Smarter 1 Oversized Design: Pillow inserts are intentionally cut 1 larger than standard (labeled 18x18 but actually 19x19 ) to better fill your decorative pillowcase. Just choose the insert size matching your cover – no guesswork needed! Versatile Pillow Inserts: These cushion cores work in any room—your sunny breakfast corner or relaxed evening lounge. They keep perfect shape inside linen covers for daytime brunch, under velvet casings for cozy reading, or within outdoor-friendly fabrics on patios. Filling Mixing: Tested 75% natural feathers + 25% microfiber blend combines moldable comfort and ergonomic support. The dense feather clusters shapes to your curves, while microfiber provide rebound resilience. Temperature-Balancing: Hollow feather quills create more airflow vs. most synthetic materials fills. Feathers naturally have moisture-wicking, while the addition of some microfiber is more adaptable to various seasonal changes. Hassle-Free Care: Machine washable in cold water. Reactivate loft by sun-drying or low-heat tumble drying. For best results, you might try fluffing it monthly – this can help with comfort and make it last longer.
