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, 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 never dream

    Until now, I never used to dream. Once I started using the Pillow Cube, I began dreaming every night. At first, I thought it was crazy, so I waited a few months before writing this review, but it's real. I love my Pillow Cube. I bought the side cube for my wife, and I also have a travel cube. Incredible!

    The G.O.A.T Pillow

    I had a travel size pillow cube for a year that I used at home. I told my wife I’d never lay on another pillow again. Then we took a trip to two destinations and I lost it in transit. I had headaches for days until this upgrade deluxe version arrived. Now I’m back in heaven when I sleep. It can fit two heads on it honestly. But will need another travel cube because this is too big to travel and I can’t sleep on regular pillows anymore.

    It sounds like the Side Cube Deluxe has really stepped in to save the day after losing your travel pillow—glad to hear it’s become your new go-to! It’s awesome that it’s providing that next-level comfort at home, but we totally get how the smaller travel size is ideal for trips. Thanks for sharing your experience, and we hope you get your hands on a new Travel Cube soon for the ultimate comfort wherever you go!
