Is there a bar in the site hut? Or can this be it?

I need a pint!

Bought a second hand bed of gumtree this evening. Before purchase I checked with the owner that it took a standard sized double mattress, he's says yep. So drive out to collect it, it's dismantled so can't see it in it's glory.

Get home, build it, brilliant looks great, put mattress on, turns out the bed is three inches longer and an inch wider than the mattress. Grrr

Annoying, but would have been worse if the mattress was bigger than the bed, perhaps? You need a good old fashioned bolster for the end of the bed...
