We took these on a boating trip with friends. We had no room to pack or store foam-style noodles. These were perfect; we could inflate to have fun, deflate to store. You can inflate full if you just want to drape arms across, less full if you want to sit sling style. When using sling style, the bottom (compressed by YOUR bottom) flattens as air moves to the two ends to provide good flotation support. Before we bought enough of these for our little group, I did a test drive of this product versus another that had handles that I found elsewhere. The other product's handles were hard and got in the way, and its body was generally too big around to be comfortable. THESE were the absolute winner and they held up well throughout the trip despite repeated cycles of inflation and deflation. One tip: don't try to inflate as fully as possible; fill with only enough air to be comfortable for the position you assume: with arms draped forward across, with noodle curved around the back, while sitting sling or saddle style, etc.
