The mattress came with one part of an edge support damaged, it never came into position.  It was quickly replaced by Wayfair.  While it is a bit firmer than the Comforpedic mattress we previously owned, it has a wonderfully cooler feeling than the previous one.  I tend to be a hot sleeper, so this is a real plus to me.  

We are hopefully adjusting to the firmer feel.

The mattress arrived in a small, but heavy box.  The first one had started to expand in the box, which was perhaps the reason for the damage.  The replacement came tightly wrapped and quickly expanded to size when opened.  There has been no odor at all from day one.

The photo is of the damaged one, but the second one arrived in excellent condition.  Unfortunately these things happen, but Wayfair responded quickly.
