This firepit is several years old but we've always kept a cover on it and it still works just fine. It has a "concrete" look but the material is some kind of composite, it's not actual concrete, so it's not that heavy. Two people can lift it easily. It's about 27” wide by 57” long by 15” high, and it has a separate little cube thing that's actually the cover for the gas tank (see photos) which is 16” x 16” x 21” high and works well as a little side table.
It gives you a nice feeling of "sitting by the fire" but it doesn't overheat you.
We paid $650 for this new. I'll include the cover, although it didn't come with the table originally. The cover is almost new, we just bought it a couple of months ago.
