Do Not Buy Edblo goods

DO NOT EVER BUY AN EDBLO MATTRESS. We bought one just over a month ago and it started to sag after three days. The factory responded to our complaint ONE MONTH after we made the complaint. Needless to say their response is 'there is nothing wrong with the mattress and body impression needs to be 4cm before it is deemed faulty '- by 4cm you will feel your base under the mattress. It would be interesting to actually cut the mattress open and have the springs tested in a lab as judging by the other complaints on Hello Peter it's an Edblo failing. DO NOT BUY EDBLO!
