I'm looking for some 3x3 (preferebly) or even 4x4 1" thick mats to set up at home in a spare bedroom. To be used to BJJ/Grappling. No live takedowns... I would use the puzzle mats for easy storage and set up. But I do NOT like the texture of the cheap puzzle mats from Harbour Freight/Home depot meant for garage use or similar. Anyone have decent puzzle mats they can recommed? Under $10 per mat is a plus!
