We ordered this along with the Camrynn Vegan Leather Upholstered Metal Slat Bed with LED Light, USB Port and 4 Drawers for my teenage son who was complaining about outgrowing his twin bed. The mattress is super comfortable. The mattress expands (it's wrapped in thick plastic and spreads out and thickens up once opened) and the box is very heavy before the mattress is released.
