I used their dense foam for my dining room chairs. They are just peachy. My chairs have a decorative front corner cutout. I didn't trust myself enough to cut that well so I made a cardboard template and took the foam pieces to my local upholstry shop and had them cut to the exact shape. Did piping and side piecing and stapled to the bottom board from the chair. They came out really well, if I do say so myself, and have held up well for the last 5-10 years.
