Dreams Cosmic Memory Foam Mattress

I had only ever tried out memory foam mattress toppers before so when I stayed over at a relatives house for a few nights and the double bed had a Dreams Cosmic memory foam mattress I was dubious. The mattress seemed firmer than I had imagined and fairly comfortable straight away. I suffer from neck and shoulder pain if the mattress is so soft or not supportative enough and after the first night I awoke, abiet a little warmer than normal but without the normal feeling of stiffness. On the second night I realised that I wasn't getting that normal feeling of pressure on my hips (I'm a side sleeper) and slept pretty well again. I think I would consider getting a memory foam mattress if it wasn't for the fact that they retain the heat making this kind of bed unsuitable for the warm summer months.
