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 Combo Cube will ship Summer 2025.

    Best Purchase Ever

    I am really not a person that will go review a ton of things, unless I'm really happy or unhappy with a product. The pillow cube is by far one of the BEST things I have ever purchased and it definitely deserves five minutes out of my day to write a review for it.

    I get intermittent muscle spasms in my neck and they. Are. Painful. I have also always been a side sleeper. While the pillow cube is no substitute for medical treatment for neck issues, this pillow is a freaking game changer. I very, very rarely get muscle spasms in my neck anymore and on the days where my neck is warning me one is coming, a good night's rest on the pillow cube fixes it up really well.

    These pillows are durable, too. I thought I had it for right years, turns out it may have only been four - but do you know what? This pillow stands the test of time. After (at least) four years, it has some of those lint balls that form with well loved clothes and furniture, but other than that, it's as good as new. This pillow comes with me on even an overnight stay at a hotel. A night without my pillow cube is a sad night.

    Like I said, I don't usually go out of my way just to compliment a product. The pillow cube is worth it. Yes, it's more expensive than a Walmart pillow. But there's a good reason for that! Worth every penny, hands down.

    4" thick pillow cube needs to be an option again!

    I love my 4" thick pillow cube, went to order another one, and was so disappointed that they only come in 5" or 3" sizes now. Please, please bring back a middle size, as the other 2 sizes are uncomfortable for people who are between larger adult and children size.

    Thanks a cube-ton for the love and for being part of Team 4”! We totally hear you — that perfect in-between size can make all the difference when you’re chasing that just-right neck support. While the 12x24 size Side Cube/Ice Cube only comes in a 5" thickness now, your plea has been officially noted (and passed along to the powers that be). We’re always reevaluating based on customer feedback!

    In the meantime, thanks for sticking with us — we’re rooting for your Goldilocks-size cube dreams to come true!
