Very stable. Shelves are made of thin coated boards. There are 2 aluminum shelves that go under the stove section. They accordion out but stay together. The bags do stink. But we put them outside in the shade, sprayed them with odor band, and after a couple days they were much better. One tube had a slight dent in it but not worth sending it back for. The wind sheild comes off so if your stove has one you can leave it off. Can use it as a table as well. Cant wait to use it.. Would buy again.
