Should I get a non-slip mousepad for a laminated wood desk?

Yes, you want a non-slip mousepad on laminated wood. Laminated wood is slick, so plain rubber bottoms slide around. A non-slip base—sticky gel or grippy silicone—keeps the pad in place, which is essential for gaming or precise work. It costs about five bucks more and is worth it, but stick with a known brand to avoid residue.
