About

Description

Love Your Aeron Again — Without the Pain

Fix the hard front edge that causes thigh pressure, numbness, and sciatic discomfort. Finally sit comfortably in your Aeron — without replacing it.

✅ Designed specifically to relieve pressure from the Aeron's rigid front edge

✅ Supports better circulation and reduces nerve compression

✅ Installs in seconds — no tools required


Why Your Aeron Chair Might Be Causing Pain

The Herman Miller Aeron Chair is one of the most iconic ergonomic chairs ever made — but it's not perfect for everyone. Many users experience:

  • Pressure under the thighs from the rigid front frame
  • Reduced circulation in the legs
  • Tingling or numbness after sitting
  • Sciatic nerve discomfort

The issue isn't the chair — it's the edge support design.


A Simple Fix That Makes a Big Difference

The Stratta Aeron Seat Cushion is engineered to:

  • Redistribute weight away from pressure points
  • Soften the front edge without compromising support
  • Enhance comfort instantly — no need to replace your chair

Think of it as the missing comfort layer your Aeron never had.


Before vs. After

Without Cushion With Stratta Aeron Cushion
Hard edge presses into thighs Even pressure distribution
Circulation may be restricted Improved comfort and posture
Discomfort builds throughout the day Sit longer without pain or distraction

Who This Is For

  • Your Aeron feels uncomfortable after extended sitting
  • You feel pressure under your thighs
  • You experience numbness or sciatic discomfort
  • You don't want to replace a premium chair

Features & Benefits

  • Targeted Pressure Relief — Designed specifically for the Aeron's unique seat structure
  • Maintains Ergonomic Support — Doesn't flatten posture like generic cushions
  • Breathable Mesh Design — Keeps airflow similar to the original Aeron seat
  • Quick & Easy Setup — Installs in seconds, no tools or modifications

What Customers Are Saying

★★★★★ “The front edge was killing my legs. This completely solved it. I can finally sit all day again.” — Verified Buyer

★★★★★ “Didn't expect much — but within minutes I felt the relief. Huge difference immediately.” — Verified Buyer


Why Not Just Buy a New Chair?

Because you don't need to. Replacing your Aeron could cost $1,000+. The Stratta cushion solves the specific issue — for a fraction of the cost.


Which Size Do I Have? Aeron Size Guide

Herman Miller Aeron chairs come in three sizes: A (Small), B (Medium), and C (Large). Here's how to identify yours:

Method 1 — Look for Dot Markers

Turn the chair around and look under the top edge of the back frame. You'll find raised dot markers molded into the frame:

● = Size A (Small) → Order Size B Cushion

●● = Size B (Medium) → Order Size B Cushion

●●● = Size C (Large) → Order Size C Cushion

Method 2 — Check the Label

Flip up the seat or look underneath the chair. A label on the seat pan or frame will show the size: A, B, or C. Some labels also show the full model number (e.g., AE113 = Size A, AE223 = Size B, AE333 = Size C).

Method 3 — Measure the Seat Width

Aeron Size Seat Width Best For
Size A (Small) ~15.75 in (40 cm) Smaller frames, under ~130 lbs
Size B (Medium) ~17.75 in (45 cm) Most users, 130–230 lbs
Size C (Large) ~20 in (51 cm) Larger frames, 230+ lbs

Which Stratta Cushion Should I Order?

  • Size A or B Aeron? → Order the Size B Stratta Cushion
  • Size C Aeron? → Order the Size C Stratta Cushion

Frequently Asked Questions

Does this work with all Aeron sizes?

Yes — the Stratta cushion is available in Size B (fits Aeron A & B chairs) and Size C (fits Aeron C chairs). Use the size guide above to confirm which to order.

Will it affect my posture or ergonomic support?

No — the Stratta is specifically engineered to enhance comfort without flattening your posture or undermining the Aeron's ergonomic design. Generic cushions often raise seat height and tilt the pelvis; the Stratta avoids this.

Is it easy to install and remove?

Yes — no tools required. Simply place and adjust. It's fully removable and portable, so you can take it between home and office if needed.

Does it work with both Classic and Remastered Aeron models?

Yes. The Stratta cushion is compatible with both the original Classic Aeron and the Remastered Aeron in the corresponding size (B or C).

Will this help with sciatic nerve pain specifically?

Yes. The Stratta redistributes pressure away from the front edge of the seat, which is a common trigger for sciatic nerve compression during prolonged sitting. Many users report significant reduction in sciatic discomfort within the first session.

How does this compare to a generic seat cushion?

Generic cushions are designed for flat seat pans and don't account for the Aeron's unique mesh and frame geometry. The Stratta is purpose-built for the Aeron's specific structure, providing targeted relief without compromising the chair's original ergonomic intent.

Is this suitable for corporate Aeron fleet deployments?

Yes — many corporate ergonomics programs and facilities teams use the Stratta as a cost-effective solution for employees experiencing Aeron discomfort, avoiding the need to replace or upgrade chairs. For bulk orders or ergonomic assessments, contact our certified specialists.

What if it doesn't work for me?

If you're unsure whether the Stratta is the right solution for your specific pain pattern, our ergonomic consulting services can assess your seating setup and recommend the most effective intervention before you purchase.

Still experiencing discomfort even with the Stratta?

If the cushion alone doesn't fully resolve your discomfort, the root cause may be a broader workstation setup issue — monitor height, keyboard position, or chair height. Our certified ergonomic specialists offer professional workstation evaluations to identify and fix the full picture. You may also want to explore our Professional Ergonomic Workstation Evaluation service.


Complete Your Ergonomic Setup

The Stratta cushion solves the Aeron's edge pressure problem — but optimal comfort often requires a fully configured workstation. Our specialists can help you address monitor height, keyboard positioning, and desk setup as part of a complete ergonomic solution.
