This states in two areas on the bed’s page that it is compatible with an adjustable base. We ordered the California king just to be sure and the bed was still not wide enough to put the one side rail on. We made it work. We had to purchase a board to screw on the side to hold the bed together. It’s an okay quality but they really need to reword their description. This bed does not accommodate our adjustable bases but we do like the bed.
