One downside I’ve noticed is that the “side rails” are completely ineffective unless the pad is fully inflated. If you release some of the air to soften the pad, the rails will collapse with ease if you roll onto them. This isn’t true of my Ultra 7R. I had it right next to the NeoLoft for a side-by-side comparison and they held up solid, even when the pad was slightly deflated.
One upside is that the pad seems to be quite comfortable while fully inflated. I haven’t spent a night on it yet, which will be the true test. If the comfort holds while fully inflated, it will likely become my go-to pad.
One neutral point is that the length and width aren’t bigger than my 7R. They’re essentially identical in those regards. The difference is in the thickness.
