Given the reviews I was optimistic about my purchase, but disappointed upon arrival. The mattress inflated quickly upon opening and unfolding however, as shown in the photo there is a hump about 13 of the way from the head and it extends the entire width of the mattress. Wayfair has a fairly easy way to request an exchange and it was processed quickly. My only complaint is that it didn’t offer me a chance to try a different mattress, it just automatically ordered me the exact same one, which has the exact same problem. The new mattress has the same hump. Now I have no recourse and two defunct mattresses because you can only return a mattress once. Also, this is not a medium or plush mattress. It is firm. We slept on it two nights and my husband loved it. He prefers firm. I like soft.
