Adjustable pillows are easiest to fine-tune if you change one small handful at a time. Keep the fill you remove, close the pillow fully, and judge the result with your head resting on it. An open pillow held in your hands tells you little about how it will feel on the bed.
Find the fill opening
Take off the pillowcase and locate the inner liner. Some pillows have one zipper for the washable cover and a second zipper for the chamber holding loose fill. Others adjust by adding or removing a whole insert. Check the label or manual first. A sealed pillow or a solid foam core should stay intact.
Remove or add a small amount
- Put the pillow flat on a clean table or bed. Set a clean, dry bag or container beside it before opening the liner.
- Open the liner just far enough to reach in. Remove one small handful if the pillow is too tall, or add a little of the compatible spare fill if it is too low.
- Record the change. A count of small handfuls is enough if you use roughly the same amount each time. Save removed fill in the bag so you can reverse the adjustment.
- Close the inner zipper and redistribute the fill. Fit the cover and pillowcase before testing so the pillow feels the way it does at night.
Test height and feel separately
Lie in your usual position and follow the pillow height check. If you change positions during the night, try both before removing more fill. Adding fill can raise the pillow and make it feel firmer because the contents have less room to move. If you like the height but feel a lump, redistribute the fill before changing the amount.
Try the new setup while you settle in for bed. If it feels worse, put some fill back. A pillow that looks uneven after you close it may simply need its contents spread into the corners.
Keep the leftover fill dry
Store the fill in a labeled, closed bag away from moisture. Follow the maker’s instructions before cleaning the shell or fill. The Coop adjustment demonstration shows how a zippered loose-fill pillow works. Instructions vary by design. See our pillow washing and replacement guide for more on care labels and drying.
