How I wish I'd read these reviews before spending £600 on a mattress. I only had mine 2 days and realised I was sleeping in a dip and it was sagging. I didn't buy the base from them so when they sent out homeserve he initially was shocked by the amount it had sagged. But then he said it's because you have a fault in your divan base. That maybe so but that it a small area where my feet are. They are now refusing to do anything about it. I suspected it was a second hand mattress that they had delivered. Please please don't waste your money. Find somewhere that will give you a money back guarantee. Dreams don't!!!!!!
