Buy Branch Ergonomic Chair Pro Parts From a Local Authorized Dealer or Repairman Near You

Visit the official Branch Ergonomic Chair Pro product page or use the Branch contact page to ask about replacement parts, warranty support, and repair options.

Tips for Ordering Branch Ergonomic Chair Pro Replacement Parts

  • Confirm that your chair is the Ergonomic Chair Pro, not the standard Ergonomic Chair: Branch has multiple chair models with similar names. Parts like headrests, arms, backrests, and mechanisms may not be interchangeable.
  • Check your chair finish before ordering visible parts: The Ergonomic Chair Pro comes in several material/color options, including mesh, bouclé, vegan leather, and leather finishes. A seat or backrest replacement should match your exact color and material.
  • Contact Branch first for structural parts: For the backrest, seat pan, mechanism, lumbar system, arms, and trim covers, Branch support is usually safer than guessing with a universal part.
  • Measure universal parts carefully: Casters, gas cylinders, and some bolts may be available from third-party sellers, but you should measure stem diameter, cylinder taper, bolt length, and thread size before buying.
  • Do not force mismatched screws: The assembly guide warns about alignment when installing the headrest screws. Cross-threading can strip the head or damage the mount.
  • Save the original hardware when disassembling: Put arm bolts, mechanism screws, backrest screws, headrest screws, and the base screw in separate labeled bags so you know what size to replace.
  • Photograph the underside before removing the mechanism: The Ergonomic Chair Pro mechanism controls seat depth, height, recline, and tilt. Photos help you reinstall it in the correct front/back orientation.
  • Use your order information when contacting Branch: If your chair is still covered, Branch may ask for order number, photos, and a description of the issue before confirming replacement options.
  • Be careful with marketplace listings: eBay and Amazon may show generic office chair parts when you search the chair name. Read the listing title, dimensions, return policy, and photos before ordering.
  • Replace safety-related parts immediately: Stop using the chair if the base, cylinder, backrest mount, arm bolts, or mechanism feels unstable, cracked, loose, or unsafe.

Tools Needed to Repair Branch Ergonomic Chair Pro

  • Metric Allen Key Set: The chair includes an Allen key, but a full metric set helps with arm bolts, mechanism screws, backrest screws, headrest screws, and lumbar screws.
  • Office Chair Cylinder Removal Tool: Useful when the gas cylinder is stuck inside the mechanism or base and will not separate by hand.
  • Rubber Mallet: Helps loosen a stuck cylinder or caster without damaging the finish like a metal hammer can.
  • Flathead Screwdriver: Helpful for carefully lifting small trim pieces, such as lumbar plates or covers, without pulling too hard on plastic tabs.
  • Adjustable Wrench: Useful for gripping stubborn metal parts during cylinder removal or when a repair tool needs extra leverage.
  • Needle-Nose Pliers: Handy for removing small broken plastic pieces, grabbing loose washers, or holding hardware in tight spaces.
  • Blue Threadlocker: A small amount can help keep bolts from loosening again, but only use removable threadlocker and avoid over-applying it.
  • Tape Measure: Needed to measure caster stems, cylinder height, bolt length, seat width, arm spacing, and replacement part dimensions.
  • Moving Blanket: Protects the seat upholstery, backrest, and arms while the chair is upside down during repairs.

Branch Ergonomic Chair Pro Diagram & Manual

You can find the official Branch Ergonomic Chair Pro assembly diagram and user instructions on the Branch website. Go to the official Branch Assembly Guides page and look under “Office Chairs” for “Ergonomic Chair Pro.” Branch provides an assembly and user guide with the parts diagram, hardware list, assembly steps, lumbar removal instructions, and adjustment instructions. You can also view the official PDF directly here: Branch Ergonomic Chair Pro Assembly and User Guide. Use the diagram before ordering parts so you can identify whether you need the backrest, seat, mechanism, left arm, right arm, base, cylinder, casters, headrest, lumbar, or hardware.

How to Prevent Damage to Branch Ergonomic Chair Pro Parts

  • Do not exceed the chair’s rated use: Avoid standing on the seat, leaning hard on one arm, or using the backrest as a handle to drag the chair.
  • Adjust the lumbar gently: The Ergonomic Chair Pro has adjustable lumbar pressure and height. Reset pressure before height adjustments so the lumbar does not bind or feel stuck.
  • Keep armrests locked after adjustment: After moving the 5D armrests, make sure the width and height positions are locked so the arms do not shift under weight.
  • Use the right casters for your floor: Damaged or rough casters can stress the base and scratch floors. Replace worn wheels before they wobble or jam.
  • Tighten loose bolts early: If the backrest, arms, or mechanism starts to feel loose, stop using the chair and check the bolts before the holes or threads become damaged.
  • Do not force the headrest screws: Align the headrest carefully before tightening. If a screw resists immediately, back it out and realign it to avoid cross-threading.
  • Clean fabric and leather finishes properly: Use gentle cleaning methods for your exact material. Harsh cleaners can stain mesh, dry leather, or damage vegan leather surfaces.
  • Avoid pushing the chair by the headrest: Move the chair from the seat or base instead. Pulling from the headrest can strain the headrest mount.
  • Protect the chair during moves: Remove the headrest if needed, wrap the backrest and arms, and avoid stacking heavy boxes on the seat cushion.
  • Keep the tilt and recline controls free of debris: Dust, crumbs, and pet hair around the underside mechanism can make levers and sliding controls feel sticky over time.

Branch Ergonomic Chair Pro Parts FAQ

Where can I buy official Branch Ergonomic Chair Pro replacement parts?

Start with Branch support through the official contact page. Model-specific parts like the headrest, arms, backrest, seat, lumbar support, and mechanism are best ordered or confirmed through Branch before checking marketplaces.

Can I use standard office chair casters on the Branch Ergonomic Chair Pro?

Possibly, but you need to match the caster stem size and style. Many office chairs use common push-in caster stems, but you should remove one original caster and measure it before ordering replacements.

Why does my Branch Ergonomic Chair Pro keep sinking?

A chair that slowly sinks usually has a failing gas lift cylinder. Replace the cylinder with the correct size or contact Branch to ask whether they offer the standard or tall cylinder for your chair.

Can I add a headrest to the Branch Ergonomic Chair Pro later?

Yes, the Ergonomic Chair Pro supports an optional headrest. Buy the Ergonomic Pro Headrest made for this model and use the correct headrest screws when installing it.

Are Branch Ergonomic Chair and Branch Ergonomic Chair Pro parts the same?

No, do not assume they are the same. The Ergonomic Chair Pro has different adjustability, lumbar support, materials, and compatible accessories, so parts should be matched to the Pro model.

What screws does the Branch Ergonomic Chair Pro use?

The assembly guide lists arm bolts, mechanism screws, backrest screws, a base screw, and optional headrest screws. Keep the original screws so you can match length, thread size, and head type.

Can I replace only one armrest?

Yes, if only the left or right arm is damaged, you can look for that side only. Make sure the replacement is for the Ergonomic Chair Pro and matches the same mounting style.

What should I do if the lumbar support feels stuck?

Do not force it. Reset the lumbar pressure to the lightest position, then try adjusting the height evenly with both hands. If it still binds, inspect the lumbar plate, screws, and retention tabs.

Can I replace the seat cushion on the Branch Ergonomic Chair Pro?

The seat is a separate component in the assembly guide, but it is not usually a universal replacement part. Contact Branch with your chair color and material to ask about a matching replacement seat.

When should I stop using the chair instead of repairing it later?

Stop using it if the base, cylinder, mechanism, backrest mount, or arm supports feel cracked, unstable, stripped, or unsafe. These parts affect stability and should be repaired before sitting again.

Summary
Finding Branch Ergonomic Chair Pro parts is mostly about matching the exact model. Simple items like casters and cylinders may have third-party options, but parts like the backrest, seat, arms, lumbar support, headrest, mechanism, and trim pieces should be confirmed with Branch first. Measure carefully, keep your original hardware, and use the official assembly guide before ordering anything.
