My superking link mattress was short of the normal length of 2m and particularly unsightly on the corners which were very rounded. Mattressman claim that there is an industry standard of 2 inch tolerance and that our mattress did not exceed this. No-one disclosed this "tolerance" at point of sale and having bought beds over a period of 50 years I have never experienced such a thing before. Also at point of sale Mattressman particularly praised The British Bed Company, the manufacturers of the mattress, without disclosing that it is under the same ownership. I would never deal with this company again.
