Having just stayed at a Premier inn and thus researched their mattresses I came across your post reviewing and comparing their mattress to your own equivalent. However I found your report to contain so many "unknown" aspects of the Premier mattress as to make your review/comparison virtually worthless. Surely to conduct a balanced and detailed comparison would it not have been a good idea to have acquired a premiere inn mattress and examined it in detail so as to be able to give a much more detailed and balanced comparison? I would certainly consider buying an alternative such as yours if you were able to provide a much more convincing case why yours would be a preferred choice over the Premier/Hypnos version.
