Will Speed-Sew work on a mattress seam rip?

Can it? Well, Speed-Sew is a fabric glue that can mend ripped jeans or torn clothing permanently. Let’s give it a try. Locate the seam rip where the stitching has come undone and apply Speed-Sew to it. Pinch the area together and wait for several hours. After that, give it a tug to check if it holds up. Speed-Sew works great as a fabric mender, so it’s definitely worth trying on a mattress seam rip. Give it a go!
