I have 2. One is a concrete round. I love it but don't even think about moving it. That thing weighs a ton.

The other is a Lifetime plastic table it has a steel frame with molded plastic benches and table top. It's about 300 or 400 at Lowe's, but worth it. I will not own another wooden one. The plastic is durable with large adults sitting on it, but you can wipe it down easy and move it wherever you want.
