Our original bed mattress was very hard, so  we tried out numerous other brands of mattresses. At first the other brands did what they were supposed to, but after a while they would lose their quality and as a result my back pain would come again. While searching for more brands and comparing one with another, I stumbled upon this one and found that the reviews were mostly positive. I received this mattress quickly and it has currently served me well, reducing my back pains once again. I hope this mattress can last a long time.
