Looks good to me, someone else might know more about it. As long as it's safe I think it would be far better than tile. Tile is just so hard, like walking on a cement floor all day.
Yeah I can see how that might cause durability issues. It's designed to be used as flooring though so I wonder how long it takes for it to start breaking down. At that price it might be worth some testing. If it comes apart in small bits/crumbs then it could become dangerous if ingested.
