Hi Bollo, unfortunately ` yes` is the answer.....the factory used to make partials for literally half the price of a topper before, but they stopped that well over a year ago now ..... if you`re getting a relatively good fit, and the density /wave etc. is satisfactory from cutting a partial from a stock system, there`s no advantage in ordering Custom-made as the price is the same you`ll have to wait a lot longer for it to arrive ! Kind regards.
