Round rugs

I saw these little, round, 100% woollen rugs, and thought the dark grey one was just what my son needs to go underneath a coffee table which he is worried might scratch the floor in his first flat (who would have guessed that he could be so house proud?)
He wasn't sure so I didn't buy it, but it was such a good price that I wish I had because I think I want one myself! Looks like I'll be driving back to La Rochelle again very soon!
