I think your advice would work well. I've been buying whole beds from one manufacturer (brooklynbedding.com & dreamfoambedding.com) to find that "sweet" spot for me. I'm on my second bed and things are getting better but this is wasteful and expensive. Of note, our bodies change over time, so what is comfortable during the summer (lots of exercise) might be different during the winter months - also changes that occur as we age. I think preventing weak muscles from developing around the spine might be beneficial.
