Knee Cube

$49.99 USD

The Knee Cube helps you get better sleep by alleviating pressure on your hips, knees, and ankles. It also helps your lower back stay aligned so you don't wake up in pain. 

Unlike other leg pillows, the Knee Cube is designed to run the entire length of your legs, ensuring those sweaty flesh tubes don't touch during the night.

Better yet, we've upgraded it with our premium temperature-regulating memory foam to keep everything nice and cool.

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, now available for pre-order.

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

The Combo Cube is a pre-order & is estimated to ship April 2025.

    I have had a Left knee replacement, and recently a spinal fusion. The amount of pillows, foam shaped blocks, and even blankets I have tried out just to gain relief is daunting. The Pillow Knee Cube has been amazing. You can use it in many different positions to gain relief and comfort. I highly recommend the Knee Cube to all my friends and family.
