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.

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.

Our customers report that they get better sleep, wake up pain free and full of energy.



What if my partner sleeps on their back or stomach?

Designed with precision, our pillow not only cradles the heads of side sleepers but also offers optimal neck support.

    Contemplating the back/side sleeper pillow that will be released in April. My fingers still feel numb in the morning like my neck is kinked because I fall asleep on my side but end up waking up on my back. Still, this is the best pillow I have found in a LONG time. Definitely would recommend to anyone looking for a new pillow. Stays cool and keeps its shape. I also have the knee pillow, and I will never not have a knee pillow again. Game changer!
