Serta's best-selling adjustable base is now upgraded with whisper-quiet massage settings and USB ports for convenient device charging while you are in bed. A wireless remote lets you adjust the head and/or foot of the mattress so you can find your perfect position, while our pre-set button quickly and conveniently returns the mattress to flat. Additionally, the 3-in-1 adjustable legs ensure this base will be the perfect height for your existing furniture.
