I bought some 1x3 oak, removed the black plastic uprights from the bumpers and cut the oak strips about 4 inches longer. Turned the pads around, put the oak strips in the brackets and remounted the bumpers so they sit a little higher. Now instead of the bumper top only being 2 inches above the mattress they are about 6 inches above with the bottom being flush. Now DW will let the kids sleep up there
