Do you think these are strong enough to support another, full with LPs (a few hundred pounds), on top of it? I figure I'd need 4 to fit my collection but would have to stack them.
The top, base, and sides are all 1.25" thick so I would think it might be safe. I haven't tried though I so can't honestly say. If you put the supplied front to back length footers on, the weight should be all along the top edge down the sides. If you chose to not attach the footers, the weight would be distributed over the thinner cube sections as well. It might handle it, but if the bottom piece had the attached footers, then I'd definitely add something under the base. Hope that isn't as confusing as it reads.
