Most chairs in the market are simply designed poorly. Improper concave back shapes giving no thoracic support, very little or too much lumbar support, seat pans that do not adjust, and hard seat cushion foam that quickly causes burning sensations.
Over a decade ago ECD perfected a new seat cushion comprised of soft “Memory Foam” and a high density foam core. This combination gives our Quest, Vive’ and Trudeau series the most comfortable “sit” while stabilizing the pelvic girdle. Our Convex thoracic foam correctly positions the users head over their shoulders and hips.
ECD’s Quest, Vive’ and Trudeau series are standard with thoracic back foam as well as memory foam seats. Thoracic foam is now optional on ECD’s other series. It fits between the user’s shoulder blades and supports the mid to upper back properly.
