I own two full-sized Samaya cushions, and I absolutely love them. What I didn't love quite as much was toting them around for teacher trainings and frequent work travel. I was extremely excited to learn about this smaller-sized solution, read in the blog that it was used for international travel, and thrilled that it actually fits inside my carry-on bags (even in a compartment of a computer overnighter I picked up at an office supply store)! However, although the dimensions are exactly right for travel, there's something in the sitting experience that did not translate for me. I can't tell if its the height (its a little shorter) or the rectangular shape-or even if it'll just take some getting used to-but it's not quite as comfortable as the original. I will say this: the materials are fantastic (the same excellent quality as the original), and it's as good a temporary solution as I can possibly imagine!
