The company worked through problems with me and it took longer than I would have thought to tweak the bed to my comfort but it had reduced the back pain I was getting from my old bed significantly. Would have liked the company to have not advertised items it did not currently offer when purchased but they have fixed some of those issues with the sleep data and made changes to their website to reflect this. Great bed, expensive but worth the comfort. Props to Sarah and Nate for all their help.
