My $85 sleeping pad gave out on night two of a 5 day trip

Tbh I thought I was being smart buying a budget inflatable pad from an off brand. It felt fine in my living room for a week but on granite tent sites near Moab it started losing air around 2am both nights. By the third night I woke up on the cold ground with my hip digging into the dirt. I ended up folding my puffer jacket under my side and that helped a little but not enough. The valve looked sealed and I couldnt find any holes but it just wouldnt hold pressure after the temperature dropped. Now Im looking at spending closer to $160 on a pad with better reviews but Im honestly scared to trust any inflatable again. Has anyone had luck with self inflating foam pads instead for rocky terrain?
