A:Answer The base is built , you have to install the front uprights and the platform and arm rests and the screen , it took me three hours to assemble , the belt is on already , no difficult stuff but you have to know your tools and what to do , the uprights can be tricky as there heavy , you need a helper , we took the box apart outside and carried in the base with the track , this part is really heavy and you need two strong people to lift it in the house and through the doorways , good luck
