not of interest to everyone I understand, but if anyone is thinking that they are not sleeping correctly at night due to theirs then I suggest they change. I had an old mattress which was I bought as a stop between buying a new bed. New bed came but didnt like any of the mattresses, so decided to wait a while.
Anyway 4 years later I was still sleeping on the temporary one and it was doing my back no good. So a couple of weeks ago I went out hunting for a new one.... finally found a decent new pocket sprung one. Got delivered on Tuesday and have had the best nights sleep ever!!
make the change!! never felt so fresh during the day (egyptian cotton sheets do help)
