Poly Bun Replacement Filling

Loose Poly Pillow Bun Insert
Poly Bun Insert

Perfect for DIY projects or reviving old pillows, a poly bun is simply loose polyester filling enclosed in a cotton casement (or bun). This creates a soft "inner pillow" that fits inside your new fabric shell or existing pillow covers. Poly buns can tolerate the outdoors and can easily be removed for cleaning or switching out pillow covers. Polyfill is mold and mildew resistant.

Poly bun dimensions are based on measuring along the cut edge, not the width. Once filled with poly fiber, the height and width will be slightly less than the measurements ordered. For example, a 12" x 12" poly bun will have finished dimensions of 11" x 11".

Barbara August 1, 2026
I have non-standard size Sunbrella cushions and the seats were good, so I just needed inserts to the seat back cushions that are water resistant/made for outdoor. They arrived and fit beautifully. This was so much better than replacing all of the cushions. I couldn’t be more pleased. Highly recommend.

It took us awhile to find out where to order replacement for our Sunbrella cushions. We found Cushion Source and everything was delivered as expected, and process was easy as well. Thank you!
