Air 4DX high

For many years, I struggled to wake up feeling refreshed in the morning, so I chose a Nishikawa pillow, hoping that a more functional one might improve the quality of my sleep.
I was wondering whether to choose the AIR 4D high or low setting, but I'm glad I chose the high setting. The reason I chose the higher one is because I can adjust the height myself. If it's too high, I can remove the inner cushion to lower it.
I always sleep on my side, and it provides just the right amount of firmness to support me.It's so good to use, I plan to buy it for my family too.

Absolutely in love with it!

I'm absolutely in love with this pillow! I immediately noticed all the attention to detail. First impressed by the delivery, it arrived neatly packaged in a sturdy discreet box with a carrying bag, perfect for storage or travel.
I love how comfortable it feels, especially on my neck. Instant relief. It’s just the right amount of firmness for me, my head doesn’t sink in. I love that it hasn’t lost its shape at all so far. Bonus point for the cover, very smooth and easy to remove for a wash. My new favorite pillow!!

This Pillow Saved my Neck!

It took a few days to get used to but after about 3 days, I noticed my neck was much less creaky upon waking. As a side sleeper, I’ve had much trouble finding comfy pillows for my neck. After a week, sleeping like a baby. I chose the high - air 4dx. So worth the $. Will certainly save me $ in chiropractor bills:) P.s. it also fits my standard size silk pillowcase.

FAQs

Some fabric sprays may cause the pillow's fabric to discolor. Test a small area first to ensure it will not stain. Also note that if the pillow is damp from the spray, mold or urethane deterioration may occur. To prevent this, make sure the pillow is completely dry in a well-ventilated area before use.

Because of hygienic reasons, we recommend replacing your pillow every 2 to 3 years. We also recommend replacing the pillow when you feel that the head part has worn out.

No. Check the reverse side, and use the pillow so the AiR logo is on the bottom side (near the shoulder).

The stuffing (inner core and adjustment sheets) is not washable. The outer fabrics are washable.

It is best to air dry the pillow in the shade, avoiding direct sunlight. Place it in a well-ventilated area in your room to avoid moisture build-up.
