Hi there - here I am at 04.00 hrs being unable to sleep - I normally sleep on my side but I'm now in agony with my shoulder - we have just changed our mattress and went for a 2000 pocket sprung with a natural filling - clearly it is not up to your build standards !!! I now need something that will provide me with an uninterrupted nights sleep. I'm 6ft and my wife is 5.7" - I'm 13st and she's 9st. We have a sleigh king size bed with normal wooden slats. We would like a natural filling and I've been pondering over your Artisan Luxury mattress. Can you please help - any advice would be greatly appreciated.
