How to choose a right ergonomic office chair?
Check out our buying guide for you!
What is DynaCore™ Full-Body Support?
DynaCore™ connects the headrest, backrest, lumbar support, and armrests so they move together as you change positions. This helps keep support with you whether you're sitting upright, shifting, or reclining.
How does the SyncroFlex™ Back-Glide work?
SyncroFlex™ lets the backrest glide with your back as you lean and recline. Its dual-track, dual-spring design helps maintain comfortable contact with your back as your position changes.
What height range is the C300 Pro V2 designed for?
The C300 Pro V2 is designed to comfortably fit users from 4'11" to 6'3" (150–190 cm), with adjustable backrest height, seat depth, headrest, armrests, and lumbar support to help you fine-tune the fit.
Who is the C300 Pro V2 best for?
It's a great fit for anyone who spends a lot of time sitting—whether you're working, creating, gaming, or simply relaxing at your desk. Its adjustable, full-body support makes it easy to find a setup that feels right for you.
What does the 3-year warranty cover?
The C300 Pro V2 comes with a 3-year warranty covering manufacturing defects. If a covered issue occurs, we'll provide replacement parts at no additional cost. Normal wear and tear and damage caused by misuse are not covered.
Is there a best office chair for neck and shoulder pain?
The best office chair for neck and shoulder pain depends on fit and the cause of your discomfort. If you are searching for the best office chair for neck and shoulder pain, compare the headrest, armrest, and backrest adjustments with your posture. A chair cannot diagnose or treat pain; seek medical advice if symptoms persist.
