it gets slipped under your leg to lift it. But I used either a rolled up towel or a belt to do the lifting. Just to make it easy on my leg muscles.

I see there were replies to your question about a leg lifter. It was very helpful for lifting my leg into bed because your muscles aren’t quite awake after surgery and the muscles are a little beat up. The long strap has a loop that goes around your foot and you use your hands to pull up your leg into bed. For about $9 I was glad I bought it and used it for 2-3 weeks.
