Frequently Asked Questions

How is the Ergo Curve different from the Sacro-Ease Premium?

The Ergo Curve is a lumbar-only cushion with a reversible weighted strap — no seat component, no steel frame. It's the most affordable and portable option in the SacroEase lineup, ideal for users who need simple, effective lumbar support for any chair. The Sacro-Ease Premium features an adjustable steel frame for users who need more customized, structural support.

Is the Ergo Curve good for lower back pain?

Yes. The contoured memory foam supports the natural lumbar curve, reducing muscle fatigue and pressure on the lower back during prolonged sitting. It is a strong first intervention for users with mild to moderate lower back pain from inadequate chair support.

Can I use the Ergo Curve for herniated discs or sciatica?

The Ergo Curve can help by maintaining the lumbar curve and reducing disc compression from poor seated posture. For more severe conditions, we recommend consulting our certified ergonomic specialists to determine if a more supportive product like the Sacro-Ease Premium or Sacro Wedge is more appropriate.

What does the reversible weighted strap do?

The reversible weighted strap lets you position the cushion for either upper or lower lumbar support. Flip the strap to the top for upper lumbar coverage, or to the bottom for lower lumbar support. The weighted design keeps the cushion securely in place without slipping.

What chairs is the Ergo Curve compatible with?

The Ergo Curve works with virtually any chair that has a backrest — office chairs, car seats, dining chairs, wheelchairs, airplane seats, and more. No installation required; simply hang and adjust.

Is the Ergo Curve good for travel?

Yes. The Ergo Curve is lightweight with a built-in carry handle, making it easy to take on planes, trains, or road trips. It's one of the most portable lumbar supports in the SacroEase lineup.

How does the Ergo Curve compare to the Sacro Wedge or Sacro Deluxe?

The Ergo Curve is a lumbar-only cushion without a seat component or steel frame, making it the most affordable and portable option. The Sacro Wedge adds a 2-inch seat wedge for pelvic tilt correction, and the Sacro Deluxe adds a coccyx cutout for tailbone relief. Our specialists can help you choose the right model — schedule a consultation here.

What warranty does the Ergo Curve come with?

The Ergo Curve comes with a 5-year limited warranty — significantly longer than most lumbar cushions on the market.

Is the Ergo Curve made in the USA?

Yes. The McCarty's SacroEase Ergo Curve is manufactured in the USA with premium materials including automotive-grade woven fabric.

How do I set up the Ergo Curve?

Simply hang the Ergo Curve on your seat back using the weighted strap, position it at your lumbar curve (typically at belt level), and flip the strap to the top or bottom depending on whether you need upper or lower lumbar support. No tools or installation required.
