Bests & Worsts Reviews from Amazon

I am actually very sad that I have to write this review: After owning this mattress for less than six months, I honestly have to say that I am very disappointed with it. I purchased a different mattress from Amazon a few years ago when my ex-husband and I were still together, and I had no issue with it. I read the reviews and they were good. Purchased the mattress and had no complaints. This time, that was not the case. This mattress is comfortable for about the first 30 minutes. After sleeping on it for any length of time, it KILLS my back. My middle back is tight every time I wake up in the morning, and I wake up multiple times most nights. My boyfriend and I both have difficulty with our backs hurting when we wake up after sleeping. We have changed pillows, sleeping positions: everything. Nothing has made it better. We are both in our 20s, and shouldn't have this issue, especially not daily. If you're looking for a mattress and have back pain/issues, I would steer clear of this one, for sure. As I said, I had high hopes based on the reviews I read, but this has definitely not lived up to my expectations, or those reviews.
