Why do the Large and X-Large beds say “single fold,” while the XS, Small, and Medium say “two fold?”

Why do the Large and X-Large beds say “single fold,” while the XS, Small, and Medium say “two fold?”

Per our 1-minute demo video, the X-Small, Small and Medium beds fold/unfold twice, creating four layers of padding when the bed is folded and zipped together.  This is what is meant by “two fold.”  Therefore these smaller beds quadruple in length/width when unzipped and unfolded into a blanket .

I originally made the Large and X-Large so they folded/unfolded twice just like the smaller sizes, but they were so humongous that they wouldn’t properly fit in a household washer/dryer.  So I made the LG and XL so it folded over ONCE, so there are two layers of cushion, and added more batting to the inside to provide adequate padding.  So the LG and XL actually double in size when you unfold them into a blanket.
