This will only work with Reverie 7t or 400/450/550 bed bases that had the exact same control box as pictured above in the second picture. There were a handful of these same models that shipped with the same remote but had a different control box and these newer ones will not work. If your control box did not look like the one shown, most likely you need the “7t alternative model” shown here: Reverie 7t or R400/450 And R550 (non-Pillow Tilt) RC-WM-111 Wireless Remote ALTERNATIVE VERSION- See pics (adjustablebedremotes.com)
