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, now available for pre-order.

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 is a pre-order & is estimated to ship April 2025.

    Great pillow, but more sizes should be offered again.

    This pillow used to be offered in three thicknesses, like the current deluxe model. These options are crucial in getting the proper fit and benefit from the Pillow Cube. At 6’2”, I assumed that the standard 5” pillow was the proper size for me, but after a couple of months, it started to feel a bit too thick (I was waking up with neck and back pain). So I tried a 4” pillow, and have zero issues ever since. I’ve also suffered from sleep apnea for a number of years and was snoring excessively, but since using the Pillow Cube, it’s drastically reduced the snoring (as my poor wife can verify). It seems that keeping your head and neck aligned with the rest of your spine has even more benefits than I first imagined. As I stated, however, not everyone will find the standard thickness optimal for their needs, so the original options need to be offered again. I plan on purchasing another 4” pillow (like the one I’m using) for my wife, if and when they again become available. She already tried the standard size that I was initially using and also found it too thick. I’m hopeful that these will be restocked in the near future. Overall, this is a great pillow that’s very well made and retains its shape and support even after much use. I highly recommend it, and I wouldn’t sleep on anything else.

    I really like my cube, honestly.

    I like that it doesn't slide around and that it's a flat surface that my face can't sink into and suffocate me when I'm lying on my side. The flat surface is also great for propping my hand up while I'm scrolling tiktok, and for not blocking my view when I use my flexible phone stand to play youtube videos. I never feel like my ears are getting squished, and I never feel like my head is basically resting on the bed. I do wish there was a slightly taller version for when I have to prop myself up due to heartburn, but I just place a firm pillow underneath it and that works fine. overall it is very nice and high quality.

    Perfect pillow for side sleepers

    I adore my Pillowcube. I am a dedicated side sleeper whose previous pillows have always been so flat I had to stick my arm under my head to be comfortable. I got C**p based on reviews and it’s a great pillow but not for me. I kept waking up all night to push it back under my neck.

    The Pillowcube is the perfect height and stays that way all night. I roll from side to side and it stays perfect. I can put my arm wherever I want, which is good for my shoulders. I’m getting great sleep and don’t wake up with cricks in my neck and shoulders! It’s a game changer for me!!! Thank you!!
