Sleep aid designed to reduce hip, knee and sciatica discomfort for side sleepers. The CAIFU Knee Pillow promises more restful, less painful mornings for pregnant people and anyone with leg or joint pain. Is it robust enough for nightly use and simple to care for over time?
⚡ At a Glance
- • Wearing Comfort: Ergonomic crescent shape keeps legs aligned while reducing pressure points
- • Best for: Side sleepers, expectant parents and people recovering from leg or knee issues
- • Not ideal for: Back sleepers who need full lumbar support rather than knee separation
Orthopaedic contour separates knees to align hips and spine. Premium memory foam maintains shape for consistent support.
Reduced back and hip pain - with 100% premium memory foam
Made from 100% premium quality memory foam, pure with no additives, the foam contours slowly to body shape to distribute pressure evenly across the knees and hips. High-density construction resists flattening so cushioning remains consistent over time.
Even pressure distribution and sustained loft keeps legs properly spaced, reducing morning discomfort in the lower back and hips.
Secure alignment through the night - with adjustable elastic hook-and-loop strap
An elastic strap with hook-and-loop fastening attaches around the thighs and is adjustable to fit a range of sizes, approximately 16 to 25 inches. The strap limits lateral movement so the knee spacer stays in place while turning.
Maintained alignment reduces the need to reposition overnight, making support more reliable for restless sleepers.
Cooler, cleaner sleep surface - with breathable, machine-washable zippered cover
The cover uses an air layer fabric and an intermediate hollowed-out design that increases airflow across the surface, and a zipper allows removal for machine washing. Breathable materials reduce heat build-up against the skin.
Greater airflow helps prevent overheating and a removable cover makes hygiene easy to maintain.
