Our dreams mattress has a ridge in the middle , I feel like I’m falling out of bed, they sent an independent tester who said the mattress was not faulty, he didn’t seem to test it out properly, just had a piece of string with a weight on the end and said it was normal to have a mound in the middle?! The independent tester that works for Dreams...mmm Unsure about this. Any idiot can see there is something wrong you don’t need any training for that . Dreams are not interested and we will be disposing of this two month old mattress (£850 ) down the drain. Not so much Dreams more NIGHTMARE.
