I ordered some rectangular shaped foam back in early March to replace the foam in my sofa cushions. Having the shapes on the homepage made the whole process super easy. I measured the length I needed for the cushion pieces and just plugged the dimensions in.
I had contacted their customer support and asked for a recommendation for the right type of foam to use. They said High Resilience foam as it's the most comfortable and longest lasting for sofa cushions. I went with their recommendation and am pleased with it. The foam arrived promptly and so far is holding up great.
