What kind of mousepad works best on carpet?

Get a mousepad with a spiked, honeycomb, or aggressive textured underside—those bumps dig into carpet fibers and hold it in place. A hard mousepad (plastic, glass, or aluminum) also works because it’s heavy and rigid. Standard rubber-bottomed pads slip on carpet, but you can hack it with a thin non-slip shelf liner underneath. A decent carpet-friendly pad costs $10-15.
