We bought this couch on New Years Eve. By the middle of February all 3 power units for the recliners had failed. We took a two week vacation in there, so the couch literally lasted for 1 month before all three recliners became inoperable.
Costco said we can return the couch, but that is two trips with the truck.
We like the couch, but the power supplies are junk, make me wonder how the rest will last.
The power supplies do work with batteries, two 9 volt. But as others have said the motors are then very slow.
The power supply puts out 27 volts, two nine volts wired in series is 18 volts which partially explains the slow down in speed.
