There are so many choices on this site that it took awhile to find some sheets that were specifically for split king adjustable beds. The reviews were often contradictory. We finally decided to order a set, but they didn't arrive in time to wash them before Thanksgiving and we moved the day after that. We'll try them at the next bed change. The price was good. Stores only carry twin XL sheets just before kids go to college, so none were in stores in late Nov. Our bed/mattress saleslady gave us the steer to Overstock, for which we are very grateful. We started with a leftover king top sheet and the fitted bottoms from 2 sets of twin sheets that I found on Amazon, all in white.
