I absolutely Love this bed base. We Do not have a split king we have a solid regular king so,￼ I was a little skeptical about the two twins to make a king but they work seamlessly together ￼ with the provided plug. ￼Also I was able to use the base with my existing platform bed, with a few modifications I had to raise the bed above the platform base but as you can see in pictures it worked out fine with a little MacGyver tweaks. Compared to the old Tempur-pedic base I had for my queen this one works perfectly fine it’s a little louder than the Tempur-pedic but other than that seems equally high-quality. ￼
