You already know the Side Cube Original works. Now get one for the other side of the bed — and stop waking up in a tug-of-war. The Side Cube Original is a cube-shaped memory foam pillow designed specifically for side sleepers. By filling the 90° gap between shoulder and head, it promotes neutral neck and spine alignment so you wake up with less neck and shoulder pain and improved sleep quality. Now featuring a clean, lightweight pillow scrim in place of our previous quilted cover — giving you the same premium foam core at a better price. The scrim provides a smooth, breathable layer that lets the foam do what it does best without adding bulk or extra heat. Purpose-built shape: Fills the 90-degree shoulder gap to cradle your head and support proper spinal alignment. Premium foam core: Aero foam core which offers supportive, pressure-relieving comfort and breathability. Lightweight pillow scrim: A smooth, breathable layer that protects the foam without trapping heat — pair it with your favorite pillowcase for a personalized sleep setup. Comfort where it matters: Soft middle relieves ear pressure while supporting the head and neck for side sleeping. More pillow, better value: Get the same Side Cube performance at a better value. Dimensions & weight: Standard Side Cube measures 12" W × 24" L × 5" H and weighs approximately 2.5 lb. Fast recovery & setup: Ships compressed — allow 24–48 hours for full expansion; do not wash the foam core. The Side Cube Original comes in standard 5" height that fits most adults. If you sometimes sleep on your back, consider a different model or the Combo Cube for mixed sleepers.
