Will this work on a slat bed?

Hi liz, Thank you for your enquiry. The Adjustable Bed Rail is installed initially with the bed rail in fold down position and then both support feet slide in between the matress and the box springs. It is important to position the bed rail so that one end is even with the childs shoulder when the child is lying down and with at least a 9″ gap between the bed rail and the headboard/footboard. Depending on the frame of the bed will depend on the suitability of this rail. For further information on this product and to clarify suitability we would recommend contacting your nearest store direct.
