I got some for my partner because his sheets kept coming off and putting it back on was often something I would do because it was a task that took a disproportionately high level of mental energy for him. Before I got them, he was like "it's fine", and handwaving off the faff of putting the sheet back on, because it was just something he was used to. Afterwards he was like "oh my God, what a quality of life improvement from something so small"
