Both of us have back complaints and bought a Tempur a few years ago, woke up first morning not feeling so stiff and can both turn over without disturbing the others sleep, you dont get the bounce you would with a normal sprung mattress, so more restful. Only complaint it it is so hot, we even put a well padded mattress cover on it, but were still hot. We slept in the winter with a summer low tog duvet, but still kicked it off . Unfortunatley the matress split in one area and now is on the spare bed, where it will only get occasional use. We purchased another memory foam mattress at a 1/3rd of the price, its just as good but also just as warm. Shop around.
