If you're fortunate enough to have a full size snooker table this is the best way to protect it.
Peradon Full-size heavy duty table cover
This dark green heavy duty PVC full size snooker table cover is superb for both home and club use.
It's made from very dense PVC which makes it reassuringly weighty (over 5kg) and is bound to last as long as the table itself.
For full-size (12' x 6') tables.
