Comfort you can see.
EvenSit™ pressure-distribution seat technology uses a responsive honeycomb mesh layer 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.
Real comfort is engineered into the seat—not added as an afterthought.
EvenSit™ changes the structure underneath the fabric. Our proprietary three-layer design combines soft initial cushioning with adaptive support and a responsive honeycomb mesh pressure-relief layer.
What changes beneath the fabric?
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.

Layers that work together
EvenSit™ combines cushioning, adaptive support and a honeycomb mesh structure with a mechanism shell that flexes with movement, helping spread load more evenly and create airflow beneath the user.
Three layers. One responsive seat.
The seat is designed as a system. Each layer has a distinct job, so comfort, support, resilience and airflow work together rather than relying on one block of foam.
Comfort layer
Provides soft initial cushioning when the user first sits down.
Adaptive support layer
Responds to sitting position and absorbs changing loads as the user moves.
Honeycomb mesh layer
Spreads pressure, recovers its shape and creates open channels for airflow.
A more considered kind of comfort—for people and places.
More even pressure
Helps disperse load across the seat rather than concentrating it at a few points.
Natural movement
Responsive layers adapt as the user changes position throughout the day.
Resilient support
The honeycomb structure is designed to return to shape after compression.
Built-in airflow
Open channels through the seat structure encourage air to move beneath the upholstery.
A hidden difference you can feel—and understand.
The Everything Chair brings EvenSit™ pressure-distribution technology into a complete commercial ergonomic chair. The ball demonstration offers a clear view of the responsive seat structure and helps explain why the chair feels different.
EvenSit™ is available exclusively from JH Chairs.
