  • Premium foam core: Aero foam core which offers supportive, pressure-relieving comfort and breathability.
  • Comfort where it matters: Soft middle relieves ear pressure while supporting the head and neck for side sleeping.
  • More pillow, better value:  Get the same Side Cube performance at a better value.

  • Fast recovery & setup: Ships compressed - allow 24–48 hours for full expansion; do not wash the foam core.

The Side Cube Original comes in standard 5" height that fits most adults. If you sometimes sleep on your back, consider a different model or the Combo Cube for mixed sleepers.

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.

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

We took our premium cut AeroFoam and sculpted a head-sized valley to cradle your noggin and keep your neck aligned, no matter how you sleep. Then we leveled it up by adding modular risers, giving you the ability to customize the height of your pillow to match your body, mattress, and sleep style.

    I thought this was a gimmick

    I had terrible neck pain for some time, and thought my sleeping position may have to do with it. I tried pillow after pillow designed for side, sleepers and thought this one might be a TikTok fad. I don’t think this pillow is for all side sleepers, but it worked for me! That plus an additional pillow under my top arm is what did the trick. i’m pain-free now!

    I love thing. Ive tried so many side sleeper pillows and this is by far the best.

    Note, not for even a little back sleeping. I keep a standard memory foam pillow nearby for when I absolutely need to sleep on my back.

    So glad I finally ordered mine!

    I can’t recall exactly when I first heard about Pillow Cube, but it was several years ago. I thought it sounded cool, but never brought myself to place the order. In the time since I discovered Pillow Cube, I’ve purchased two “memory foam” pillows which were decent at best. Well, recently I noticed I was experiencing some neck pain. As a side sleeper with broad shoulders, my head almost always would be at an angle on my memory foam pillow. This would result in pain and discomfort. This year for my birthday, my wife asked what I wanted. I decided it was time to place the order for the Pillow Cube. Laying down on it for the first time is breathtaking; the comfort is immediate. I can feel that my neck and spine are in a straight line and it feels so natural. I’m a big fan and I’m so glad I finally ordered one!

    No more pain

    I don’t write reviews, but I made an exception for this awesome pillow. I have very broad shoulders so the area between my neck and the end of my shoulders is very large. My whole life I have spent stuffing and restuffing that area all through the night to stay comfortable, but no more. I sleep through the night and wake up refreshed. Thank you for this amazing pillow!!!!

Finding the right support for broader shoulders can be a real challenge, so it’s amazing to know this has made such a difference in your rest and mornings.

    Thanks again for your kind words — we’re so glad you’re sleeping better! 🛌✨

    Great after years of use!

    I got my pillow cube 3 years ago when a friend recommended it to me! I used to wake up with significant neck, shoulders, and back pain, and now I don’t using this pillow! It has held up very well.
