So at Neocon we got introduced to Keyn in 2017. However, it is worth the look back! Check out how far this chair has come. The back does flex with the user. The chair can be poly or fabric seat and back. The frame is in Black and white, along with the option of a Polished Aluminum base! Check out this link for the product configuration to see how you can design your own Keyn Chair for your office!
