I bought 10 year guarantee for the mattress I bought and after 3 years my mattress was gone so soft that I was unable to use it and was having back issues. I called customer service and they arranged the technician to inspect and I was told that technician will give me a call day before his visit. I didn’t receive any call and the technician showed up at my house and inspected the mattress when I was not around o I couldn’t actually tell the technician what was wrong. The report came out that there was no manufacturing fault and they can’t do anything about it. The 10 year guarantee apparently covers loss of resilience and shape. Do not recommend dreams to anyone
