The waterbed fitted sheet is similar to the flat sheet except it has an extra triangular fabrics sewn at the four corners and both flat and fitted are sewn together by the footer so bed stays made. The extra triangular fabric sewn at the four corners in the fitted waterbed sheet are turned over the corners of the water mattress and that is how you dress your sheets on your bed. In addition, the fitted sheet is always made few inches larger than the water mattress so the extra fabric can cover the mattress sides when made. The Poles attachment feature is an additional feature that is used to keep the triangular fabric fully opened so fitted sheet doesn’t come off easily. If your sheets include the pole attachment feature, you can insert 12 inches long wooden or plastic pole that is 0.5 inch in thickness (any pole can be used as it’s NOT INCLUDED). That Pole when inserted will keep the triangular fabric fully opened under your water mattress and makes it harder for the fitted sheet to come off.

Note! Poles are NOT Included
I like the fabric and it fits my waterbed nicely. There are no poles included fyi. I thought they were but I didn't notice that on the description.
At this point I am quite satisfied with the product. It still must pass the test of time.
