Oh my goodness! Sounds like you have a very active, healthy python! I agree that she's probably just fine, and don't be surprised if she remembers that hole in your chair and tries to go for it every time you sit there. My daughter's BP managed to get herself into my husband's brand new speaker through a hole I never saw. She refused to come out and I had to put the whole speaker into a tote until she came out at night. She remembered that speaker and the next time I sat near it she went right towards it!
My ratsnake loves to hang out in my bathrobe, and will look for sleeves and necklines to go down if other people are holding her. :-)
Anyway I'm sure your snake is fine. If she gets caught in or around things thing in the future, I find that tapping their tails is annoying and they'll move forward to escape that. If you can direct the head in the right direction while tapping the tail they will generally be able to be persuaded in that direction.
