Need to rebuild a seat cushion or create a custom pad? This GoTo Foam slab is your answer. It's a big piece measuring 5 inches thick, 50 inches wide, and a full 90 inches long, giving you plenty of material to work with. The firmness is rated at 44 ILD (Indentation Load Deflection), which is a medium-firm feel – supportive enough for seating but not rock-hard. It has a density of 1.8, which is a good indicator of durability. The company says it's built to last 7 to 10 years with normal use. Made right here in the USA. This foam is super versatile: perfect for re-upholstering old couch cushions, boat seats, car interiors, making bench pads, or even creating a custom floor mattress or play mat. It cuts easily with an electric knife or serrated blade to any shape you need. A high-quality, bulk foam solution for your DIY furniture projects. Say goodbye to saggy, lumpy cushions and hello to firm, comfortable support!
