Another Coleman Comfort Double advocate. Bought ours last year having read reviews here and i must say it is very comfortable for an airbed and i didn't have to re-inflate for a whole fortnight.
Here's link to Outdoor Megastore where we bought ours.
Just a word of caution remember in this hot weather to let air out during the day because hot air expands but your air bed might not which makes a loud bang as it pops the side seam (our did two years ago) one new air bed later we learnd our lesson morning air OUT night air IN
Don't blow your air bed up too hard. Inflate it so that when you lie on it your hip is just about touching the ground, then you will not roll off during the night.
Thats the trick Bernie. When I first started camping I blew the airbed up till it was solid, thought that was what you was supposed to do, very uncomfortable. Now I blow it up till, when I lean on it I just can't touch the floor. Its very very comfortable, always a good nights sleep.
