    Outstanding sleep!

    I’ve been sleeping on my Pillow Cube for over two weeks now and I have been able to track my better sleep on my fitness watch. I’m no longer waking up in the middle of the night, multiple times, to adjust my “normal” pillow, my stiff neck has gone away and I’m sleeping through the night not tossing and turning. I highly recommend this to any side sleeper who wants a better night’s sleep.

    HOLY CRAP THIS THING ACTUALLY WORKS.

    I have been on a never-ending quest to find a pillow that doesn't give me neck pain and a tension headache from clenching my jaw all night. Day one with this pillow I laid down to take a twenty-minute nap... woke up two hours later.... LIFE CHANGING. The tension in my neck and behind my ears is gone. It's so soft and comfortable. JUST BUY THE PILLOW. JUST DO IT. IT'S WORTH IT.

    LIFE CHANGING

    For over a year, I had neck and nerve pain radiating around to the back of my head from sleeping with regular pillows. I tried every pillow I could find. I finally broke down and spent the money on this pillow. WORTH EVERY CENT! Within a week of using this, the pain was completely gone. 10/10 would recommend!

    I love it so much I take it on trips with me

    I used to have neck pain waking up, or overall discomfort with my head and neck while I slept. I've been using my pillow cube for about 4 months now and I won't turn back, it's the best pillow I've ever used. I actually have the 4" pillow and it's perfect for sleeping on my back (and my side). And yes, I bring it with me camping and on trips cause my sleep is so much better with it haha!
