Who likes his mattress so as I -> most supple as ten-year-old concrete having here with this sure his joy. However, I really recommend it only people who normally sleep on stone floor and / or heavy as a small car. I for one would not want to miss this mattress in my life, and will also today my old mattress with a fitted sheet, a plated, 20 cm thick styrofoam board disposed of with a clear conscience !! Perhaps I order even a 2nd mattress for my judo exercises. The normal judo mats are me this little too soft!
5 stars for this hard piece of convenience! ;)
