Everyone transfers in and out of beds, cars and chairs in different ways, so just a few general guidelines:

Care. You're not at home, so more than ever you don't want to spend valuable time in bed waiting for a sore to heal. Be extra vigilant during transfers to not damage your skin!

Help. It's generally easy to find people to help you with lifts and transfers, but over enthusiasm may be the next problem. Choose who you want to lift you, explain clearly how you want it done and stay in control of the situation. It may mean being a bit assertive but better that than being upside-down in the dust with your chair on your head.

Patience. If you need help and no-one is there, be patient, it will arrive! If people don't understand what you want or need, explain it again, you'll probably have much more time than you think.
