                  Custom Size & Shape Pillow Inserts

                  Made-to-order down or polyester inserts designed to perfectly fit your decorative pillow covers.

                  Not every pillow requires foam pillow inserts for the best results. Our custom down pillows offer a light, fluffy softness for luxurious comfort. Down pillows are often used to fill decorative fabric cases. Down is the only filling that allows the karate-chopped look in the middle of a down pillow, making for an elegant look on beds and sofas. Custom pillow inserts from FoamOrder.com make it easy to create DIY down pillows or restore a favorite pillow that has gone flat over time.

                  Why Choose Custom Size & Shape Inserts?

                  Standard pillow inserts often fall short — literally. They leave corners sagging, edges under-filled, and decorative pillows looking less polished. Our custom inserts solve that problem by letting you order precisely the size and shape you need. From classic rectangles and lumbar bolsters to round, right-angle, or equilateral triangles, we make inserts in virtually any configuration to match your pillow covers.

                  

                  • Custom dimensions: Enter exact width, length, diameter, or side measurements for a perfect fit.
                  • Multiple shapes: Choose rectangle, bolster, sphere (round), right-angle triangle, or equilateral triangle.
                  • Better appearance: A properly sized insert fills out corners, maintains shape, and improves loft.
                  • Long-lasting support: Quality materials hold their structure over time and extend the life of your pillows.

                  

                  Choose the Right Fill for Your Needs

                  We offer a full range of fill options to match your budget, softness preference, and performance needs — from cost-effective synthetic to premium goose down.

                  

                  Polyester

                  A soft, hypoallergenic, and affordable alternative to natural down. Polyester inserts are ideal for decorative pillows in living spaces, guest rooms, or anywhere you want a clean, low-maintenance fill.

                  

                  Grey Duck Down

                  Available in four blends, each with a different balance of softness, loft, and cost:

                  

                  • 10/90 Down: 10% down, 90% feathers — supportive and economical, with a firmer feel.
                  • 25/75 Down: 25% down, 75% feathers — a versatile mid-range option with balanced softness and structure.
                  • 50/50 Down: Half down, half feathers — plush comfort with noticeable loft, ideal for high-end accent pillows.
                  • 100% Down: Pure down fill with exceptional softness, breathability, and resilience — the most luxurious option in this category.

                  

                  White Goose Down

                  Our most premium fill choice, known for exceptional loft, lightweight feel, and long-lasting durability:

                  • 50/50 Down: A premium blend that offers a plush, buoyant feel while maintaining shape.
                  • 100% Down: Ultra-soft, naturally insulating, and incredibly airy — perfect for luxury decorative pillows.

                  

                  Sizing and Ordering Tips

                  • Order slightly larger: To ensure a full, tailored look, order your insert about 2 inches (5 cm) larger than the cover. For example, a 20" x 20" cover pairs best with a 22" x 22" insert.
                  • Measure flat and empty: Dimensions are measured with the insert lying flat and unfilled. Once filled, the insert will expand and shrink slightly.
                  • Lightweight fabrics: If your cover fabric is especially light or delicate (like silk), order the exact size rather than sizing up.
                  • Extra loft option: You can add an optional 15% extra fill for a plumper, more structured look.

                  

                  Shapes We Offer

                  We make inserts in virtually any configuration to match the covers you already own:

                  

                  • Rectangle: The most common insert for standard throw pillows and back cushions.
                  • Bolster (cylinder): Great for lumbar support or decorative layering.
                  • Sphere: Adds playful dimension to modern décor.
                  • Right-Angle Triangle: Ideal for geometric accent pillows.
                  • Equilateral Triangle: All-sides-equal shape for unique design pieces.

                  

                  Care & Longevity

                  All down and feather blends are encased in a high-thread-count down-proof fabric that prevents leakage and maintains fill distribution. To maximize your inserts’ lifespan:

                  

                  • Fluff occasionally to maintain loft.
                  • Spot clean when possible and allow to air dry completely.
                  • Use high-quality covers to protect from wear and stains.
