Are kneeling chairs actually good for your back?

Reviewers we read broadly agree that the forward-tilted seat opens the hips and reduces lumbar compression, which many users say relieves lower-back pain. However, physical therapy and ergonomics community threads consistently warn that kneeling chairs are not designed for all-day use: prolonged sessions tend to shift discomfort to the knees, shins, or neck. The consensus is to treat them as one position in a rotation, not a single all-day chair.
