I received this mattress for free from influenster in exchange for my honest review. This mattress is a game changer! I received the extra firm to try out, and I was actually kinda nervous at first that it would be too firm. The first night was indeed an adjustment but by the second night I realized how important it is to invest in a good mattress, I had dealt with insomnia for quite a while in my life and I honestly believe now that my old mattresses were at least 80% of the problem. I don't toss and turn anymore. My neck doesn't hurt in the morning. And instead of having anxiety around bedtime, I actually look forward to going to bed. I literally feel like a goddess ready to take on the world by morning time! I love my beautyrest black and I will be recommending to anyone who will listen!
