converting dining table (felt/foam/design suggestions)

[homegame]

I have a nice dining room table that I'd like to use as a pimped out poker table 1x/month. I don't have the skills to construct a full blown table, but definitely want the best foam/felt and DESIGN.

The table is a circle 54x54 or an oval 54x65/76/87 depending on how many extensions I use and I'll need to convert it back after playing to keep peace with my roommate.

Any advice on material, design and/or construction.
