We had previously had a brand foam mattress with 7 zones and hardness 2, this mattress was too soft, the supporting effect was close to zero. The Badenia- mattress we ordered in hardness 3. She has only one zone, but the combination of innerspring and foam spine is optimally supported, one fixed, but not too hard and sweats less, than on a pure foam mattress. For the weight class from 70 kg I would highly recommend this mattress definitely. I found the mattress in this price range very pleasantly surprised and I do not want to miss!
