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.

    Could no believe it!

    All my life I have tried to find consistent comfort laying on my side in any kind of pillow I could find. Well look no further. This is it. I chose and ordered a 5 inch pillow height and it’s perfect to lay on my side all night. No waking up to get re-situated. You can actually sleep all night with this dream pillow! Thank you!

    Goodness gracious

    Here's the thing: I bought the ice deluxe side cube last Christmas for myself and have spent 10 glorious months loving it and doing everything short of standing on a street corner with a megaphone screaming at strangers about how awesome my pillow is. Eventually, my partner wanted one for their side of the bed. I waited for a text from PillowCube with a discount code and then I jumped on it. The "Side Cube" came, perfectly packaged... but I instantly realized that it is much, much softer and smaller than my Big Boy Ice Deluxe. I was disappointed and planned to send it back to get a second Big Boy. But then I decided I'd AT LEAST lie down with Side Cube to compare. Imagine my surprise when I almost instantly fell asleep and did not wake up until morning. It was The Best Sleep of My Life! Turns out the smaller, softer Side Cube is My One True Pillow Love. You can pry this pillow from my cold, dead hands.

    Pillow Cube = Awesome

    I've tried every type of pillow that's made, including traditional, water, adjustable fill, and chiropractic. The pillow cube, 5" height for me, balances firmness, comfort, and ideal side sleeping posture which reduces discomfort and increases early morning flexibility. I highly recommend it!

    Durable & comfortable

    My significant other surprised me with the cube pillow on my birthday 3 years ago and I absolutely love it so much I cannot sleep with any other pillow since then. This pillow has in fact helped with my constant migraines and neck tension. My partner also tries to sleep on it himself so I would definitely be purchasing another!
