I used the "Small Helm Station Pad" from Seadek last year. Perfect fit between the console and the livewell on my 1999 21DV.
Overall I'm very happy with the pad. It stayed in place (see notes below on how I installed it) and provided a nice firm cushion without tripping over it.
I ordered it online, one thing I didn't notice before receiving it was that it is a pseudo-permanent install. The entire back of the pad has a high-quality adhesive on it, so basically install it like a giant sticker.
My boat has the inspection port for the fuel tank in the same area, so I had to come up with an alternate installation plan.
One option would have been to cut a hole in the pad. If left as is, this would have left the area on top of the access port uncovered, but it would have been a small 'hole' that I figured would bug me.
Another option was to cut a hole in the pad, and attach the cut out section to the top of the access port. This would have cushioned the whole area, but due to the thicknesses of the materials, it would have created a raised spot that I'd be tripping over.
I ended up with a third option. I shopped around for an indoor/outdoor doormat that was approximately the same thickness as the height above deck of my inspection port. I cut a hole in the mat for the access port, then without removing the backing on the seadek pad, I placed it on top and lined it up so that it was centered. I then took a razor knife and cut the doormat flush with the edge of the seadek pad, then removed the backing from the seadek pad and stuck it to the mat.
This made the seadek pad have a flat surface to stand on and made it easily removable for access to the fuel tank. I was worried about things flying around, but the weight of the mat held it in place, and I never had to touch it for the entire season.
Hope this helps.. I like the pad a lot, and purchased it based on the good reviews it got and the fact that it was relatively firm. I didn't like the idea of tripping over a 2" high section of foam that felt soft but didn't really provide any support.
