Took a gamble on this mattress with great reviews and it paid off! It really comes down to personal comfort. For reference, I had previously purchased a 7" medium firm gel memory form mattress, and it just wasn't fit for me. I am a back sleeper and the 7" gave me back pains every night. I have said goodbye to my back pains since the 1st night sleeping on this thicker, firm mattress. I have tested this mattress out for a month now, and am still super satisfied. It was worth every penny! Highly recommended!
