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

This is ideal if:

  • ✔ 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."

"Didn't expect much—but within minutes I felt the relief. Huge difference immediately."


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

How to identify your Aeron chair size: 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

This factory identification system is used on both Classic and Remastered Aeron chairs and is the most reliable way to verify your chair size.

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 (approx.) 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 — most common
Size C (Large) ~20 in (51 cm) Larger frames, 230+ lbs

Method 4 — Check Your Purchase Receipt or Herman Miller Account
