Expert-Designed Lumbar-Only Support

Contoured Memory Foam Design

The Ergo Curve features proprietary molded visco-elastic memory foam shaped to support your spine's natural lumbar curve. Unlike flat cushions that compress unevenly, the contoured design maintains consistent support throughout the day, reducing pressure on your lower back and promoting healthy posture. The memory foam conforms to your body while providing the firm support your spine needs.

Reversible Weighted Strap System

The innovative reversible weighted strap gives you complete control over your lumbar support placement. Position the strap at the top for upper lumbar support, or flip it to the bottom for lower lumbar support — whatever your back needs most. The weighted design keeps the cushion securely in place without slipping, while the adjustable strap fits chairs of all sizes. This flexibility makes it easy to find your perfect comfort zone.

Universal Compatibility

Designed as a lumbar-only product, the Ergo Curve is the economical way to add professional-grade back support to any seating environment. Simply hang the cushion on your seat back using the weighted strap and adjust as needed. Works perfectly with office chairs, car seats, dining chairs, kitchen chairs, wheelchairs, airplane seats, and more. No installation required — just hang and adjust.

Portable Professional Support

The built-in carry handle makes it easy to transport your lumbar support wherever you go. Take it from your office chair to your car for the commute home, bring it to meetings, or pack it for travel. Weighing just 6.5 lbs and measuring 14" W × 15" H, it's compact enough to move easily while providing full lumbar coverage.

The Science Behind the Design

Proper lumbar support is essential for maintaining the natural S-curve of your spine during seated work. Without adequate support, your lower back muscles must work constantly to maintain posture, leading to fatigue, pain, and potential long-term issues. The Ergo Curve's contoured memory foam provides the external support your spine needs, allowing your back muscles to relax while maintaining healthy alignment. The reversible strap system ensures you can position the support exactly where your body needs it most.

Versatile Use Anywhere

The Ergo Curve is designed to work with virtually any seat that has a backrest. Use it in your office chair for workday support, move it to your car for commute comfort, hang it on your dining chair for meal times, or pack it for airplane travel. The simple hang-and-adjust design means you can set it up in seconds, and the carry handle makes it easy to take your lumbar support wherever you need it.
