Finally A Memory Foam Pillow That Actually Helps!

After near 15 years wasting hundreds of dollars trying to find a pillow that not only supports my neck with comfort, but ALSO my arms and shoulders, I have found it in the Side Cube Pillow, Side Cube Pillow Deluxe and Ice Cube Pillow! Yes, I have purchased ALL three so I'll never be without comfort when I sleep and I can change them up each season depending on the crazy weather here in Colorado! When I use my pillow cube to sleep, I am perfectly elevated from putting any pressures on my arms, shoulders and neck because of this ingenious design! Elevated, but also comfortably cushioned! If you are a side sleeper like me, I encourage you to try this pillow. It's unlike any other pillow on the market and any copies out there do not use the same high quality memory foam and material!

Extra Surface Area Is Nice

I like the increased surface area on this one. The only thing that sucks is now i have to get another one to match cause my old side cube looks dinky next to it.

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.

    Side Cube Deluxe
    Rated 5 out of 5 stars
    Great pillow, all things considered.

    I really did love this pillow while I was on my side, but oddly it showed me that I in fact spend a small amount of time sleeping on my back. This made the side cube not ideal for me, but I really can't stress enough how comfortable this pillow is while on your side. I was able to sleep with my arm down instead of curled up under my head like normal.

    With that being said, I was still very pleased with the high quality of the Sidecube Deluxe and the fitted pillowcase was very nice as well. Even though it didn't work out for me I still say this is a great product, and I believe in it. The problem wasn't Pillowcube, it was me.

    Wow, talk about a plot twist — your Side Cube Deluxe turned into a sleep detective and revealed your secret back-sleeping habits! 🕵️‍♂️ We love that it gave you those perfect side-sleeping moments with your arm finally getting to relax instead of being your makeshift pillow.

    Thanks for being so honest and still believing in what we're doing, even though your sleep style had other plans. Here's to you finding your perfect sleep match, whatever position that ends up being!

    Game Changer!

    I travel a lot, and I have never slept so good in a hotel or on a cruise ship since I bought this almost a year ago. No more waking up with a sore neck/ back or feather allergies from hotel pillows. This fits me just right, and I know who has used it before me. I keep checking to see if you will make your amazingly soft pillow cases to fit this one too. Love those too!

    Hey, Travel Guru! 🌎✈️

    Sounds like your Travel Cube has officially taken first class in your sleep game — no more sore necks, back protests, or feather drama. Love hearing it fits you just right!

    As for pillow cases… we see you drooling over that soft magic. 😉 While we don’t have a Travel Cube-specific case yet, we’re definitely taking notes — maybe one day your cube can rock a matching outfit.

    Thanks for trusting your neck (and your hotel rooms) to us. Keep globe-trotting in style!
