This is the worst mattress I have ever owned. The foam started to break down on the sides of the bed and in the area that I sleep immediately after purchasing it. After a few years, the area where I sleep became permanently indented. It has worsened my back pain. The side walls are also collapsing so significantly that it is not safe to sit or sleep close to the edge of the mattress. I purchased the 10 year warranty and I am currently in the process of trying to claim that warranty. The Dormeo company is making the process a nightmare. They are requesting a ridiculous number of pictures. They do not want any pictures with a person on the bed, which is when it has the most significant indentations. The pictures they are requesting require multiple people to assist with, making it impossible for a single person to submit a claim on their own. I highly recommend never purchasing this mattress of dealing with this difficult company that does not want to replace their faulty, and dangerous, product. I would give this review zero stars if I could.
