Very disappointed with dial-a-bed mattresses quality

It pains me to be making such a review because you expect mattresses to be of good quality because that’s where you rest and sleep on after an exhausting work day. I purchased a mattress on the 30th of march 2021, which later after a year became faulty the springs were coming off. On the 23rd of May 2022 I logged a call regarding this and it was a difficult experience to have the mattress replaced, however at the end it was replaced with a new different mattress.

After having received this mattress I noticed that sponge/foam gets flat and does not recover. I have a sleigh bed, so the mattress is flat on both sides and at the center it’s still in good condition as I do not sleep on the middle of the bed but rather on the sides. At first I thought it was the planks of the sleigh bed only to note it’s the mattress upon inspecting it. The maximum weight is 60kg and I do not weigh 60kg unfortunately I weigh more than that. And my initial mattress did not have a max weight of 60kg. I don’t think this is any fair to me as a customer that when they replaced the mattress this was not brought to my attention. It is not fair. I would like to get my refund as I am very dissatisfied with the service I have received thus far. Each year I must experience the same issue. Sleeping on a faulty mattress is very uncomfortable you wake up exhausted each day!! The quality of your mattresses is appalling! This is the second time in a space of 2 years.
