I have side-by-side articulated twin XL beds that are 'linked' together to make one luxurious King bed for my husband and me. Getting XL Twins in a higher thread count that will 'fit' the beds when they are raised and lowered into the reading position has proved to be a challenge. In the past, I have resorted to ordering sheet sets from collegiate sales organizations that cater to the XL Twin crowd....but have constantly been disappointed with the fit and feel of those sheets. These Tommy Hilfiger sheets fit our beds perfectly and are made from high quality material that should last a long time. Hurray, at last, a good night's sleep.
