McCarty's Sacro Wedge Lumbar Support System The McCarty's Sacro Wedge is a complete seated ergonomic system that addresses lower back pain from two directions at once. The adjustable steel frame lumbar support maintains your natural lumbar curve from behind, while the included 2-inch seat wedge tilts your pelvis forward to restore proper spinal alignment from below. Together, they create a comprehensive solution that no single lumbar cushion can match. Doctor-designed and trusted by Ask Ergo Works' certified ergonomic specialists for over 30 years, the Sacro Wedge is our premium recommendation for professionals with chronic lower back pain, poor posture, sciatica, or disc issues who spend extended hours seated.

It tilts your pelvis forward, naturally restoring your lumbar curve and reducing the effort needed to sit upright. Step 2 — Lumbar Support: Attach the adjustable steel frame back support to your seat back. Bend the frame to match your lumbar curve and position it at your lower back. Result: Your spine is supported from both the seat and the back, maintaining proper alignment with minimal muscular effort throughout the day. Frequently Asked Questions What makes the Sacro Wedge different from other lumbar supports? The Sacro Wedge is a two-part system: an adjustable steel frame lumbar support for the back combined with a 2-inch seat wedge that tilts the pelvis forward. This dual approach addresses both lumbar support and pelvic positioning simultaneously, making it more comprehensive than a lumbar cushion alone. What is the difference between the MSE4 and MSE6? The MSE4 is the standard Sacro Wedge with a regular back height, while the MSE6 features a taller 24-inch back panel for users who need support higher up the spine. The MSE6 is ideal for taller individuals or those with upper lumbar or mid-back discomfort in addition to lower back pain. Is the Sacro Wedge good for herniated discs or sciatica? Yes. The combination of lumbar support and anterior pelvic tilt from the seat wedge reduces disc compression and nerve irritation associated with herniated discs and sciatica. We recommend consulting your healthcare provider or one of our certified ergonomic specialists for active diagnoses. Can I use the Sacro Wedge for post-surgical recovery? Many patients recovering from lumbar or hip surgery use the Sacro Wedge to maintain proper spinal alignment during recovery. Please consult your surgeon or physical therapist to confirm suitability for your specific situation. How does the 2-inch seat wedge help with posture? The 2-inch seat wedge creates an anterior pelvic tilt, which naturally restores the lumbar curve and reduces the tendency to slouch. When combined with the lumbar back support, it creates a complete seated ergonomic system that maintains proper spinal alignment with minimal effort. What chairs is the Sacro Wedge compatible with? The Sacro Wedge works with most standard office chairs, task chairs, car seats, and home seating. The adjustable steel frame and elastic straps fit a wide range of seat backs. How does the Sacro Wedge compare to the Sacro-Ease® Premium? The Sacro-Ease® Premium provides lumbar back support only, while the Sacro Wedge adds a 2-inch seat wedge for pelvic tilt correction. If you need both lumbar support and posture correction from the seat up, the Sacro Wedge is the more comprehensive solution. How does the Sacro Wedge compare to the MSE3 Sacro Deluxe? The MSE3 Sacro Deluxe is a single-piece lumbar support with a coccyx cutout for tailbone relief. The Sacro Wedge is a two-part system that adds a seat wedge for pelvic tilt correction — the better choice when posture correction from the seat up is the priority. Can I use the Sacro Wedge in my car? Yes. The Sacro Wedge is portable and works well in car seats, making it a popular choice for commuters and long-distance drivers who experience lower back pain during driving. Is the Sacro Wedge made in the USA? Yes. McCarty's Sacro Wedge is manufactured in the USA with premium materials and has been doctor-designed and trusted by ergonomic specialists for over 30 years. How do I know if the MSE4 or MSE6 is right for me? If you primarily experience lower back pain, the MSE4 standard height is typically sufficient. If you are tall or experience discomfort higher up the back, the MSE6 with its 24-inch back panel provides additional coverage.
