My neck doesn’t hurt any more!

I was a little skeptical that a rectangular pillow would work, but by the third night, my neck stopped hurting. I used to wake up in the morning with a crick in my neck, even though I was using an orthopedic pillow. I’ll never go back to another pillow!

We're happy you weren't too skeptical and gave Pillow Cube a shot. And even MORE happy to hear you've seen the light after the end of a good night's rest. Here's to no going back! :)

Love This Pillow !

I ordered the longer 5 in per the guidelines. I really do love it. In time I'd like to get a 4 in height as I think it will bring my neck position down just a bit , I'd had surgery on 3 neck vertebrae and feel it will really be perfect, but I absolutely love the pillow


Pillow Cube

We are pleased to hear you love the pillow. If you do decide you wish to try the 4-inch instead, you are within the 60-day exchange window. Just reach out to our customer care team and we'd be happy to help you!

Comfortable after VOC smell goes away

This is our second one. Comfortable after all the petroleum/VOC smell go away. We had to take off the cover that came with the pillow, leave it in a separate room and rotate once a day to get rid of the smell. Each time it took about 3 weeks. Would be nice if they had foam that's already aired out before shipping to us so we could use it right away. The kneezey did not smell as bad and only took 3 days. Also, for other buyers: don't choose the size based on height chart, measure the gap with a tape. The foam crunches down more than expected, so the second one we got a bigger one for me.

We have found a pillow can have a stronger smell if it was packaged quickly after cutting it. We're happy to hear you found a solution. In the future, we do suggest taking the cover off (as you did), but also placing it outside. Do not leave it in direct sunlight, but if you have a covered area, this can help to speed up the de-odorfying process. Thanks for sharing your feedback with us and helping others!
