Why Certifications Matter When Choosing Ergonomic Office Chairs
When selecting an ergonomic chair for your workplace, choosing models that carry respected certifications — such as AFRDI Approval, Greenguard Certification, BIFMA Compliance, or Commercial Rating — ensures you're investing in quality, safety, and long-term performance. These standards guarantee that the chair meets rigorous benchmarks for durability, user health, sustainability, and intensive-use suitability. Whether you're outfitting a single workstation or a full commercial fitout, certified seating provides peace of mind for procurement officers, facilities managers, and WHS teams alike.

We purchased the chair for our 24/7 operations team — it’s hands-down the most supportive chair we’ve had. The seat cushioning is firm but comfortable, and the adjustments are perfect for users of different sizes. Great for long hours and rotating staff. Solid investment.

Testimonial
Hi Tina / Adam,
I am writing to provide you with feedback about my
experience purchasing a chair from your business.
First of all, this is our third chair in under five months. We purchased one from Amazon and replaced the first one with the second one using the credit provided by Amazon.
As we didn't have much luck, I decided to contact the office corporate based on my previous experience a few years ago when I purchased the Sylux Big Boy chair.
I can confirm that the service, quality of the product and your prompt delivery remain the same.
When I approach Lisa, I explain our difficulties in finding the right chair to suit our non-standard desk height and the person's height and weight who uses the chair. She makes it seem like nothing is unheard of and assures us that we can find a chair easily, and she
will send us some options in a day.
As promised, she sent the options, and we went back and forth with questions and clarifications before finalising the chair and purchasing it.
During this entire process, I found that Lisa's attention to detail helped us secure the right product. Her patience in answering questions through back-and-forth emails, combined with her commitment to finding the right product and delivering promptly, is exceptional.
We are incredibly pleased with our purchase and the quality of the product, as it meets all our requirements. It's functional.
I would like to take a few minutes to write about my experience and express my appreciation for the fantastic service you provided
with this purchase. It proves the point that you don't need to be a big
corporation to provide an exceptional customer service; a family business with a bit of attentiveness, patience, and commitment could deliver a memorable and exceptional purchase experience.
Lisa deserves praise for providing this service. This feedback helps you continue to offer the same level of service to everyone, ensuring your business maintains the same high standards in the coming years.
Thank you for this opportunity.
Kind regards
Kris
