It can be hard for those of us that love to play billiards, but live in a tiny space. You would literally have to make the pool table the only piece of furniture in a room, which would also make it your dining room table, catch-all for mail and coats, and occasionally the only place you can sit. This will make it very dirty very quickly, which will inhibit your game if it gets enough crud on it.
If you want to use your space to the best of it’s ability, and still be able to play pool, you may want to look into the Chevillotte’s Very(Tables). This space efficient piece of furniture will become your best friend, as long as you can cope with about a $20,250+ price tag. A crank mechanism brings the lowered inner section of the pool table to meet the outer rim so that it is flush with it. A network of metal wires underneath the table will catch the balls when they’re sunk, and all this engineering has the tabletop at only 4 inches thick. There are also removable plates that will make for an easy cleanup. If you’re already going to drop tan extraneous amount of money, you might as well spend an additional $4,500+ to get the motorized version so you don’t have to crank it.
