This is a Basic Starter Futon Mattress which will give you the best value and comfort possible at this price. It's great to throw on the floor for an unexpected guest or for kids, but you'll probably feel the bars on a Metal Futon Frame. It starts out with 6" or 7" of material, and if you picked it up from us it would measure at least 6", but with the way we vacuum pack it for shipping it may arrive measuring half that size, or can compress to that size with use. Cotton Batting Surrounded by Polyester Fiber Soft Black Twill Cotton Poly Covering. 60" X 80" 5" Thick, 55 Lbs. This mattress has a 1 year warranty against defects in zippers, seams, and tufts, and excludes misuse, or abuse. Stains of any kind void the warranty. You do need to rotate the mattress on a monthly basis to keep it even and level. For any warranty issues the customer is responsible for all shipping charges.
