honeycomb pattern tilted keyboard stand, which raises the keyboard well and really helps you type more freely. Adaptable to many different types of keyboards.
Very light and blocks the keyboard on both sides so it doesn't slide to the right or left while you type.
If you want even more adhesion (but I've been using it for a while and don't feel this need), just put a small strip of double-sided tape to keep it attached to the side supports.
Easily stackable for transport
