Fabric over a CMHR foam cushion
A conventional upholstered task-chair seat commonly uses a CMHR foam cushion over a rigid plywood base. As the foam compresses, support may become more concentrated around the main contact points.
EvenSit™ · Exclusive to JH Chairs
Comfort you can see.
EvenSit™ pressure-distribution seat technology uses a flexible seat shell and pressure-distribution structure beneath the upholstery to spread load more evenly, support natural movement and help reduce pressure points during extended sitting.
The ball demonstration offers a simple look at the hidden seat structure.
