"As a longtime standing desk user, I can attest to the importance of having a good floor mat. I've used several, and this CumulusPRO is my favorite by far.
I've found a floor mat to be essential for standing desks. While my leg muscles have long ago adjusted to standing for long periods, I find the bottom of my feet are sore on a regular basis. Since I started using this mat, the soreness has almost completely gone away.
STYLE
Simple and attractive. The rounded corners and long bevel means you don't trip over it easily, and the fine pebbling texture keeps it from catching light and drawing attention. By my aesthetic standards, I couldn't ask for more.
OVERALL
It's pretty thick as these mats go, but that means it has a nice bounce to it. If you prefer a standing mat that is more spongy, where your feet sink in, Imprint also makes the Cumulus9, which I would recommend instead.
For my own feet, they've never felt better. Highly recommended."
