Hi Blunderer, we have just replaced our red/blue with a double one called a flock air bed, it is a lot nicer to lay on than the blue/red as it has a nice smoother surface to lay on it was £12.50 the singles where £8-50 but I need to blow it up with my tyre inflator ,it takes about 15 mins, they had the same one in the shop that inflates itself but that was £26
Another vote for the Coleman. I've usually got two kids in with me, and comfy as anything, No all roll into the middle, or poor old mama sinks off one edge - nice and even all round. Totally Brill,
