Bought a Stingray for my family of two adults and two kids aged 4 and 7. It was specified as having a capacity of 3 people or 2 adults and 2 kids. I am not sure how that is going to work since the kids seem to roll on top of each other and towards the centre. The instructions said the bottom straps are calibrated at the factory but we needed to adjust them bottom straps after the first night to prevent everyone from rolling to the center. Overall I think the product is great for 3 people but I'm not sure yet if it can fulfil the promise of fitting two adults and two kids.
