Nevertheless promised when held longer. The sun has an adjustable headboard / footboard. It works like a slatted frame, ie you can set it up gradually and to get them back into the horizontal, you have to have raised all the way up it once.
The first time you use, is now a hinge broken out. The undergrowth where the hinges are screwed, has only a thickness of 5mm and 4 cog a thread length of approximately 1cm. So what can never, ever be designed to 250kg.
I then today, attached between the hinges and the undergrowth of the head .- / per foot part hinge, depending on a solid wood bar. These are 40cm x 10cm x 1cm. There, I've screwed the hinges on it and it screwed with a total of 12 Schauben on the undergrowth. For sample I put my son (50kg) on the deck. It holds, but he is unlikely to be much harder.
Conclusion: In the horizontal use, a great deck with a high comfort. It is in the horizontal use very stable and despite my size and higher weight, I'm free of fear on her. The cushioning is very good, and will after the application back to its original form. The movable headboard is however in my view, a total misconstruction because the undergrowth is just too thin.
Since I only in the horizontal use (the one with the headboard was just a test) the sun, outweigh the benefits for me. If going to want to use them for cosmetic applications, however, someone (while the headboard is generally upright), so I would advise against the sun.
