We bought these chair covers for the purpose of covid cleaning between public performances. They were easy to put on and remove from the chairs, but it does take a little bit of practice to put them on quickly. This cover worked well over chairs with four single legs. At one venue we were using them on chairs with two U shaped legs, and there was nothing to hook the bottom corners of the covers on - so they looked a bit messy, but they still worked for the cleaning purpose we had in mind. The chair covers are suitable for low heat in a dryer, which means that we can easily clean them and have them ready to go for the next day.
