I just made one for my sister who is in a nursing home and in a wheel chair. I think I mad it about 45 or 50" wide because I wanted it to come around their sides (no draft). I used warm & natural and backed it with flannel. The reason is that she is always cold even in our hot, hot summers she wears a light jacket or sweater. I would make a variety because the nursing home will know who is hot and cold. Our sewing group also did some quilts, we made them 45" wide by 55".
