I waited a few weeks after receiving the mattress to review. Although the mattress was firmer than I had expected, I prefer a firm mattress, so this is fine with us. The odor that is common to these memory foam type mattresses took a couple of days to dissipate. We have absolutely no complaints about the mattress. My back pain that I was waking up with in the morning previous to purchasing this mattress has much improved. I would definitely purchase this mattress again and I do recommend it for others.
