When we bought the mattress, we were just really excited, unfortunately, after almost 10 months, we need to determine which has suffered but quite the mattress. But one must also remember that we are always in pairs on the mattress and bring together good 160 kg on the scales. Make it unfortunately always faster Kulen from lie and we must often times turn. Sleep is but the still quite good and on the whole makes the mattress a good job even if you have every now and then rotate.
