Two or more players can use this 11 ft by 1.6 ft mat at once, and the two putters adjust from 21.5" to 35.5" so adults and children can share the same set. Foam slopes shape the roll and add difficulty as skill improves, while boundary barriers stop balls running off onto the floor. Six balls and a carry bag come with it, and the whole thing rolls up to 5 lbs for storage or transport. Suits a hallway, office or backyard.
