A few things you might like to know about this product...
It's definitely on the the larger side (I'm using mine in front of my sink) It's wonderful to stand on while you're shaving or doing anything else in front of the mirror.
Some reviewers complained about the pebbles not being close enough together (granted there are other pebble mats out there, but for this price you can't beat the value) it's great for someone who doesn't want to sink too much money into a bath mat.
The pebbles on my mat are actually black (nothing like the gray in the picture) but this adds to the uniqueness of the piece... anything made from natural material will have variations
The felt backing hasn't stained the white porcelain tile on my bathroom floor (something I wondered about when purchasing the mat)
The best way to keep this mat clean;
Use canned air (the kind you use to clean keypads) it gets any dust out of the grooves, and definitely give it a polish with a soft cloth (it helps to keep it's luster)
Hope this answers any questions you might be having about this item!!!
