This is a replacement conversion kit for the now discontinued Serta Motion Perfect 1.0 Remote. See our other listings for other model Serta Remotes. This will not work with other models. As of 2018, the original remotes have been discontinued and are now replaced with this 2 piece kit (Control box/power cord and new grey remote). You will have to unplug four cords from your old control box and plug them into the new one we provide. Then, using your old power box you can plug this new unit in. We will already pair the new remote. One other cool thing with the conversion is you now can customize your presets and for $119 more can purchase a 2nd remote to pair with the same box so that you can have a remote on each nightstand if you have a queen size bed for example.
