Next time you have a surgery that makes it hard to twist your body in a car seat or even lift your self to move in the seat take a "LARGE TRASH BAG"
Have your driver just fold the trash bag to cover the bottom of the seat your going to sit in and be a buddy and hold it in place until you get in the car seat sitting with your legs out then let go so you can move around.
Then when you turn your body to get your legs in the car and move into place that is comfortable for you the trash bag will let you slide your body around turning you into a Human Lazy Susan.
It even help you move around in the seat and get out of the vehicle easier with less pain or effort twisting your body. Everyone here that had back surgery understands what I mean by that pain anchor that will not let you lift your rear or twist easily.
Just remember if it's a hot day and you have a 3 hour trip your rear will get a little sweaty if the air conditioner in your car does not work but in my situation it was well worth being able to move more in the seat than I would have with out it.
I Nurse at a Hospital showed me this when I thought she was crazy and came running out yelling wait! wait! don't put him in the car yet with a big white trash bag waving in her hand. Picture it and you could imagine what went through my head that second!
This is free advice that works for me and you try it at your own risk this is for educational information only. So if you decide the trash bag is a human hand glider or go bob sledding with it or simple just pertest the idea before surgery in your car and do it wrong and slide your self on the ground even on surgery day it all on you I did not make you do it just said it works for me and might be worth your personal research to make your trip easier.
No I do not recommend any brand of trash bag any type should do.
Any stupidity or failed attempts are all on you Forrest! So go cry to the nearest mirror if you need to.
