also, you CAN have a wbbb custom made to lay "LEFTY" in which i chose to lay.
this means your feet go to the left of center, head to the right. this helps those who prefer to sleep in the right sided position.
a great option to full length uq's is aa 2/3 or 3/4 length, where a pad is inserted under the legs and the torso/thighs are protected by the UQ. my model is perfect for the WBBB, as is the yeti, the stormcrow, jrb's convertible, etc.
