The aluminium top tables don't really bounce correctly. These are outdoor tables meant to withstand all sorts of weather conditions.
If you're not leaving the table outdoors in the rain, buy a proper 18mm or thicker MDF table.
Thanks for the response. The only reason I like the idea of the outdoor table is because then my friends couldn't ruin it by setting or spillilng their beers on the table...and I have some pretty careless friends, and will probably be having some parties where I could easily foresee a table getting ruined. Could you tell me what the sears site means when it says the top is "encapsulated aluminum?" Is it just a sprayed on top, or can you actually tell by look and touch that it is completely different from other tables? What about the bounce is different? Is it softer, harder, or just less consistent?
Also, please keep in mind that this is only for fun, and I'm not trying to have any competitions on the thing.
