4up Sit-to-Stand Office Chair

Based on Via’s original 4u design, the 4up features an innovative telescoping gas lift that takes the chair from a true desk height position all the way to any position your lift desk can reach

  • The sit-to-stand function of 4up is not a simple ‘drafting stool’ attachment. With this version, you can still use the chair at your standard desk height. As you raise the seat, the foot ring becomes your ‘floor’ for support. You can sit or perch as you get higher, maintaining a neutral spine position all the while.
  • Choose one of three back styles: mesh, groove, or upholstered with any current commercially graded fabric or leather cover for the seat. Upholstered version can be ordered with all-over single cover or two-toned (seat & back)
  • Frame is available in black or white with matching 5-star base; stool footrest standard in polished chrome
  • Choose between black carpet casters or grey/black all floor casters
  • Optional arm kit, advanced synchro, forward tilt, and telescoping gas lift complete the features.
  • Visit Via’s “spec-it” page to custom design a 4up chair to your liking. LaDIFF’s price is 20% off Via’s MSRP.
