Expected better

I had done what I thought was a ton of research before buying this mattress. After just a year I started noticing depression from my 155-pound body weight. Even after rotating my mattress every month to every 6-weeks, the wear on the bed seems too extreme for what it promised to be. Now a few more years have gone by and my hip, shoulder, ​and back have nearly as much discomfort and ache as they did prior to purchasing the bed.
