Our Story

Mr. Alan Lee, inventor of B-Free Chair and founder of B-Free Technology Limited, has been engaging in product design for more than 20 years. He has never studied electrical engineering but has created B-Free Chair, our concept version, and B-Free Ranger, our market version, with his dedication to help others. He learned the story of a disabled youngster who caged himself in his own house for 8 years. What kept him away from the wonderful world outside were the 5 stairs at the lobby of his building. His passion was ignited instantly and decided to do something that can help the disabled to regain mobility, to overcome obstacles and to live in a world with no barriers.
