Now I've found the secret to camping without absolutely fucking my body, I need to find an ultra lightweight camping bed. I'm a bit sore today but 100x better than I was after EMF. A lot of the pain could be put down to lots of walking, standing and some sort of dancing.
I don't get on with airbeds so I got a cheap camping bed that would actually fit in our tent. Most are longer. It's not perfect but it really helped. Now I've proved the concept I'll look into a better one. https://www.halfords.com/camping/camping-furniture/halfords-essentials-camping-bed-676630.html
