Hand side stitching and the Origins range?

Your post above isn't 100% clear on the benefits of Hand Side Stiching. My understanding is that if you have it, it prevents the bellying out (soft side of the bed), thus effectively making the complete bed surface usable. But can the same benefit be obtained from non hand side stitching?

Given the importance of being able to use the full bed surface and not fall off the side, it seems odd that your 1500 origins model doesn't have HSS - could it be added at extra cost?
