Having the Dunlopillo mattress a month, I can only say that I would highly recommend this Matratzte unlimited. She has the right hardness for me and allows a restful sleep. Back problems do not exist. In addition, it is easy to handle, contrary to my pocket spring mattress that I had before. The price pleasantly surprised me, because you get from Amazon for less money than in trade a high-quality mattress. The delivery was prompt and trendy appointment. I have this Internet order, no regrets despite previous skepticism.
