Luxurious, plush comfort for every space

Meet the Pillowflex Synthetic Down Pillow Insert, a generous 12x24 inch form designed to elevate shams and decorative cushions. The fill delivers a light, airy loft with a down-like feel, while the shell blends durable polyester and cotton for a refined, smooth touch. This insert is crafted to complement a wide range of covers and rooms, from living rooms to bedrooms.

Perfect sizing for a confident look

Size matters when aiming for a polished silhouette. Measure corner-to-corner of your sham and pull taut along the outer edges. This 12x24 insert is commonly paired with 12x22, 11x23, or 12x24 shams. For a fuller, airier edge, select an insert that is slightly larger than the cover.

  • Inserts should be larger than shams for a full, tailored appearance
  • Pillowflex offers 60+ sizes to fit covers from decorative accents to lumbar and travel pillows

Ultra-soft, versatile down-alternative fill

The synthetic down alternative delivers a plush, cloud-like feel without real down. The exterior shell, a blend of polyester and cotton, provides a smooth, durable surface that maintains shape through daily use.

  • Lightweight loft with down-like fluff
  • Ideal for sofa, bed, and travel setups seeking lasting comfort

Allergy-friendly and care-conscious

Designed with spaces in mind, these inserts are odorless, lint-free, and cruelty-free. They are made without flame-retardants, offering a practical option for comfort-focused rooms without harsh additives.

  • Odorless and lint-free for a clean, low-maintenance feel
  • Cruelty-free materials with no flame retardants

Quality you can trust, made in the USA

Produced in Palmetto, Georgia, this insert pairs responsibly sourced fiber with a durable poly-cotton shell. The result is a pillow form that combines comfort with everyday resilience and a premium look.

Real-life uses that fit your routine

Refresh a sofa, add a polished layer to a bed, or create lumbar support for reading chairs. The insert travels easily for hotel stays or guest rooms, delivering a cozy, well-styled feel wherever you lay your head.
