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.

Designed for our noncommittal sleepy heads, the Combo Cube is the ultimate pillow for back & side sleepers.

We took our premium cut AeroFoam and sculpted a head-sized valley to cradle your noggin and keep your neck aligned, no matter how you sleep. Then we leveled it up by adding modular risers, giving you the ability to customize the height of your pillow to match your body, mattress, and sleep style.

    Will never be able to live without it

    I got my side cube deluxe as a Christmas present over a year ago and have been sleeping on it since. I have been obsessed with it and feel that it’s something I can’t live without. I’ve traveled and forgotten my pillow cube a few times and had a use hotel provided pillows and ive found I simply can’t sleep on a regular pillow anymore. While it is expensive for a pillow I have to say it is worth it. To say the least, it has changed my life!

    That’s the kind of dependency we’re totally okay with.

    We love hearing that your Side Cube Deluxe has gone from Christmas gift to absolute non-negotiable. Forgetting it while traveling and being forced back onto hotel pillows is a special kind of betrayal — once you’ve gone Cube, there’s really no going back.

    Yes, it’s an investment, but when something genuinely changes how you sleep (and basically ruins regular pillows forever), we’d call that money well spent. Thanks for sharing your Cube obsession and letting us be part of your nightly routine — life without it just isn’t the same.

    I should’ve bought this pillow years ago.

    I can finally side sleep like I’m supposed to.

    Also, who invented regular pillows that one isn’t enogh, but two is too much?

    Now *that* is a realization we hear a lot — usually followed by “why did I wait so long?”

    We’re thrilled the Side Cube Deluxe is finally letting you side sleep the way your neck and shoulders always wanted you to. Once everything lines up properly, there’s no going back. Thanks for joining the side-sleeping upgrade club and sleeping like you’re supposed to!
