Fine. It was easy inputting the extra fill into the pillow. I placed it in the center giving it a bit more support there. I like a very firm big pillow! Was great and I will add something that your pillow fill has no out gas odor!!!
I was a true skeptic about these pillows. It is true they have a smell for a little while but it does go away and I am sleeping better than I have in years!
I purchased the COOP pillow almost two years ago and absolutely love it! I am adding a little extra refill to my COOP pillow, doesn’t need much since it holds up so well and did not flatten as some other memory foam pillows do. Plenty of refill left over for future use. I plan on purchasing another pillow since it is one of the best on the market. No chunky foam like other brands. I sleep so much better and I highly recommend it. Great service and shipping was quick.
