We go camping every summer. I am so fed up with having to buy new airbeds every year! This year I gave the Tesco £7 ones a miss and bought £30 ones and they still deflated overnight and 2/4 got a puncture.
In a shop I tried one of those nylon camp beds with fabric stretched across a metal frame and it felt so uncomfortable.
Short of hiring a van, and taking our actual beds from home, does a non-inflatable, comfortable way to sleep in a tent actually exist, that will last a few years?
