Adjustable Pillow: 5 Reasons to Set Your Own Height With the Tune
1. You set the height instead of guessing it.
An adjustable pillow has loose fill you can add or remove, so the height is yours to decide. Open the zipper on the Tune, take out or put back shredded foam, and close it. A fixed pillow gives you the height it was made with.
It takes about five minutes. Lie down, check how it feels, and adjust again if you need to. There is no need to get it right the first night; the fill you take out is not lost.
2. The range runs from 2 to 6 inches.
The Tune adjusts from about 2 inches with most of the fill removed to about 6 inches with all of it in. The fill is shredded memory foam, so it shapes around your head rather than staying as one block.
As a starting point, keep most of the fill for side sleeping, remove some for back sleeping and remove most for stomach sleeping. This is a comfort and positioning product, not a medical device. Comfort varies by sleeper and mattress.
3. The cover comes off and goes in the wash.
The white quilted outer cover zips off. Machine wash it cold on a gentle cycle, then air dry or tumble dry low. Take the cover off before washing so the fill stays dry.
Never wash the foam fill; spot clean it only. Fluff the pillow each day to keep the fill evenly spread, and air the foam for a few hours every month or two.
4. One pillow covers three sleep positions.
The Tune is 26 x 18 inches. Because the height changes with the fill, the same pillow can be set high for side sleeping, lower for back sleeping and nearly flat for stomach sleeping.
That also means it can change with you. A new mattress, a different sleep position or a second person using it are all a five-minute adjustment, not a new pillow.
5. The spare fill has its own storage bag.
A storage bag comes with the pillow for the foam you take out. Keep it somewhere dry and you can put the fill back later. Fully loaded, the pillow holds about 1,000 g of fill.
Start by removing a handful at a time rather than half the pillow. Small changes make a clear difference, and a handful is easy to put back.
BONUS: Give it a few nights before you decide.
A new height can feel unfamiliar on the first night. Sleep on it for a few nights, then add or remove a little more. Keep the storage bag closed so the spare fill stays clean.
