Wake up without the tension — your sleeping position matters more than you think.
If you sleep on your side, your knees pressing together and your pelvis twisting puts real strain on your lower back, hips, and lower body — every single night. The SideAlign™ Knee Pillow is designed to gently separate your knees, keeping your spine in natural alignment so you can sleep through the night and wake up feeling refreshed instead of stiff.
Key Benefits:
- ✓ Ergonomic heart-shaped design — cushions between your knees for precise spinal alignment support
- ✓ Memory foam core — adapts to your body contours, maintaining comfortable leg separation all night
- ✓ Designed for side sleepers — helps reduce hip tension, lower back discomfort, and lower-body pressure
- ✓ Available in 3 colours — Blue, Grey, and Pink to suit your preference
- ✓ Machine-washable removable cover — hygienic, soft, and easy to maintain
- ✓ Compact & travel-friendly — lightweight design fits easily in any bag or suitcase
Suitable for left or right side sleeping. Ideal for use at home, during pregnancy, and for post-surgery recovery comfort. Simply slip the pillow between your knees before you sleep — no straps, no fuss, no adjustments needed.

Built for the way you actually live
Designed for Side sleepers seeking ergonomic leg separation to support comfortable spinal positioning during sleep, whether at home, during pregnancy, or post-surgery recovery periods.
How it works
Position Between Knees
Lie on your side and place the wider curved section of the pillow between your knees. The heart-shaped design naturally nestles into position without straps or fasteners.
Memory Foam Adapts
The high-density memory foam core responds to your body heat and weight, conforming to your unique leg contours while maintaining structural support throughout the night.
Maintains Alignment
By keeping your knees separated at an ergonomic distance, the pillow helps support your pelvis and spine in a neutral position — the same posture sleep positioning experts recommend for side sleepers.
What makes this different
Ergonomic Heart Shape
Contoured design specifically engineered for side sleeping — wider top section cushions between knees, tapered bottom prevents pillow from sliding out during sleep
High-Density Memory Foam
Premium foam core (density: 50 kg/m³) provides supportive cushioning that adapts to your body contours without compressing flat or losing shape over time
Machine-Washable Cover
Soft, breathable removable cover (100% polyester) — simply unzip, remove, and machine wash cold; tumble dry low for easy hygiene maintenance
Compact & Travel-Ready
Lightweight 9" × 7.9" × 5.9" dimensions and 0.55 lb weight — fits easily in luggage, briefcase, or tote bag for consistent sleep support wherever you travel
Three Color Options
Choose from Blue, Grey, or Pink cover colors to match your bedroom décor or personal preference — same ergonomic design in every option
No-Fuss Design
No straps, no buckles, no complicated adjustments — simply position between knees and sleep; heart shape naturally stays in place throughout the night
