Hey guys, I need help picking a chess set. I'm currently using a fairly cheap wooden board I bought at a games store, but the pieces get knocked over far, far too easily. I'm looking for a set with pieces with a huge amount of weight on the bottom, so I don't have to worry about being so careful when my hand glides over the position. And I mean really heavy. But nothing fragile like marble or glass.  Does anything spring to mind?

Plastic triple weithed. You can also have it on Wood if you want to, but they are considerable more spensive.

Metal is also a good option:

If that is not enough for you, then consider some magnetic or even some board with holes and pices with pins, like traveling boards are made for shaking conditions.
