VIA Seating 4-UP Ergonomic Task Stool

Discover 4-UP, the true sit-to-stand experience with dynamic, telescoping gaslift. Unlike solutions before only allowing a user to sit or perch, this revolutionary seat allows users to tap into the full functionally of their sit-to-stand desk. With 4-UP, a person can sit, stand & access every position in between. Combined with seat depth adjustment, ergonomic forward tilt & Via Seating’s proprietary injection-molded comfort foam, it is no wonder 4-UP was the first ever Best of NeoCon Business Impact award winner for an ergonomic desk chair. All 4-UP 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. Comfort Foam Available in Mesh Back or Upholstered Back model.
