How to play:
Apart from the players being seated, the other major differences are a smaller court, lower net and players must always keep contact with floor at all times except when making a defensive play in the back or front zones. The court is divided into two sides of five metres deep by six metres wide. The net height, lower than that of able-bodied or standing volleyball, is set at a height of 1.15 metres for men, and 1.05 metres for women.
Each match is a best-of-five sets. The first four sets go to 25 points while a fifth and deciding set goes to 15. In all sets, the margin of victory must be at least two points. There are a maximum of 12 players to a team.
