Ok, so this is about a mattress, and the problem with reviewing a mattress is unless you constantly spend time in different beds its almost impossible to compare, and if you did you would have to be a voyeur to lift up the bed clothes to see who made it, who does that!
If your reading this its because you are already considering to buy a new mattress for certain reasons, probably its past its best or your health isn't as robust as it was, and you are looking for more comfort whilst sleeping, this may be due to back ache, which again may have various causes, mine was due to sciatica, and if you look on the net the NHS show you exercises to help/cue this which they did. Having said that we bought what was probably the most expensive, over 2000 pocket springs, very comfortable, but you need to buy what you can afford bearing in mind that you spend a third of your life in it. Dreams are people that specialise in beds, and yes you can probably buy something cheaper elsewhere, but Dreams have a system to measure posture and body weight to give you the best selection to chose from and in this day and age that's what you want.
