Thanks for the help! I managed to undo the wrong figures!
I have just now a family with a child and they told me it is more than o.k. with the sofa for their son.
Thanks again! As for bedding I was astonished to read how the beds are prepared for the guests from some hosts. My bedding is done in the Ameriacan way - even more - 2 protectors for the mattress, a sheet, then a special fitted sheet with elastic on the edges and from elastic material - not needing ironing, then another sheet which is changed for each guest.
I use winter and summer duvets, and I have covers from sateen cotton for them, and I have special ones from down - for heavy winter days or cold spring or autumn days when the central heating is not yet on.
I always iron all kind of sheets as this is the only relaiable way for desinfection!
