Does anyone know the dimensions of the fiberboard/hardboard bottom panel that slides into the Hemnes drawers? I have the 6 drawer dresser (003.604.17) and one of the drawer bottoms is completely destroyed and the others aren't in great shape.

I'm hesitant to measure the ones I have because they're all warped and don't want that to impact my measurements. I tried looking on the website but couldn't find specific measurements for specific pieces.

I'm trying to find an easy enough way to replace the bottom panels. I'm guessing some other similar hardboard product cut to size would be the way to go. Thanks in advance for any help or ideas or suggestions!!
