Made a great pillow better.
Had an awesome pillow but if I didn't fluff it before going to sleep my neck would hurt the next morning. Ordered this and put about 70% into a cardboard box to expand then shoved it into my pillow. Its been great 👍 put the rest in another pillow. Had no scent. My pillows are king sized.

Great for refreshing old memory foam pillows
Our memory foam pillows are 2 years old and need a little refreshing. We purchased this and was able to refresh both pillows to firmer than new condition.

Easy to use
I recently got one of those large body pillows that people usually use for pregnancy. Unfortunately, it was a little understuffed for my liking, and it isn't stuffed/stitched in a way that keeps the filling from moving around. The filling was bunching in places and sparse in others, causing it to be uneven. Fortunately, the pillow had a cover, and the core had a zipper where I could easily access the stuffing. I decided to try this filling to make up for the gaps. It worked great. I grabbed the stuffing and put it directly into the pillow. I did not allow it to expand fully before stuffing. I probably should have. But this was super easy to use and absolutely solved my problem. It doesn't smell great. There is definitely some smell that could probably be cleared by leaving it to air out for a while. I stuffed it right into the pillow and didn't use it until later that night. It wasn't so strong that it could be smelled through the pillow covering and the pillowcase.
