Hi. I am hoping someone might have a good idea about this. I have a 66 gallon hex tank (free, scratched up) I am trying to decide if this tv stand will hold under ~500+ lbs. I weight 250 and feel very stable on it, but that is not good enough. I was thinking it could use a rear middle support (maybe front but would rather not). It is very thin pho plywood on the side panels, with the four corners being 2" x 3/4" hardwood? maybe pine. Those four corners are the only real supports. The stand almost 40" tall. Any advice that is good advice is greatly appreciated.
