Our quartz is being installed on Wednesday. I'm planning on leaving the top drawers empty of course, but will the lower drawers/pull outs get messy during the installation process? I'd like my living room back :)

Also, my youngest has been known to climb up on the counter to get into the upper cabinets and now that we have 42 inch uppers, I'm foreseeing more of that because our stool isn't even enough for her. Can quartz support a 60lb person? No overhangs, peninsulas or islands involved here, though I imagine the sink area is a big no. Thanks.
