The Side Cube Riser is a patent-pending modular pillow engineered for side sleepers who need a personalized fit - not a one-size-guess. Built on the same cube shape that fills the 90-degree gap between shoulder and head, it ships fully stacked at 5" - the height that works for most people right out of the box. If you need less, simply remove one or both included risers to step down to 4" or 3". One pillow, your perfect height.

Patent-pending modular design: Ships fully stacked at 5" — the right height for most side sleepers. Includes two removable 1" risers so you can step down to 4" or 3" if needed.
Purpose-built cube shape: Fills the shoulder gap and cradles the head to support neutral neck and spine alignment, reducing pressure on the neck and shoulders.
Premium AeroFoam core: Breathable viscoelastic polyurethane foam that allows consistent support while resisting heat buildup.
Soft, breathable cover: Ventilated outer shell pulls heat away from the face and neck; removable and machine washable for easy care.
Dimensions & weight: 12" W × 24" L × 5" H (fully stacked); approximately 2.5 lbs. Length sized for twin & full beds.
HSA/FSA eligible: Select Flex | Pay with HSA/FSA at checkout and follow the brief eligibility steps during payment.

The Side Cube Riser ships fully stacked at 5" — the height that fits most side sleepers right out of the box. If it feels too tall, simply remove one or both risers to drop down to 4" or 3".

The Side Cube Riser is backed by a 60-night exchange/refund window so you have time to find your perfect height.

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.

BEST PILLOW EVER
I’ve had neck issues for YEARS, I’ve tried so many pillows and none of them work. I saw a TikTok about this pillow and tried to look for more reviews, but to be honest, there aren’t many reviews online about this product, so I took a chance on it because I was desperate for good sleep and comfort. I am OBSESSED and soooo happy! This product needs all the hype because it’s amazing. I’m so happy to have found this pillow.

Can pillows be life-changing?
Per my doctor’s direction, I’m trying to become a side sleeper, and I was HATING it. I found it so uncomfortable. Then a Reddit deep-dive introduced me to the Pillow Cube. By far the most comfortable pillow I’ve ever tried AND perfect for side sleeping. I’m totally converted!
