I ordered two new mattresses for our Superking sized beds in Feb 2017 by October 2018 we had three replacent mattresses for the bed due to a collapse of the box springs around the area where bottoms would be when lying on the mattress. We have sent pictures of the condition of the third mattresses to Archers. The items are in the same condition as the previous two items but Archers say the warranty period is over and they intend doing nothing. We are now in the process of buying an alternative product from a local dealer. Howev. Er 4 new mattresses in 4 years must be a world record.
