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.

    I've had this pillow for about 2 years now and it's kept its form, very low maintenance, and comfortable. I would recommend this pillow for anybody who sleeps on their side.

    Your neck called, it wants this pillow

    Maybe you're like me and think "my neck is so bad, what could this do for me?"

    That's what I thought too. I've used heating pads, lidocaine patches, stretches, pain relievers, basically anything to fix my seized up neck.

    After seeing all the great ads on Instagram, I finally gave it a go. It is like a night and day difference (no pun intended).

    It is difficult to describe what it feels like to lay on it because it is seriously supportive but also so soft and comfortable. I think it might just be magic.

    This would also make a stellar gift for anyone in your life. They will talk for years about how this pillow changed their life.

    This all seems like hyperbole, but it isn't. It really is that good.

    For Chemically sensitive customers

    I bought the 4" cube, and assumed that it would come with some chemical smell, as well as possibly cause a reaction. But I was also motivated to find a better sleep solution, and that eventually paid off. Here's what I did...there was a smell when I unpacked the pillow, and even after the smell wore off, I still felt irritation in my airways when I tried to sleep with it after a few days of letting it off-gas outside. So I put the bare foam outside in the sun for 3 weeks, rotating it so that all sides got thoroughly off-gassed and also sealed by the sun. It worked! The foam changes color when you do that, but that has no impact on the product, and the sleep benefits are great. I'm so glad that I was patient, and figured out what would work for me. You may be able to bring it inside sooner than I did. Either way, it's worth it. Also, you don't need to get the pillow cover. The foam has a zip cover already, and I use a King size pillow case on top of that.

    Oh no! We genuinely regret to hear your Pillow Cube has an odor or smell. Please know all of the foam we use is of the highest quality. Sometimes, if the pillow is packaged quickly after the foam is made, it may have a stronger smell initially.

    However, this smell will dissipate over time. To speed up the process, we recommend placing the foam core in direct sunlight (within your home) and open air until the odor has faded. (Great job thinking about this!) Additionally, washing the pillowcase and cover can help freshen the pillow. Please be sure to leave them to hang dry, so they do not shrink. Remember, the foam itself is not washable!

    We are so happy to hear you stuck it out to give the Pillow Cube a chance and that you love it! Here's to many more nights full of sleep you deserve!
