For most custom window seat and bench cushions, we recommend firm foam for supportive, structured seating that maintains its shape over time. This is ideal for built-in seating and areas used daily.
If you prefer a softer, more relaxed feel, Ergofill offers gentle comfort with a slightly cushioned finish. It’s best suited to lighter-use spaces or where a softer sit is preferred.
If you're unsure which cushion fill is right for your space, we’re happy to provide guidance based on how your bench seat will be used.
