Seat Styles

All 4u seats use Via Seating’s comfort foam. This is a proprietary blend of high-density, injection-molded, closed-cell, cold-cured comfort foam  so durable and lasting it is backed by Via Seating’s 12 year warranty. Unlike traditional stacked foam pieces, Via’s seats are contoured to maximize comfort and support where needed with a circulation supportive waterfall edge.

 

Note: Dimensions for each seat size are width x depth of the seat measured off the chair. See the Dimensions tab above for exact seat dimensions for each configuration.
