The mattress is by the Nano Cell foam core also pleasantly light, which has nothing to do with the old spring mattresses. Despite the low weight of the foam core for high strength and dimensional stability ensures. The already very high service life of such mattresses can be increased by regularly twisting and turning yet. Very good I find the suitable for people with allergies removable cover made of cotton fiber and air, which can be washed at 60 degrees. This ensures good hygiene over the lifetime.
I sleep now since three weeks on the mattress and am completely satisfied with this. If you change the mattress, there are always at the beginning of a brief period of getting used to. I switched from a cold foam mattress on this model and had me two nights to get used to it, that this model is much stronger than my current mattress. But since then I sleep it wonderful.
This mattress is of good quality processed and made of quality materials. It is hypoallergenic with washable cover, breathable, adapts to the body shape while sleeping just fine and has a very good value for money. Since you can not go far wrong actually. From me there's anyway 5 stars for this mattress.
