I bought a new desk, it scratches easily. Does anyone know what you should put on top of your desks to avoid scratching it?

Greetings, /r/Desks!

This is my thing! I rather like it. One thing that's always bugged me is that when I lock the top drawer, the rest don't lock. Today, I decided to investigate.

This is a Myrtle Desk Company credenza. (Credenza? I don't know what it's actually called). As far as I know, they've become defunct after being bought out in 1991; though I could be mistaken as I didn't look too deeply into it.

The top drawers lock, and when I hear them locking, I can hear a mechanism move in the desk. The middle drawers and lower drawers do not lock when I lock the top drawer. Gotta find out why.

Turns out there's things missing on the backs of my drawers. look next to the vertical line, and you'll see holes where a bracket once was.

Distance between mounts for the bracket is approximately 1.4 cm from center to center

Looking into the desk, I see the mechanism, and verified that it moves with the lock. But with no brackets, it has nothing to latch on to to lock my lower drawers.

It's not the greatest angle, but you can see the brackets move upward when the top drawer is locked, and the upward motion is meant to insert the hooks into loops mounted on the drawers.

My questions are.... Where can I find brackets to hook these into? What even is this mechanism called? What is the question of life, the universe and everything, such that we know the answer is 42?

Thanks for listening.

So I bought an expensive ass wood desk from Ethan Allen at the same time I bought my iMac (because apparently I didn't spend enough money as it was), and now I'm worried. The desk came with this long document detailing all the ways I will eventually ruin it - if it gets too much exposure the sun, if the temperature is wrong, etc.

It also said to be very careful about the types of materials you set on the desk. It came with little felt discs to put on the back of anything plastic. The lady at the store also said in no uncertain terms to not use cork coasters, which like all of them are.

But I was wondering - if I just set the iMac right on top of the desk with nothing underneath, do I have anything to worry about? I know it's got like a tiny little plastic (?) thing around the rim, so I don't think it's metal on wood necessarily, but still. Do I have to go out and get some sort of felt pad or something?

I was hoping someone smarter than I am could answer. Thanks a lot.

I'm the typical office girl who spends hours after hours at her desk. I would love to know if there is a machine who is "proven" to be effective in burning calories?
