    Frequently Asked Questions

    Yes! We can create custom foam inserts for window seats if you have existing covers or plan to make your own. Our window seat foam is cut to your exact dimensions with clean, precise edges. This is a cost-effective option if you only need to replace worn foam or if you prefer to source fabric separately.

    These terms are often used interchangeably. A rectangle cushion refers to the shape, while "bench cushion" describes the application. Most bench cushions are rectangular in shape. When ordering, what matters most is providing the exact dimensions you need and describing where the cushion will be used so we can recommend appropriate foam density and thickness.

    Yes! We create rectangle seat cushions in virtually any size. For very long benches (over 6 feet), we may recommend creating multiple cushions that sit side-by-side rather than one continuous piece. This makes the cushions easier to handle, clean, and store. However, if you prefer a single long cushion, we can accommodate that as well.

    For rectangle foam cushions or square seat cushions used as floor seating, we recommend high-density foam in a firmer density to provide adequate support when sitting directly on the floor. Thickness should be at least 4-6 inches for comfortable floor seating. Some customers prefer layered foam with a firmer base and softer top layer for the best combination of support and comfort.

    Yes! If you have existing foam inserts in good condition, we can create new covers to refresh your cushions. Just provide the measurements of your current foam, and we'll make covers that fit perfectly. This is a cost-effective way to update your look or replace worn covers without replacing the entire cushion.

    Very Satisfied Customer

    My custom made trapezoid cushion was a perfect fit. It was delivered ahead of schedule. They called to verify cushion thickness, and requested I send a photo of the sketch with measurements to recheck. I am very pleased with its appearance and comfort. Great product, carefully constructed and great customer service. I will use again if needed. Thank you. MKHolland Shawnee OK
