturdy materials, a beautiful (albeit synthetic) warm walnut finish (though available in four other finishes as well). Cleans easily with a dry or lightly damp rag. This isn’t your Mind Reader riser with all function but being an eye sore. It’s also pricey enough and has an interesting enough product to feel premium without being unreasonably priced for what you get.
Building it was a pleasure. Packed so well, and everything in order as far as parts go. Wasn’t missing any, assembled so easily, and even better to see in person than in pictures.
I have a 72” desk and had to rearrange some things to fit it, but well worth it. It serves the functions I need, but if you need more from it (like holding your devices), there’s another variant with phone, headphone and laptop stand built into this design. Also, if this isn’t visually interesting enough, there’s a third version with RGB and an acrylic lower shelf to create some illuminating pop on your workspace. As you can see, my workspace has no shortage of illumination as is, so I skipped that.
But I think it did well. It partially displays my keyboard collection, stores my headphone amp, can hold a pen or two as I study, and I don’t need it to do much more on the regular.
I know it won’t fit every desk aesthetic, but if you already have tech statement pieces on your desk, this may be the perfect complement.
