This may not be a fair review, but… I loved the price, appeal, shipping, look of this mattress. It, unfortunately, is killing my back. I’m used to a hybrid mattress but have been sleeping on this, which is on our guest bed downstairs, due to the illness of the season. Maybe I am just discovering that a “medium firm” mattress isn’t for me or maybe this particular one I’ve been shipped is more firm that advertised. I’m disappointed in my choice and hope my guests tolerate it better than I am. Searching for a foam mattress topper to add to it for more comfort.
