Ok folks,
I did order two of these and used them for the first time last weekend.
DON'T BUY IT!
It's absolutely rubbish.
The canvas is secured to the metal of the chairs with PLASTIC screw receptors. I'm 14 stone and when I opened the bed out and stretched out, the first thing was that I could feel the metal bars in numerous places making it very uncomfortable. Secondly, the first time I (gently) turned over, all four of the retaining screws "popped" out leaving me in a heap of twisted metal.
The next night I set up the second new one hoping it was a duff one-off, but alas no. The second one behaved in exactley the same manner.
When I returned home I had a closer look and discovered even the long thin screws securing the metal legs to the plastic feet were falling out with no help from me.
I have photos if anyone's interested but for God sake don't waste your money.
Feedback has been given to the supplier but I'm not expecting an answer.
