It took my over 1.5 to partially assemble the chair and still not done as user instructions are not user friendly as they only provide pictures with no wording on step by step instructions; not happy with this manufacturer
After putting it together and all went together easily. I use it in my home office area. I like that the arms rests flip up high enough that I can slide out of the chair without being attacked by the arm rests. Comfortable and easy rolling even on carpet.
