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.

    Rated 5 out of 5 stars
    works well for side sleeping position

    This provides good head support for side sleepers and is more comfortable for me in the side position than a regular pillow. It seems to align my head/neck area better. I sometimes sleep on my stomach, and it's a little more uncomfortable than a regular pillow in in this position, although not the recommended sleeping position with this pillow. However, I do sleep more on my sides when using this pillow.
