How we reached each verdictThe numbers behind each model's score
Autonomous ErgoChair Pro
All 4 expert reviews are hands-on and positive (expert score 84), with every one praising comfort and back or lumbar support, and reviewed.com naming it best overall. Owners are cooler at a score of 66: of 83 comments (60 first-hand), 20% praise comfort and 16% back support, but 15% mention a failure, 7% say it broke, and 7% each complain about customer support or value. Reliability scores just 62, and plastic construction plus quality-control slips (a faulty armrest nut and a loose lumbar cushion) come up in expert testing too. Confidence is low: only 3 published scores and no retail ratings, so long-term durability evidence is thin.
Herman Miller Sayl
Four of 5 expert sources tested the Sayl hands-on, and all four call it comfortable and well built; Forbes named it its best office chair overall after a month of panel testing. Owners agree: of 534 comments (477 first-hand), 53% praise comfort and 21% specifically praise back support, while only 3% mention back pain and 7% mention any failure. About 80% of the 1,306 star ratings we saw are five stars. The evidence is thinner on back problems specifically, since no expert evaluated it for medical back conditions, Consumer Reports' results are paywalled, and lumbar support depends on an extra-cost option that testers judged differently.
Where each one falls shortThe most common complaints
Autonomous ErgoChair Pro
- Mostly plastic build, with some owners reporting breakage

- Thin seat padding for some, plus mixed customer support
Herman Miller Sayl
- Short backrest and no headrest for tall users
- Lumbar support and other add-ons cost extra, and some find the lumbar flimsy
- Armrest adjustment and seat padding wear draw some complaints
