I am selling a Magnetic Matress Kemko (Infra-Vermelhos), you can find information on internet about this japanese technology, it is really good for people who wants to take care about their column. The matress is very firm.
It is as new, with 9 years warranty, i have the invoice ( Protected content ), and i am asking only Protected content for it.
I repeat, it as new, I used it only a few nights and moved to a place where i have a queen bed now... I bought the same technology and it makes a real difference, i no longer have back-aches during te day.
Send me an email to Protected content if interested, I have pictures and more details.
It is located in VIla Olimpia, you must take it here.
PS: Open to trades (bike, TV, electrodomestic stuff,....).
