For mattress testing in general, we sleep on all mattresses for at least a week, if not longer (many of my picks I slept on for closer to a month) depending on how they perform. I previously tested all of my mattresses on an old Article bed frame, and now am testing mattresses on an IKEA Tonstad bed frame. For back pain, I pay attention to my back pain spots the night before and see if they're better or worse in the morning after a night on this mattress. I also look for pressure relief as a side sleeper (and another pain source) and I ask my back-sleeper husband about his experience and if it created any issues or pain for him that I wouldn't discover as a side sleeper.
