I've got a nice leftover quartz slab that my contractor finished into a tabletop measuring about 25" x 49" and it's 2cm thick, weighing around 100 lbs. I'm thinking of just placing it on a 'Desky Dual Sit Stand Desk Frame' which can handle up to 300 lbs. Is this a solid plan? Do I need to use plywood to prevent cracking, or should I secure it with some adhesive like silicone epoxy? I don't have a lot of tools or experience, so any tips would be appreciated!

I built a desk a while back using a thicker quartz slab, and the quartz supplier advised on the support distance. If I remember correctly, your supports shouldn't be more than about 18" apart, so consider that. I used brackets to support it in the middle and at the ends, which worked well! Good luck with your project!
Using plywood underneath is a smart move as it can help distribute the weight better. A simple silicone caulk will also keep everything secure and prevent movement. That's what I've done for my own setups, and it works great!
Is it a bad idea to let the plywood 'acclimate' in the room where your desk will go before you set everything up? I've heard that might help prevent issues later on, or is plywood pretty stable as is?
Just to clarify, should you put caulk between the quartz and plywood, the plywood and the desk frame, or both?
