For my standing desk I have tried a thin flat foam mat, a thick flat foam mat, and wobble board (round circle with hemisphere on the bottom) and lastly the FEZIBO mat.
The FEZIBO's varied "terrain" somehow makes my feet hungry for movement and I find myself doing something new with my feet (and body) every few seconds. The only downside to this is that sometimes I get so distracted moving about on the mat that I stop whatever else I'm supposed to be doing because it's so much fun lol.
And if you just need to stand on the mat, its density seems perfect; it rescued my knees from my company's hard laminate-on-cement floors.
I'm 5' 10' and 180 pounds and this mat shows no signs that it will not support me for a long time to come
I think this is a good seller and show it to everyone.
