I bought an IKEA mattress last year and so far it has been great. But I have just noticed a large tear in the foam that covers the springs 😢 I've checked the website and they have a 25 year guarantee but it only covers defects in manufacturing and workmanship, not wear and tear, and it's at their sole discretion as to which they class it as, so I am not hopeful! Can anyone reassure me that they have amazing customer service and will surely replace it?? I'll email them tomorrow (can't email them out of hours bizarrely) but just curious to hear others' experiences.
