The short answer: buy the Steelcase Series 1 if you weigh over 275 lb, want 4D arms, or want a chair you’ll keep for a decade. Buy the Branch Ergonomic Chair if you want the lowest price and a softer, more cushioned seat, or step up to the Branch Ergonomic Chair Pro if you want more adjustment for $499. Both are mesh-back task chairs with adjustable seat depth and lumbar support, built for a home office.
Prices in November 2026: the Branch Ergonomic Chair is about $359 on Amazon (sold by Branch) and $369 to $389 on Branch’s site. The Steelcase Series 1 is about $494 on Amazon from Pattern, Steelcase’s authorized Amazon seller, and $525 (was $584) in Steelcase’s own holiday sale through December 8, 2026.
One more thing to know before buying a Branch: the standard Branch Ergonomic Chair was recalled on September 3, 2026, because its backrest can detach. Chairs made from September 10, 2025 to April 22, 2026 are affected, and the fix is a free repair kit. Details are below.

Weight Capacity: The Biggest Difference
Steelcase rates the Series 1 to 400 lb, the same as its Leap and Gesture. Branch rates its Ergonomic Chair, and the Pro, to 275 lb. If you’re anywhere near 275 lb, the Series 1 has far more margin. Our guide to office chair weight limits explains what those ratings mean.
Recline and Adjustment
The two chairs handle recline differently. The Branch uses a conventional synchro-tilt with a tension knob, so you set how hard the back pushes against you.
The Series 1 has no tension knob. Its weight-activated mechanism sets the resistance from your body weight, and a three-position comfort dial switches between an upright lock, a “boost” setting with extra tension, and free recline. That’s simpler to live with, but you can’t fine-tune it if the automatic tension feels too loose or too stiff.
The Series 1’s 4D arms move up, down, in, out, forward, back and pivot. The Branch’s arms move in three directions. If you type with your forearms on the armrests, the Series 1 gets them closer to your keyboard.
Seat and Back
The Branch has a mesh back and a thick padded seat. The Series 1 has a 3D Microknit back over flexible plastic “LiveBack” fingers that move with your spine, and a foam seat with flexible edges. Its seat goes slightly lower, to 16.5 inches, and slightly higher, to 21.5. See office chair seat height ranges for how both compare with other chairs.
Both have height-adjustable lumbar support. On the Series 1, adjustable lumbar is standard on the 3D Microknit back. The Branch’s lumbar pad can also be removed entirely.
The Branch Ergonomic Chair Recall
On September 3, 2026, Branch and the CPSC recalled about 16,000 Branch Ergonomic Chairs in the US (recall number 26-735), plus about 180 in Canada:
- Hazard: the backrest can detach if its anchors weren’t installed correctly. Branch had 11 reports of backrests detaching and no injuries.
- Affected chairs: the standard Ergonomic Chair only, in all eight colorways, made in Thailand from September 10, 2025 to April 22, 2026. SKUs start with 11-01-00. The manufacture date is on the label under the seat cushion. The Ergonomic Chair Pro is not included.
- Where sold: Branch, Amazon, West Elm, The Container Store, Office Depot and other sites, about December 2025 to July 2026, for $320 to $350.
- Remedy: stop using the chair and get a free repair kit with a replacement backrest, three bolts and an Allen key from branchfurniture.com/recall. Branch doesn’t offer refunds or replacement chairs under the recall.
Chairs sold new now are outside the affected date range. Our list of office chair recalls covers this and other recent recalls.
Warranty
Steelcase’s consumer warranty covers the Series 1’s frame and structure for life, and its mechanism, cylinder, foam, arm caps and casters for 12 years, regardless of how many hours a day it’s used. It covers the original buyer from Steelcase or an authorized reseller, which on Amazon means Pattern-sold listings.
Branch covers parts and components for 7 years for the original buyer from Branch or an authorized reseller, in the continental US and Canada. Our office chair warranty comparison has the details for more brands.
Which Should You Buy?
| If you… | Better pick | Why |
|---|---|---|
| Weigh over 275 lb | Series 1 | Rated to 400 lb |
| Want the lowest price | Branch Ergonomic Chair | About $135 less |
| Rest your forearms on the armrests while typing | Series 1 | 4D arms |
| Like to set your own recline tension | Branch | Tension knob instead of a weight-activated mechanism |
| Want a softer, padded seat | Branch | Thicker cushion |
| Want the longest warranty | Series 1 | Lifetime frame, 12-year parts |
| Want more adjustment and can spend $499 | Branch Ergonomic Chair Pro | 5D arms, lumbar depth, forward tilt, not part of the recall |
For most people, the Series 1 is the better buy at about $494 on Amazon: it’s rated to 400 lb, has better arms and a far longer warranty for about $135 more. The Branch makes sense if price is the deciding factor or you prefer a cushioned seat. If you want the most adjustment for under $500, compare the Series 1 with the Branch Ergonomic Chair Pro and the HON Ignition 2.0.
