Eliminate Sciatic Nerve & Back Pain on Your Herman Miller Aeron

If you're experiencing sciatic nerve pain, tailbone discomfort, or lower back pain while sitting in your Herman Miller Aeron chair, the Stratta Seat Cushion solves the problem without sacrificing the chair's ergonomic design. This precision-engineered BioFlex™ foam cushion adds targeted pressure relief exactly where you need it—eliminating pain points while maintaining the Aeron's breathability and postural support.

Who This Cushion Is For

The Stratta Aeron Seat Cushion is specifically designed for professionals experiencing pain in their Herman Miller Aeron chair:

• Sciatic nerve pain, numbness, or tingling radiating down the leg
• Tailbone (coccyx) pain or bruising from prolonged sitting
• Lower back pain or lumbar discomfort during 6+ hour workdays
• Pressure points or "hot spots" on sit bones (ischial tuberosities)
• Post-injury or post-surgical recovery requiring extra cushioning
• Thin or petite users who need additional padding on the Aeron's mesh seat

Ideal for executives, programmers, designers, traders, and remote workers who spend 8+ hours daily in their Aeron and refuse to compromise on comfort or performance.

Why the Stratta Design Works Ergonomically

Precision-Fit Engineering: Unlike generic seat cushions that slide, bunch, or interfere with chair mechanics, the Stratta is laser-cut to match the exact contours of the Aeron Size B and C seat pan. It integrates seamlessly with the chair's PostureFit SL and tilt mechanisms.

BioFlex™ Pressure-Relief Foam: Medical-grade viscoelastic foam distributes your body weight evenly across the seat surface, reducing pressure on the sciatic nerve, tailbone, and sit bones by up to 40% compared to sitting directly on mesh.

Breathable Open-Cell Structure: Maintains the Aeron's signature airflow and temperature regulation. The open-cell foam allows heat and moisture to dissipate, preventing the "swamp seat" effect common with solid foam cushions.

Ergonomic Contour Design: Subtle contouring supports the natural curve of your pelvis and thighs, promoting neutral spine alignment and reducing forward pelvic tilt—a common cause of lower back pain.

Non-Slip Silicone Backing: Stays securely in place on the Aeron's Pellicle mesh without adhesives, straps, or clips. Installs in 10 seconds, removes instantly for cleaning.

Compatibility & Fit Notes

Aeron Size Identification: Check the size label under your seat pan (B = Medium, C = Large). If you have Size A (Small), this cushion will not fit—contact us for alternative solutions.

Aeron Generation Compatibility: Fits both Classic Aeron (pre-2016) and Remastered Aeron (2016+). The seat pan geometry is identical across generations.

PostureFit vs. Lumbar Support: Works with both PostureFit SL (Remastered) and adjustable lumbar support (Classic). Does not interfere with tilt, recline, or seat height mechanisms.

Weight Capacity: Supports users up to 350 lbs without compression or deformation.

Adaptation Period: Most users experience immediate pain relief. Allow 2-3 days for your body to adjust to the new sitting surface and pressure distribution.

Installation & Care

Installation (10 seconds): Center the cushion on the Aeron seat pan with the wider end toward the backrest. Slip the front pocket over the front of the seat pan and secure the Velcro straps. 

Cleaning: Spot clean with mild soap and lukewarm water. Air dry completely before reinstalling (4-6 hours). Do not machine wash or use harsh chemicals.

Storage: If not in use, store flat in a cool, dry place away from direct sunlight to maintain foam integrity.

Frequently Asked Questions

Will this cushion eliminate my sciatic nerve pain?
The Stratta cushion reduces sciatic nerve compression by redistributing pressure away from the piriformis muscle and sciatic nerve pathway. Most users experience 60-80% pain reduction within 1-2 weeks. For comprehensive relief, we recommend pairing with a professional ergonomic assessment to address monitor height, keyboard position, and sitting posture—all of which contribute to sciatic pain.

Does this cushion make the Aeron seat too high?
At 1.5" thickness, the Stratta adds minimal height. If you're already sitting at maximum seat height, you may need to lower your desk or add a footrest. Our workstation optimization service ensures proper desk-to-seat-to-floor ratios after cushion installation.

Will the cushion interfere with the Aeron's tilt or recline?
No. The Stratta is designed to move with the seat pan during tilt and recline. The lightweight foam (11 oz) does not affect tilt tension or require adjustment to your existing settings.

How is this different from a generic seat cushion?
Generic cushions are designed for flat office chairs and slide around on the Aeron's mesh, bunch up during recline, and block airflow. The Stratta is laser-cut to the exact Aeron B/C geometry, features medical-grade silicone grip backing, and uses breathable open-cell foam that maintains the chair's temperature regulation.

Can I use this cushion on other chairs?
The Stratta is precision-engineered exclusively for Herman Miller Aeron Size B and C. It will not fit properly on other chair models. For cushion solutions for other ergonomic chairs, contact our team for recommendations.

What if I have an Aeron Size A (Small)?
The Stratta is not available for Size A due to the smaller seat pan geometry. We recommend a professional chair fitting consultation to explore alternative solutions including lumbar adjustment, armrest positioning, or a different chair model better suited to smaller frames.

How long does the cushion last?
With normal use (40 hours/week), the BioFlex™ foam maintains its shape and pressure-relief properties for 3-5 years. The cushion is covered by a 1-year manufacturer warranty against defects.

Is the foam safe and non-toxic?
Yes. The BioFlex™ foam is CertiPUR-US® certified, meaning it's made without ozone depleters, PBDE flame retardants, mercury, lead, formaldehyde, or phthalates. It's safe for extended daily contact and meets strict indoor air quality standards.

Can I return the cushion if it doesn't relieve my pain?
Yes. We offer a 30-day satisfaction guarantee. If the Stratta doesn't provide the pain relief you need, return it for a full refund. Our ergonomics team will work with you to identify alternative solutions—whether that's a different cushion, chair adjustment, or complete seating upgrade.

Do you offer installation or fitting services?
While the Stratta installs in seconds, we offer complimentary virtual guidance to ensure optimal positioning and chair adjustment. For comprehensive workstation optimization including chair fitting, desk height, monitor placement, and accessory recommendations, schedule an on-site ergonomic evaluation.
