My EU Double mattress
Its really difficult to make an assessment, i.e. I had an older version of memory foam bed but its was beginning to sag at the edges. So here's the problem giving an opinion, e.g. because the mattress is new it would no doubt give me a much better nights sleep, and it did and does. I would say, where I used to wake with a lower back pain, that completely gone since having my new bed.
