Vekkia King Bed Wedge Pillow for Headboard Gap/Bed Mattress Gap Filler Wedge,Bed Gap Filler Close Gap (0-6"),Stop Pillow Falling Down-Gray(76"x10"x6")

I would recommend getting something to put in front of the bar on the bottom screen, it gets easily bent and dented if hit. I used a bed wedge headboard pillow on Amazon and it worked great. https://a.co/d/07gDObDg
