The manufacture is a great quality product. If anyone says this is a cheap brand is just really bad at putting it together or really bad at taking care of it!!! I've had a lot of people on it at once (way over 500lbs) and the weight limit is only 250lbs so I really have put it to the test and it still had lots of bounce in it while loaded down.  The instructions are terrible!! No doubt about that. But some common sense and anyone can put it together.
