Key Features of the Purple Seat Cushion
GelFlex Grid Technology
The heart of every Purple Seat Cushion is the proprietary GelFlex Grid technology. This hyperelastic polymer is arranged in a grid pattern that flexes under pressure points while providing support where needed. Unlike memory foam that can trap heat, the grid design allows for constant airflow, keeping you cool even during extended sitting sessions.

Dual-Layer Design (Double Seat Cushion)
The Double Seat Cushion features two different grid layers: a smaller grid on one side for softer seats and a larger grid on the other for harder surfaces. This versatility makes it ideal for use across different chairs and seating situations.
Removable, Washable Cover
All Purple seat cushions come with a removable, machine-washable cover with a non-slip bottom to keep the cushion securely in place. The cover is designed to maximize airflow while protecting the cushion from dirt and spills.
Portability Features
Most models include a built-in carrying handle, making them easy to transport between home, office, car, or events. The Foldaway model can be folded in half for even more convenient storage and transport.

Long-Term Testing: How Does the Purple Seat Cushion Hold Up?
I’ve been using the Purple Royal Seat Cushion daily for over two years, and I’m impressed with how well it has maintained its shape and support. Unlike memory foam cushions that tend to flatten over time, the GelFlex Grid technology has proven remarkably resilient.
After approximately 2,000 hours of sitting, the cushion shows minimal signs of wear. The grid structure remains responsive, providing the same level of comfort and pressure relief as when it was new. The cover has held up well to multiple washings, though the zipper has become slightly less smooth in operation.

One of the most impressive aspects is the cushion’s temperature regulation. Even during summer months, the open grid structure prevents heat buildup, a common complaint with solid foam cushions. This breathability factor alone makes the Purple cushion worth considering for anyone who tends to run hot.
Who Needs a Purple Seat Cushion?
Office Workers
If you spend 8+ hours at a desk, the Double or Ultimate Seat Cushion can transform an uncomfortable office chair into an ergonomic throne, potentially improving your productivity and reducing end-of-day discomfort.
People with Tailbone Pain
The grid structure provides excellent pressure relief for the coccyx area, making it ideal for those suffering from tailbone injuries, sciatica, or post-surgery discomfort.

How to Clean Your Purple Seat Cushion
Cleaning the Cover

Cleaning the Grid
