Here at AD were something of office chair connoisseurs. Weve tested some of the best desk chairs on the market (and others not so great), meaning we know what to look for when it comes to seating that doesnt sacrifice points in the style department.Next up in the hot seat: Branchs Ergonomic Chair Pro, the brands most advanced ergonomic chair yet in a line of sleek, stylish options for the office. The chair is an improvement on Branchs original Ergonomic Chair and is designed to make your work day feel more comfortable with 14 (!) customizable features catered to every and anybody.Perhaps its biggest ace is its thick, cushy seat filled with high-density foam, which is more padded than its original Ergonomic Chair and most other office seating weve tried, period. Here, a handful of our editors spent a workday in the Ergo Chair Pro and are reporting back on exactly how cushy and customizable it is.Branch Ergonomic Chair ProDesignWhile you wont find too many chairs that offer the same designs in both leather and non-leather variations, the Ergo Chair Pro is a notable exception, with nine neutral colorways shared across three different finishesmesh, leather, and vegan leather. Its design is fairly understated and we appreciate that lighter color options, like the creamy shade Shore seen here, are available if your desk or office decor already leans towards a brighter color palette. For traditionalists, the black and dark grey colorways will lend your office a classic, more serious vibe.AdjustabilityPhoto: Audrey LeePoints of adjustability: height adjustable , adjustable armrests , adjustable headrest (sold separately), adjustable seat , adjustable tilt , adjustable lumbar support Set Up / First ImpressionsPhoto: Audrey LeePhoto: Audrey LeeCommerce editor Audrey Lee assembled the office chair, reporting that the whole process took around 30 minutes and was relatively headache-free. The process was fast, easy, and I was able to do it on my own, she says, though Branch does recommend teaming up with a buddy just in case.Branch provides a thorough instruction manual in the package (also available online), which guides you step by step in building the chair and carefully indicates which screws and tools are required for which part of the process. I consider myself pretty handy but not that strong, so if I can put this together by myself, its definitely a testament to how easy assembly is, Lee adds. The chair arrives flatpacked in a modestly-sized box (about 28 x 14 x 24), and since it can be fully disassembled, we think its also a great option should you ever need to move.Testing ThoughtsPhoto: Shannon MurrayPoor posture fears the Branch Ergo Pro. The chairs fully customizable support system makes it easy to spend long hours in a static position with all the adjustments you need to feel more comfortable throughout the work day. I was particularly fond of the arm rests that helped me achieve perfect elbow support (a very specific need since Ive recently enjoyed working with a laptop stand) and the adjustable tilt option gave me the freedom to stretch my back out whenever needed.
