The top is described as 'Faux Marble' which is very non-descriptive, it feels like a giant heavy tile with textured-ish top over wood (see picture). Very solid overall.

It came pre-assembled in a giant cardboard box with a wood frame and tarp on the outside to protect it from moisture. It was huge and heavy, you will need two people or more to bring it inside. 

This table is really solid and so lovely with our space. There was a minor stain on the outside of one of the seats from being packed against one of the metal legs, but it was really easy to clean away. 

A minor thing would be the table lift mechanism is not as smooth or as easy as other ones I've seen due to the weight of the top. 

Overall would highly recommend this for additional seating and a coffee table in one (or in our case, as footstools, too).
