My husband and I had been looking at mattresses on a few sites over the last 4 months to fit both our needs. Our last 900 mattress was purchased about a year ago but my husband was having back pains and achy. After many reviews, I ordered this one and we setup it up --- I was concerned with the amount of firmness he wanted and the possibility of it not being comfortable for me. Four days in and we have both slept immaculately!!! Im stoked with this purchase
