Inside a Mattress Factory: How Polyurethane Foam Is Made (Full Process)

Ever wondered how a mattress is really made? In this factory documentary, we follow polyurethane foam from two liquid chemicals to a finished, rolled, boxed mattress. You'll see how the foam is mixed, how it rises into a giant block, how it's cured, cut, tested, layered, stitched and packed for delivery. In this video you'll see: ✔ What polyurethane foam is made of (polyol, TDI, water, catalysts, surfactant) ✔ How the mixing head and conveyor create giant foam blocks ✔ Why foam gets hot while it cures ✔ How foam is cut with band knives, peeling machines and computer-controlled cutters ✔ How egg-crate foam is made ✔ Quality control and durability testing ✔ How mattresses are layered, stitched, compressed, rolled and shipped If you enjoy factory tours and "how it's made" videos, subscribe for more manufacturing documentaries.
