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.

    Now *that’s* what we like to hear — the Side Cube Deluxe stepping in like a tiny foam superhero and telling your shoulder pain to take several seats.

    We’ll happily accept the “best pillow in the whole world” crown and display it somewhere very visible so the other pillows know who’s in charge.

    So glad you’re waking up pain-free and properly pampered! Keep enjoying those sweet, aligned mornings.

    Pillow stacker no more!

    Total side sleeper here and a lifelong pillow-stacker. I usually wake up in a hot mess of pillows everywhere and me clutching one sad survivor. I ignored it for years until my arm started falling asleep. Enter Pillow Cube for the win. I have been sleeping on it for a week and love it. Best sleep in years. Highly recommend.

Your Side Cube Deluxe is clearly doing its job perfectly, giving you the precise support you need without all the chaos. Here's to many more nights of amazing sleep and mornings where you actually wake up refreshed instead of hunting for scattered pillows! Welcome to the cube life! 💙

    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!
