Does a sit-stand desk require a special chair?

No special chair is required. Any standard commercial task chair works with a sit-stand desk. Some users benefit from a saddle stool or sit-stand stool that allows a semi-standing posture at an intermediate height — reducing lower back fatigue during transitions. Sit-stand stools are not a replacement for a full ergonomic chair; they are supplementary. At OfficeFurniture2go.com, we carry both task chairs and sit-stand stools — call 1-800-460-0858.
