This remote is a genuine OEM replacement remote for the Serta Motion Essentials III adjustable bed. Look closely at your old remote buttons when purchasing... the 4th gen remote replaces the "zero g" button with a massage button. We can order remotes other models but you must view our other Amazon listings. Call or email if you lost your remote and we can look up the sku number. We include directions for easy syncing! Programming is required (using the power down box under the bed) and instructions are provided.
