Get nylon locking nuts. Very difficult to come loose .
You make a good point. I barely move which may help. How on earth do you cope with two people in a double? That’s less room than a baby gets in a cot!Mine seems to go loose all the time but me and my partner are both overweight and it's only a double. Probably I'm the problem as I thrash in my sleep too. But I have an organised tool box with hex keys to hand.

I would be so ashamed and embarrassed to be that lazy.I just can’t picture what could possibly have been broken that is “too fiddly” to repair. She’s too lazy, more like.
She’d be better off putting the whole thing on Facebook Marketplace as a repair job. Someone will be arsed to mend it for a bargain bed, even if she’s not.
