Essential For Bed Sharing / Nursing Moms

Nursing a baby / toddler on my side has been so hard on my neck and shoulder because I never had proper support. I feel like this pillow saved my life! I wish I'd found it sooner. It's made it sustainable to continue nursing. I am going to send it as a baby shower gift to my friends from now on. Just try it. If it works for you, it's well worth the money. If it doesn't, just return 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.

GET THE SIDE CUBE

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.
