Joystick Cushion/Stand?

I have a Sega Virtua Stick and I position it on my lap, sitting on the floor and find it digs into me as it's quite heavy and sharp edged(ish). I was thinking of buying some kind of stand for it, so I can place the stand on the floor and sit the stick on top of it, or some kind of board for my lap. This Belkin CushTop looks almost perfect;



were it not for the slanted design - I'd prefer a flat top. So I'm leaning towards the Belkin CushDesk, which looks to have less of a slant;



and less cumbersome too.

For those who have faced the same issue, what have you used as a workaround?
