Have this mattress for several months now in use, and I have to say: I will give you her no more. The mattress offers the best sleeping comfort to the smallest price. When two people with a total of 180kg weight the mattress Will not Back Down. May weigh with my 120kg which this mattress every day to sleep it still works perfectly. You hardly deforms and the slatted touched my body ever again. I would highly recommend this mattress only warmly!
