Great versatile bed. One negative we've noticed is that the weight of two people will fall on 1 board in the middle that's just 2 and 3/4 inch by 1 1/2 inch so please check the weight maximum before ordering. The board could be doubled up, but that's extra construction on the consumer.  Two 6 inch mattresses sit a bit high on the bed almost covering side and back rails. The idea is to keep two mattresses stacked when the bed is used by one person, and side by side for two people.
