Swingers Club Gravitacja is in Wodzisław Śląski, in Silesia, and makes a point of sitting very close to the Czech border — it addresses visitors looking for a swingers club on either side of it.

Inside there are sofas the club cheerfully describes as built for company, open and closed rooms so guests can choose between sharing the experience and keeping it to two, and a dance hall with music and lights.

The club does not publish its street address, pointing visitors to Google Maps instead. Most events need no reservation; where one is required, book by telephone or SMS — the club notes that a call is much the fastest method on the day of an event, and that reservation confirmations are not sent automatically.
