We purchased a new adjustable bed about a month ago and we fight with the sheets every night and they come off. These sheet grippers are the perfect solution. They are very well made. I was surprised how easy they were to put on. I was able to put them on by myself and I could take them off by myself when I was ready for them to come off. We have not had the sheets slips one time since we put these on. I definitely recommend these as a must purchase if you have adjustable beds especially.
