Re: Pulaski Springfield Power Reclining Sectional

I purchased the floor model, when I got home the cords were missing that plug into the three recliners. After dealing with the managers for a week, they ordered the cords and finally arrived today, three weeks had gone by. The package only had two cords and they look nothing like the ends that are on the recliners. The guys at Costco can't give me any info that works. Great.
I see in the discussion some of you talk about a DC box, and some don't, another item that I didn't receive. Is this box needed? Here are some of my questions and thoughts, please help
>Is an adapter and DC box required, or can you go direct to 120V AC current, basically plug it into the wall?
>Is the special end on the cords from the three recliner pieces only shaped that way for the DC box for show room operation with batteries?
>If an adapter isn't needed to convert the voltage down, I will just cut their end off and install a different one that I can then plug into the 120V AC outlet and quit chasing Costco.
