Think you have to be a solid sleeper like I am, if you toss and turn you'll hear the water moving about. Consider that before you buy.
Thanks for that heads up I'm a terrible sleeper for moving about, I don't wake up during the night but I move about the bed loads so that could be an issue...
I've slept early and well during the last month, but seeing as there looks like OT on for the foreesable future, i'm just making early plans.
Don't blame you mate, I've got the onset of arthritis in my wrist and knee, it's a bitch so everything I do now is for comfort and if it costs and extra few quid then it's generally worth it.
