I thought I was getting a patio table with a 2" concrete top. I sent in a question and was told that's what I was getting. The table came with a little flyer that stated "All Weather Ivory Compost Table Top." Inside the brochure it was described as a "poly-resin blend with a "concrete like" look". The top is about 5/8" thick with a 2" trim around it. It is steel reinforced which can be seen only if you look underneath or during assembly. It is about 200# so it won't blow away. We'll see how it holds up in south central Texas. We have four chairs and I asked the CSR about recommendations for two swivel rockers to match. She said she'd get back with me and never did.
