About this item

  • 🥇【Universal Size】This gaming chair base replacement is suitable for most chairs on the market including Herman miller (office chair, game chair, office chair, executive chair). Casters: 7/16 inches x 7/8 inches (11 mm x 22 mm) and gas cylinder 2 inches (5 cm).
  • Of course! Please provide the lines you'd like modified, and I'll help you rephrase them to avoid duplication while maintaining their meaning.
  • 🥇【Safety & Floor Protection】Our office chair base replacement prioritizes stability, preventing floor scratches and enhancing safety by maintaining a low center of gravity. This not only safeguards your floors but also saves you from the costs of replacing your chair.
  • 🥇【Budget-Friendly Solution】Opting for a chair base replacement at a fraction of the cost of a new chair is a smart decision if your seat is still in good condition. Save money while retaining your beloved chair.
  • 🥇【Premium Craftsmanship】Crafted from top-grade chrome-plated metal, this heavy-duty base features a polished matte finish. Its robust tubular iron build, reinforced with sturdy screws, ensures enhanced load-bearing capacity and safety, supporting weights of up to 2500 lbs.
  • 🥇【100% Satisfaction Guaranteed】Very easy to install and replacement with our simple and clear instruction sheet. If this doesn't fit your chair, you can simply return it.
