Not worth the money

Torn on this review because my husband loves this mattress. He's been pain free since day 1. I, on the other hand, immediately developed a strange mid-back pain, side pain and lower back pain. I'm lightweight so it may be that I don't sink enough, but I also think my body needs the support of coils. The "Medium" is definitely more of a firm. I do enjoy the sinking feeling but I find that I don't sink enough and not in the right places. We are returning this mattress because after about 70 days, my back pain is getting worse. I know many people love Tempur-Pedics but I don't think a full memory foam mattress is for me. If you're built like me (narrow shoulders, wider hips, lightweight, narrow boned), I would think twice before buying this.
