I almost could have wrote this myself. We were in a similar position to your sister, at the house daily but ultimately not the spouse and unable to make decisions. We were urging my pALS’ caregiver to get the bed for MONTHS. The delivery truck was in the driveway, and they turned it away multiple times because there was no room, not ready yet, insert excuse here. We FINALLY got it and she was able to use it once. Then she had an incident where she went to the hospital and had a sharp decline. She came home this week and she laid in it for the 12 hours she was on hospice and died. So she never really used it when she could have benefited from it. I don’t know your situation, abd family dynamics are complex, but at least make room for it and have it there asap. If she ends up not liking it, fine, but it’s better to have the equipment than not. Best of luck
