It worked really well for me for an extended backpack trip. Aside from weighing almost nothing and packing in to a very small bag, I was astounded at how well I could sleep on it. I'm 6'5" and 170#s. But felt comfortable by adjusting my body position. Also it takes almost nothing to inflate it and when you are using your lungs at high altitude you won't hyperventilate and get sick. I'm a side- sleeper and was fine.
