The Side Cube Riser Deluxe is our most spacious adjustable-height pillow, built specifically for side sleepers who want more room to move. The same cube-shaped, modular design that fills the 90° gap between shoulder and head - now in a larger format that gives your head and neck extra real estate for a more comfortable, cradled sleep. Customize your height with removable 1" layers to find your perfect fit at 3", 4", or 5".

• Purpose-built shape, bigger footprint: The same 90-degree gap-filling design side sleepers love, now 35% bigger for more surface area and freedom of movement through the night.
• Adjustable height: Two removable 1" base layers let you dial in your perfect loft - 3", 4", or 5" - so you get proper spinal alignment no matter your shoulder width or mattress firmness.
• Premium foam core: Supportive memory foam that holds its shape night after night for consistent comfort and alignment.
• Lightweight pillow scrim: A smooth, breathable layer that protects the foam without adding bulk or trapping heat - pair it with your favorite pillowcase for a personalized sleep setup.
• Comfort where it matters: Designed to cradle your head and neck in the ideal position for side sleeping - no awkward pressure points.
• Dimensions & weight: Measures 14" W × 28" L × 5" H (fully stacked). Length sized for queen & king beds, and weighs approximately 2.5lbs
• Fast recovery & setup: Ships compressed - allow 24–48 hours for full expansion; do not wash the foam core.

The Side Cube Riser Deluxe height can be adjusted to 3", 4", or 5" to fit most adults.
