The retainer bars work with any size mattress and any model adjustable base. Simply attach to the side of the bed to prevent the mattress from shifting when adjusting the base.
Easy to install. Was worried that being on the side would create a hazard to getting out of bed in middle of the night, but is practically invisible and does not interfere with access or exit from bed. mattresses do not shift. Well done!!!

The mattresses can slide apart when we put the split king together. With the bars there the problem is solved.
Love the beds!
