What are the chairs and fitness balls used for in lovers' hotels?

Plus sexy love, such as a woman sitting in a chair, a woman putting a fitness ball under her waist, things that can't be done at home can be done in a couple's hotel. But by the way, I would like to remind you that most hotels have accommodation and rooms, and almost all couples hotels open rooms, but the current domestic cleaning standards are not up to standard, so don't go to couples hotels if you can't go, which is unsanitary.
