we have a set of oztrail bunks,
Got a set the same(oztrail), can use them as individual beds. handy to throw in the back for a couple of nights stay over at the outlaws. Yeah they are heavy and APITA. They pack up into a bag(Cricket set size), you've got to slip the framing through the stretcher bedding.
Also got a set(brand Outdoors) that folds up to two individually flat pieces that goes into a bag(1m X 1.2 x .75mm) again it"s heavy.
With this one, the stretcher bedding stays attached to the framing.
The reason we have two, when we had the trailer tent camper(with three kids) it was the same price kinda, to buy a bunk set than one individual stretcher bed. We also bought bed rolls for them.
They both have good points and bad, neither here nor there.
Now I've never slept on either of them, only used for the kids.
