This was our first foray into pillowtops coming out of a 17 yr-old Perfect Sleeper set. I loved the soft feel of the pillowtop in the store, and for the first week, it was as fine a sleep experience as I'd ever had. Unfortunately, the P/T showed body indentations of about 1" in the 2nd week (which I personally believe is excessive). Worse, I started having problems in my upper back, which I've never had before. I don't know if this was just an adjustment issue, a problem with a too-soft P/T, or something about the Simmons pocketed coil that my back doesn't like. In light of information I came across later that Simmons' pocketed coils are neither durable nor long lasting, we've made the decision to return the product in favor of S&F. Just for the record, while I think the higher end Latitudes/Exceptionale products are superior to the Beautyrest World Class line, I just can't see paying in excess of $2K for anything but S&F.
