CANT GO BACK

If I was on a deserted island (with a stream) and could only bring 3 items it would be, this knee pillow, my epipen, and one of those straws that filters water so you can drink from a stream—in that order.

The Weird Pillow I Didn't Know I Need But Now Can't Live Without

I usually just sleep with a regular pillow between my legs. It helps my hips to not hurt, plus I hate my sweaty legs touching. But the problem is that my pillow keeps slipping out in the night. The knee cube one has these like curved cut outs that keep it in place the whole night. I actually have to order another one cuz my wife stole the one I had... 😢

Pregnancy Approved

I’m 36 weeks pregnant and needed something to support my hip alignment in the night. We already use and love our pillow cube pros and have a supportive mattress but I needed something to keep my legs from laying collapsed on top of each other because it would make my hips sore and difficult to get up and out of bed (not like it’s not difficult enough already). This has really helped keep me supported head to toe and I do love the contours to have the capability to change up where you need more/less support throughout the night. I truly believe both the pillow cube and now the knee cube have been essential to getting the best possible rest throughout the night during my entire pregnancy and I hope maybe other pregnant mammas may see this and benefit as well.

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.

    I love it even a year later!

    I bought this knee pillow when I was about 2 months pregnant for my hip pain. It definitely helped! I couldn’t be more grateful for it! Now that my baby is 4 months, I still love this pillow! I love how firm it is! It’s so comforting for my lower back when I’m on my side, for my hips, legs, knees, and ankles! No other pillow can compare.

    I have been loving pillow cubes so much since 2023 that I have 5 of them including this one. Just waiting on yall to restock the combo one to add to my collection!

    This has been the best knee pillow I've had. I was concerned it might not be thick enough, but since the pillow is longer, it provides better support than the smaller indented pillows just for your knees.
