On these aluminum group chairs, we think we use one of the best manufacturers in the world – they  have been making a close duplicate of the HM model for over 9 years, using the same aluminum frame technology and the rib chair back technology as the original office chair factory. Thus, we think our chairs are well made as compared to the other replicas on the market, namely because:

  • We use Italian leather
  • Our frames are aluminum with polished arms, not chrome plated like the cheaper versions
  • 5-spoke die-cast polished aluminum base with BIFMA tested gas lift
  • Soft polyurethane wheels suitable for wood and concrete floors; chrome plated aluminum covers
