I bought my bed in June of 2015 so not quite four years just yet however over the last 6 months or so I've been experiencing really bad back pain every morning so bad that that I can barely get up from my bed or it takes me ages to hoist myself up - baring in mind I sleep on my side and not my back. I thought Dreams bed had an 8 year guarantee so I'm so perplexed as to why it's causing me this much pain barely four years after buying it. I don't have any medical conditionon neither do I work in a labour intensive job. I now have no other choice but to buy another mattress but I won't be purchasing from Dreams. Not again, ever.
