This is my third futon mattress in 5 years, and at last what seems to be a good one, for sitting at least. First two were fam and the stuffing. Neither comfortable for sitting although foam was okay for sleeping. This one is a hinged inner spring. Seems well made (in USA), but I've only had it a week. No odor and no bed bugs. If it lasts a few yeats, I'll be well satisfied and so would you.
