We usually take a double airbed matress with duvets & proper pillows (for Amoret & I who are wimps) & Mark has a rollmat. At the moment we are between cars & had to rely on lifts + train for Towersey & so we all had rollmats + sleeping bags. Amoret & I had had a test-night on mats & sleepingbags & it was really uncomfortable, so at the festival I was amazed!!! We had really comfortable nights - most unexpected. I think the pillows we had were a huge help - we took blow-up plastic cushions from the 'pound shop' & used them semi-inflated & wrapped in clothes. This seemed to completely alleviate that too-flat feeling. Thoroughly recommended.Kris
