Well this is dreams outcome of our mattress tests.. please note the dates on the pictures..our first test that was done measured that the bed had sunk 30mm and bed was deemed not faulty,, weeks later bed got worse so had another inspection done... this time the measurement of the bed had only sunk 10mm mmm miraculously this bed has has risen in size... plus all the information on the test was wrong... saying the mattress was 13 months old but was only 7 .... the string test to test your beds do not work and the card always protects the retailer (DREAMS) (UK'S LEADING BED SPECIALISTS ) what a joke .. see pictures attached people must be aware this company has terrible products they stole my £1032
