Very High Quality Memory Gel Foam
Size: Mouse, Pattern Name: Mouse
Firmness is pretty solid, this material is high quality. This isn't that kind of foam that will start loosing it's shape after a year or two, this is a firm gel like substance and it's pretty comfortable.
The color is black as I expected, it's shape is rectangle just like in the pictures, it's appearance is as described.
The only think is that they do use a polyester cover, which does appear as though it may wrinkle over time, and it will likely not outlast the Gel Foam inside. Like I said though the Gel Foam is legit Gel Foam, I have heard these claims before only to find out that it's something far cheaper, that's not this.

Awesome
Size: Full Size, Pattern Name: Keyboard, Size: Full Size, Pattern Name: Keyboard
If you spend more than a few hours a day at your keyboard, stop what you’re doing and buy this wrist rest immediately. I was starting to feel serious strain after long typing sessions, and this simple accessory has completely eliminated the discomfort. It’s a true game changer for desk ergonomics.
The material quality is phenomenal. The memory foam (or gel) is perfectly supportive—it’s soft enough to cushion my wrists but firm enough that it doesn't flatten out or lose its shape, even after weeks of heavy use. The non-slip base is also fantastic, keeping it anchored exactly where I need it, no matter how intense my typing or gaming gets.
What I appreciate most is the immediate relief. The height and angle are spot on, positioning my hands and wrists in a neutral, comfortable alignment. The reduction in pressure on my carpal tunnel area was noticeable within minutes. I can now work for extended periods without the usual aches or stiffness.
This is a simple, high-impact product that vastly improves quality of life at the computer. It’s durable, comfortable, and absolutely essential for wrist health. Worth every penny for the long-term comfort it provides!

Pair with HyperX Keyboard Rest to complete the look!
Size: Mouse, Pattern Name: Mouse
Soft, comfortable, doesn't slide around, even on my XL mouse pad. Cool to touch which is nice.
After a year of use, fabric on top becomes slightly loose and bunches up when moving wrist around.

Well worth it
Size: Full Size, Pattern Name: Keyboard
Very comfortable and robust. This definitely looks and feels like a premium item. I had bought a few alternatives that were cheaper and they fell apart quickly. This one seems to have pretty resilient stitching and the fabric doesn’t bunch up which could cause a tear. The base has a non slip texture so it’s not going anywhere without some force. The cooling feel is a nice touch too.

Extremely Comfortable Wrist Rest
Size: Compact, Pattern Name: Keyboard, Size: Compact, Pattern Name: Keyboard
Hands down the best keyboard wrist rest! Fits perfectly with my HyperX Origins keyboard, almost like these products were made for each other! I really like the minimalist design of it and the quality does not suffer because of this. The memory foam is more comfortable than the memory foam on my bed, and the cooling gel stays cool no matter how long I'm using it. I have mine on a desk mat and it doesn't slip at all, it stays exactly where I need it which is great! Whether you're someone uses a computer for work all day or just a casual gamer, I highly recommend getting this wrist rest. It will change your life!
