Hi All,

For years I have been buying cheap ($30) plastic desk-chair-plastic-thingy that go on the carpet to support the casters. I am 145-lb and the chair probably another 20, so not a great load at best.

But, the mat always makes divots where I mostly position the chair, not ideal but not a real problem until I want to roll a little to one side or an inch or so back. The divots are my home and will not let me have my way.

Recently Amazon had a deal on a chair-plastic-thingy that did not give way to divots so splashed the cash. Amazing stuff, but now I have another problem and are wishing for divots again. The chair no longer stays put in anyone position. It slowly moves wherever my most frequent movement is toward and lately that is backwards. So, I find myself eventually typing at stretched arms length over a five minute period.

I am on the verge of tossing this lovely mat-thingy and going back to a Divot-Master 5000.

I love the freedom of movement when I want it, but hate the freedom of movement when I don't. I have thought of stitching some Velcro to my jeans leg and gluing the Velcro other half underneath the desktop. But -- there has to be a better solution. Yes?
Metal working solution - lay a one inch steel plate to cover your
maximum range of moves and place your chair on top.

What do you use to prevent rust, Gerry? Johnson's Paste Wax,
Boeshield T9, or 316 Stainless?
Gold plate it?
