We bought this table to use for adults camping. Unfortunately, it's a bit shaky when you sit down on the somewhat small seats, and if more than one person sits down at a time you have to be careful about placing your weight just right. My husband and I are both under 150 lbs. each, and felt like we were taxing the ability of the table when we sat down at the same time. We tried to stay on opposite corners, but it still felt a bit awkward and unstable. My sister had one of her own, and she and her husband (both of average height/weight) accidentally cracked the seats by just sitting down without carefully lowering themselves down first. You shouldn't have to be so dainty with camping equipment! The idea is great, though, and it works perfectly for the kids. As long as they don't climb on it!
I got one of these for tailgating thinking it would be very convenient. Except it is so flimsy. You have to sit very carefully so you don't break it when you sit. It's just okay for tailgating since it folds up small but I wouldn't recommend it. I think you might as well just buy a regular folding table and chairs.
