This ten inch mattress arrived with a promise that it would expand to a full 10 inches in a day or two, as the air had been taken out for the purpose of shipping. But it never expanded to more than 8 inches. It is extremely hard, works well for using the futon as a couch but very poorly for use as a mattress. I had to buy an additional two-inch foam pad to in order for someone to sleep comfortably on it.
