So overall I’m happy with the mattress but it wasn’t the smoothest experience. The first mattress we received was very soft, too soft for me but my wife loved it. It had some lumpy, smelly thing going on in the corner. Told amazon and they rushed a replacement out at no cost. The replacement mattress is in perfect condition but it’s much more firm. Some digging shows that there were 3 firmness levels for this mattress from Zinus, soft ,medium and firm. My guess is amazon is selling them all as the same product. Other reviewers say it’s either very soft or very firm. All I can say for sure is the firmness changed a lot between the two beds that were supposedly the same. I ended up buying a 2” topper that gives the bed a more medium feel. TL;DR Bed was very soft but had to be replaced, replacement was much more firm.
