Best Sleep Of My Life With This Pillow!

Honestly I'm very picky with pillows, all my family members have loved really soft pillows but I always went for firm ones because otherwise my neck hurt every morning. But then in early 2021 I saw an add on Instagram and bought a pillow cube soon after. Now I've had it for over 2 years, much longer than I've been satisfied with any other pillow. Now I'm considering buying another one for when I stay over night at my boyfriend's place cause he likes soft pillows just like everyone else in my life 🤣

Supportive Pillow - Good For Side Sleeper

As a side sleeper, I was constantly plagued by neck and back pain upon waking. I wanted to hold off on sharing my thoughts until I'd thoroughly tested out this Pillow Cube. Having used this product for several weeks, I can confidently say that it has resolved all of my discomfort issues. My first order was for the standard size, but it was too tall for my preference. However, the return process was not only seamless but also environmentally friendly, which I truly appreciated. For reference, I'm 5'3 and weigh approximately 110lbs. I found that the 4-inch version of the Pillow Cube suits me far better.

Does Exactly What I Hoped It Would Do

I’ve suffered from neck problems for many years, and frequently wake up with muscle spasms which, in turn, often triggers migraines. I knew that my old pillow wasn’t working for me, but had no idea what to try as a replacement. After my wife and son both bought Pillow Cubes and raved about them, they convinced me to give one a try. Although it took a night or two to get accustomed to the extra support, I have not had any neck pain whatsoever since I started using it, and I find that I’m sleeping more soundly than before. The Pillow Cube is definitely worth every penny spent - I just wish I had it years ago.

MADE FOR SIDE SLEEPERS, BY SIDE SLEEPERS

Old fashioned pillows are made with cheap foam dumped into a sack. But sleepers need more support, and we will try anything to get it; folding, stacking, nothing works.

Pillow Cube fills the gap between your bed and your head, aligns your spine, and supports your noggin.

What if I sleep on my back and side?

Not a problem. Meet our latest addition to the family, the Combo Cube, coming soon.

Designed for our noncommittal sleepy heads, the Combo Cube is the ultimate pillow for back & side sleepers.

We took our signature Aeropluff foam and scooped out a head-sized valley to cradle your noggin.

    THE REAL DEAL, THANK YOU SIDE CUBE CREATOR!

    For context I am 70 and 7 years ago I had a plate put in my neck and 6 months after that back surgery for drop foot. I am a side sleeper. I have tired and purchased 20 plus over a thousand dollars worth of pillows. Before and after my surgery I have been waking up at 1am-3am due to neck pain, headaches a lot of tossing and turning. I have had a plenty of PT and gotten no help from my annual visit with my primary care physicians. Three weeks ago surfing the net I stumbled on the Pillow Cube, researched and then bought the Side Cube. I am sleeping longer and a lot more sound, not tossing and turning (according to my wife). This pillow has made a great difference in my life…. Thank you for this pillow!

    Can’t sleep without

    A night in a hotel used to sound nice but now that I’ve gotten so used to this pillow anything else feels like a flat sheet! I love this little pillow so much that I bought the travel version too. Love this pillow!

    Best pillow ever

    This has been the best pillow. I have no curve in my neck so side sleeping is a must but pillows are never thick enough or too hard. This pillow changed my life and helped tremendously with my neck and back issues. However I’m back online trying to buy again as ours have gotten older and aren’t as supportive anymore and the 4” option is gone!!! I don’t like the new foam they use in the deluxe as it’s the same as the travel pillow and not as supportive and the price is way higher. Where is the regular 4” option ???? The others would be too tall or too short. Why would you leave out all the people who need the 4”??? 😕 please bring them back! My neck is begging you🙏🏽

    We’re so glad to hear how much the Side Cube helped with your neck and back issues—that kind of feedback is exactly why we do what we do. We hear you loud and clear on the 4" size and at this time, the 4" size isn’t available, but your feedback is incredibly important to us. We’ve shared it directly with our product team and are actively exploring ways to better serve sleepers who fall between the current sizing.

    In the meantime, thank you for sticking with us—we truly appreciate your support and your neck’s passion for proper alignment!

    Best decision of my life!

    I suffered from back, neck, or shoulder pain and this pillow stopped all of it! It’s not dense or heavy like other pillows. 100% recommend
