I had been looking for a Conversion Table Top for a couple of years.  I did my homework and I'm glad I did.  I was going to default to buying a top that matched the brand of my table but decided to research other options.  The Joola top is hands down the best option I could have gone with.  It is heavy like others have mentioned but that's a positive in my opinion.  The top doesn't move on the table.  Not only is that good for play, it makes sure the top is not damaging my table underneath.  This is the best looking, most sturdy and live action table top on the market.  It has excellent padding underneath, is easy to setup/take down and lays true on the table.

If you're looking for a conversion top, end your homework here and buy the Joola in black!

Pros: Sharp color, sturdy, lays flat, heavy to prevent sliding, lays true on the table, true bounce and so on....
