Have these slatted bought 19 months ago in the size 140x200 because of agegebenen high load capacity and the good reviews, because I already had back problems. The processing was initially very solid, the slatted looked comfortable undstabil. Not has creaked. In contrast to the "narrow" slatted he along 3 fabric strips. In the first 2 weeks, a clearly perceptible smell of wood was available, which then decreased, but initially was clearly perceptible. In the beginning I slept well on it. Now after less than 2 years after it bends in the middle, despite the hardest setting and I have increasingly severe back pain. The fabric strips have lengthened and slide under load in the middle, so it loses even more stability. First I had the mattress in suspicion with regard to the recourse of back pain. But I have now tried three different in hardness 3 and the result was the same.
Only a block board with 14mm thickness and 140 x 100 placed under the mattress on the slatted base, brought her relief. However, I have to go every night to lift the mattress, so that there is no mold. So it's definitely rust.
I had expected at least at my weight of 85kg that I have at least 5 years of peace, but after such a relatively short time, I'm very disappointed because of my pain.
