We bought a Tempur mattress and as we know now most Tempur mattresses have too much memory foam and are therefore uncomfortable if one sleeps more than just a short nap. In fact this mattresses cause severe back pain and pose a health risk. The reason is that memory foam is heat responsive and feels quiet comfortable initially. This leads to remain in the same position for a long time and one sinks deeper and deeper into the thick memory foam which gives no proper support any more and one sticks deep in a dip with the spine out of shape. We spent a huge amount to have a better sleep but after realising that we can not sleep on this mattress we were told that there is no way to go for another mattress even if we would choose another Tempur product with less memory foam. So we can only warn to buy this mattresses which feel good if one tries out for a short time but it is over priced anyway, extremely disappointing in sleep comfort and finally a health hazard and as soon as it is paid nobody cares to admit the serious faulty design. Keep away from Tempur. But much more: Keep away from Benson for Beds because Tempur offers to exchange any mattress but Benson for Beds principally not - even if they deal with such faulty designed products. Previously we had a simple mattress with only 5 cm memory foam which was wonderful because one does not sink in almost unlimited but we spent a fortune compared to the old mattress and now we know better.
