Sidney Sleep King Shredded Memory Foam Pillow for Side & Back Sleepers — Adjustable Loft, Extra Fill (Blue)

The Sidney Sleep King pillow is an adjustable shredded memory foam pillow designed to let side and back sleepers customize loft and firmness for better neck and shoulder comfort.

Built with removable foam fill and a soft, breathable cover, this king-size pillow (19" x 36") arrives with extra stuffing and a storage bag so you can fine-tune height and support without buying multiple pillows. The plush outer case is machine-washable for easy upkeep, while the shredded memory foam core conforms to your shape and recovers quickly for consistent comfort night after night.

How do I change the pillow’s height and firmness?

Adjusting the Sidney Sleep pillow is simple: unzip the inner casing, remove or add shredded memory foam until the pillow reaches your preferred loft, then store any extra fill in the included bag. Small adjustments let you target the exact neck alignment you want for side or back sleeping positions.

• Open inner zipper to access shredded foam
• Add foam for higher loft or remove for lower profile
• Use included storage bag for excess fill
• Fine-tune in increments for personalized comfort

Will this pillow work for side and back sleepers?

Yes—its customizable fill makes it suitable for both side and back sleepers by letting you increase loft for side support or reduce loft for back alignment. The shredded memory foam fills gaps at the neck and shoulders while remaining breathable and adaptive.

• Higher loft options support side-sleep shoulder spacing
• Lower loft options suit back sleepers who need gentle neck support
• Shredded foam contours without becoming flat or stiff
• King size offers extra surface area for movement

How do I care for the pillow and cover?

The outer plush cover is removable and machine-washable, making routine maintenance quick and straightforward. For the foam core, spot clean only and keep it dry to preserve resilience and longevity.

• Remove and machine-wash the plush cover as needed
• Air-dry cover to maintain softness
• Spot-clean foam; do not machine-wash foam pieces
• Store unused foam in the included bag to protect it

What materials and dimensions should I expect?

The pillow uses premium shredded memory foam inside a soft, breathable fabric case sized 19" x 36" (king). Extra foam fill is included to let you build your ideal loft without additional purchases. Materials are chosen for comfort, airflow, and durability rather than clinical claims.

• King size: 19" x 36"
• Shredded memory foam core for contouring support
• Plush, breathable removable cover for comfort and hygiene
• Included storage bag for excess foam

Who is this for: The Sidney Sleep Adjustable King Pillow is designed for sleepers who value a customizable foundation—especially side and back sleepers who need to change loft or firmness without replacing the entire pillow.
