Ready to refresh your throw pillows? This OOSTAR 16x24 inch rectangle pillow insert is exactly what you need to bring new life to your pillow covers! The dimensions (16x24 inches, or 40x60 cm) make it perfect for those longer lumbar pillows that provide such great back support on couches and beds. What I love is how well-stuffed it is with high-quality polyester cotton - it's fluffy and plump without being overstuffed, so it maintains a beautiful shape that's perfect for both decorative purposes and actual comfort. The brushed chemical fiber fabric cover feels soft against your skin, and the zipper closure is such a smart feature because it lets you see the quality of the filling inside and adjust the loft if needed. Unlike those sealed pillow forms that you can't adjust, this design gives you control over the firmness. Just a heads up - it's hand wash only rather than machine washable, but the good news is that drying it in the sun or a dryer helps restore that fluffy shape beautifully. It might take 3-7 days to fully fluff up after unpacking, but once it does, it provides amazing lumbar support and looks fantastic in any pillow cover. Such an affordable way to upgrade your home decor without replacing all your pillow covers!
