Our 6-year old innerspring was waking us up with back pain each morning, and the mattress store owner informed me that "memory foam" mattresses now make up 80% of his sales. I used to write for Sealy at my old ad agency, and even I wasn't aware of how giant this shift to memory foam had recently become.
Apparently, after 70 years of making beds out of metal, we decided there might be a more comfortable option.
1 week into my new memory foam mattress, I'm convinced we were right. What's wrong with us? What else are we currently doing for no other reason than that's the way we've always done it? What's the next big thing we're going to look back at and wonder what we were possibly thinking over the last 30 years?*
