The support frame for this item is very poor quality. The middle isn’t supported by anything except 2 small pieces of 1x1” lumber. Definitely wouldn’t support the weight it states. That being said, it’s only 350, if you are a bit crafty (like me) you could use the outer frame and create a platform inside it like I did. I was expecting the quality to be a bit better, but you get what you pay for. If you don’t intend to do some extra work, don’t bother buying this.
