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™ 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.
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.
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™ 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.
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.
Provides soft initial cushioning when the user first sits down.
Responds to sitting position and absorbs changing loads as the user moves.
Spreads pressure, recovers its shape and creates open channels for airflow.
Helps disperse load across the seat rather than concentrating it at a few points.
Responsive layers adapt as the user changes position throughout the day.
The honeycomb structure is designed to return to shape after compression.
Open channels through the seat structure encourage air to move beneath the upholstery.
The Everything Chair is designed to be refreshed rather than discarded. At the end of its first life, the EvenSit™ seat can be renewed on site to help prepare the chair for a potential further 10-year second life.
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.
