It is nicely springy without feeling overly squishy.

"This mat is great. Unlike cheaper mats I've had in the past, my feet never feel tired from standing on it, even after long periods of time. It is nicely springy without feeling overly squishy. I've been using this mat at a standing computer desk for many months now and it beats the pants off of whatever budget piece of crap mat I had before. Because I'm lazy, I sometimes sit on a tall chair which I place right on top of this mat, the impressions that the feet of the chair leave are gone in seconds and left no permanent marks after many months of use."
