Got a foam mattress less than two years with a 25 years guarantee. You think wow. When you think 25 year guarantee no worries. Call Ikea call centre telling them my mattress sinks in the middle causing me back problems. They say that's fine looks like a back batch of quality foam. We will send a company call Ecomaster to have a look. Day before Ecomaster was meant to come over they text me they coming at 8am to 1pm. So I told work I'll do half a day come in the afternoon, lost out on my wage then but at lease it's not a full day. Then I got a text just before 5pm that they changing the time and coming between 12 to 7pm. I lost a full day of my wage. I had to ring work in the morning telling them I can't come in the afternoon they wasn't happy. So Ecomaster guy come in done a lot of test. Check the floor flat, the bed base flat and even laid in my bed but not willing to talk to me just how often I turn the bed and how long I had the bed. Ecomaster went off saying you will get in touch with Ikea. They sent me a letter today saying they isn't a manufacturer fault or defects. Then saying the damage had been caused due to the care instructions not being followed. Will not take further action. What a company!!! I slept in that bed and I've got another mattress that over 5years. I don't get any back problems with that. A warrantie not worth a penny. A company I won't trust.just lies and lies
