Purchase rubber shims from a local hardware, furniture or pool table store. Choose flat rubber shims if your laminate surface is completely level. If not, choose a shim with a slight angle to help level your table. Measure the surface area of the bottom of one of the legs to ensure you get the proper width. Install the shims beneath all four legs of your pool table.
Place a throw rug beneath your pool table on top of your laminate flooring. Select a rug that coordinates with the rest of your family room, recreation room or den. Choose a throw rug larger than the perimeter of the pool table, so the table won't slip off the rug. Purchase a throw rug that has an attached rubber matting on its backside, so it sticks to your laminate floor, or buy nonslip rubber strips and apply them to the backside of your throw rug.
Insert furniture felt pads beneath each of your pool table legs. Purchase furniture felt pads at your local furniture or hardware store. These pads have a felt surface, and their thickness resembles cork. Select felt pads that have a circular shape, so each pool table leg rests in the center of the pad with room to spare on all sides.
Install furniture caster cups beneath your pool table legs. A caster cup is a small round cup that wraps around the bottom of a chair or table leg. Some hardware stores carry caster cups, or you can special order them online. Choose rubber caster cups that grip your laminate flooring, avoiding plastic caster cups that will slide against your flooring. Measure the circumference of your pool table legs to ensure that the opening of the caster cup is sufficient for your table.
