The base and legs are sturdy made with heavy duty plastic material. The cover is a heavy duty poly plastic and seems well made and sturdy. The trellis part is flimsy/lacks proper instructions to put together quickly/and falls apart. I won't be using for tomatoes - not enough room for root system. Will be okay for peppers and herbs.

I haven't put it together yet because it's still Winter, but it seems sturdy and well made. The only reason I didn't give it 5 stars is because of the packaging. I came in a gigantic box filled with paper and cardboard and the parts for the planter were just thrown in the box. I had to take care not to accidently throw away a part because they were mixed in with the paper and cardboard.
