It is a perfectly smooth surface all the way across. A one piece slate has no seams to affect the playing field. When they purchased the table (around 35 years ago), they were told that a one piece slate was far superior. If you ask an owner of a one piece slate furniture style pool table, they will likely give you a different reason. These Fusions don’t really move around the room, but the up and down motion of the legs necessitate the one piece slate. These Fusion Tables, like the coin operated ones, have a special frame that holds the slate snug.
If you ask an Aramith Fusion Pool Table owner, they’ll tell you they love having a 3/4 inch one piece slate because it allows their pool table to lower to dining height, then raise again to playing height with a single click. When the pool table is put back into position final leveling is dialed in by commercial grade leg levelers. The cabinet holding the slate wraps and hugs the slate, so that even when the table is tilted on it’s side (experience required), it remains locked into place. But, these commercial pool tables are constructed differently. Moving a pool table in one piece can really mess up the seams where the three pieces meet on a three-piece slate. These coin-ops have a 3/4 inch one piece slate for this reason.
If you ask a bar or pub owner, they’ll tell you that they often have to move their coin operated pool tables around for special events. It’s the age old question: What’s better a three piece slate pool table or a one piece slate? Well, that all depends on who you’re asking.
