I can't stay standing, though—not with Princess Celestia already seated. She ran through a quick list of options in her head and rejected them all, before deciding simplicity was best. She stuck a hoof on the chair to hold it stationary, took a moment to compose herself, and pushed upward, while using a tiny bit of telekinesis to keep the hem of her dress out from underhoof. Her plate wavered briefly in her field, but she got her hind legs on the chair without slipping off or dropping anything.
