How they differ in real use
Built from our office chairs for lower back pain scoring, each product's published specifications, and verified owner feedback — not hands-on testing.
Both the Steelcase Series 2 and the Autonomous ErgoChair Pro made our Top 5 Office Chairs for Lower Back Pain, at #1 (best overall) and #4. The best balance of low-back support, adjustability, and price for most people. The Series 2 pairs a height-adjustable integrated lumbar — so firm support lands exactly on your low back — with Steelcase's LiveBack backrest that flexes to follow your spine as you move. It brings contract-grade ergonomics, adjustable seat depth, 4-way arms, and a 12-year warranty for roughly a third of the flagship price, which is why it takes the top spot over chairs that cost far more. The most adjustable chair in the mid-range. Its six-inch sliding lumbar lets you place firm support precisely up or down the backrest, and nine points of adjustment — including 4D arms and a headrest — let you tune every contact point. It lands fourth because reviewers consistently rate the adjustability highly but call the seat's out-of-the-box comfort merely good, so it trails the picks above on all-day feel despite its control.
