4-UP | Via Seating

Discover 4-UP, the true sit-to-stand experience with dynamic, telescoping gaslift.

With 4-UP, a person can sit, stand & access every position in between. Combined with a 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.
