We purchased this sectional and have been using for 1 week...so far so good. One of the (heavy) reclining units plastic floor protector things was broken so that took some extra time taking back to Costco to exchange.
Noticed that you can put 2x 9v battery, then batteries will very slowly operate motor for recline function; but I believe you have to first plug in the unit to the AC wall outlet after inserting batterries, then unplug, to get the battery only option. Which was very weak/useless.
The two non powered/non reclining sections have included pegs that screw into the respective unit.
Macy's has a very similar piece probably nicer/more durable fabric but was on sale for $500 more/$1799.
