i would like to buy a new bed as well. Have you heard for Vi-spring beds? Belgium company. i heard that they are also made from natural materials and the best in the world? they are also quite expensive. do anyone have any comment? comparisson? i am quite confused with the wide variety of the products and all are the best:) I was impressed by Vispring what are have read on their website and what i read in the catalogue they have sent it to me but i have not tied slipping on this bed. they have also cheapest versions of the matresses. but whether thea yre also so good as the best models? is it enough to buy just a matress and not the entire bed? i would appriciate any comments, experiences. Unfortunatelly neither of the brands you have talked and i am talking is not sold in my country, so i can not try personally.
