My throw pillows were looking quite sad and flat, so I needed some new inserts to perk them up. I chose these Ant-Home down pillow inserts because I liked that they have the OEKO-TEX100 certification. In researching, I found that the general rule of thumb is to use inserts that are 1"-2”larger than your pillow cover. | got the 18" X 18" pillow inserts for my 17" square pillows. I think a size 2" larger would have been better for more filled out pillows covers. That's not the fault of this product though, and it's really a preference. They are definitely fluffier than what I had before, and the pillows appear to have strong stitching and no feathers poking out.
These pillow inserts seem well made, and so far, they are doing their job well. My throw pillows look and feel better now. I recommend them and think they are a good buy.
