Square Decorative Pillow Insert - 95% Feather 5% Down - by ComfyDown

For a luxurious and full looking decorative pillow, you'll need to get an insert that is 1 to 3 inches larger than the cover.  Typically, small square covers and most lumbars require an insert that's only 1 inch larger, while large square covers require an insert that's 3 inches larger. Most medium square covers require an insert that's 2 inches larger. Refer to our list below to find the specific recommended insert for your size cover. If you're not exactly sure what size your cover is, use our measuring guide.
