After a few emails and a couple months, I finally received one of the coolest "upgrades" to my chair to date. I talked the powers to be at Accessible Designs, Inc. (better knows as simply ADI) into putting the unbeatable Supracor honeycomb cushion material in their already killer carbon fiber backrest.
The newest thing to come from the great folks at Supracor is the Stimulite Tension Adjustable Back. Using the same great honeycomb cushion material already in their cushions and heaps of other products, they can now take care even of more of your seating needs.
