Thought i would write a long term review of the king size mattress topper. On receiving the item both my wife and i were very happy with the extra layer between us and our memory foam mattress, although the 10cm thick claim is very ambitious. We enjoyed extra comfort for a few months but after a year of owning the topper there is very little thickness left to it no matter how much plumping, shaking, washing etc is done to the topper. If i were very generous it is now at best 3cm thick so the 10cm thickness turns out to be 70% air that you cant get back into the topper by plumping etc after a year of use. So a very expensive topper also strange how the description no longer mentions the 10cm thickness, I wonder why???
