The adjustable beds seems to be a very well made product.  I got the split king, which I should not have done.  They are two separate XL twins and you need to have or purchase 2 twin XL beds to make this work.  I thought I could just put my king size mattress on the mechanisms, but it was not the case.  So, l took these pictures to give you an idea of what it comes with.  You also get message, which is a nice thing to have.  I’ll put it in my bedroom when I purchase 2 XL mattresses in the near future.  The picture only shows one of the two which is exactly the same as the one shown.  I just didn’t want to open them both since I don’t have the right mattresses right now.
