only I never thought back a sheet without rubber edge, then there were situations when visitors came u.ich my sofa bed had to move out, where to put the rubber. So I decided on this sheet without gum u.bin very zufrieden.ich use it even if no visit there, then I put it across the beds u. it looks best from u. fulfills its purpose, because the sweat goes only u.man sheets on the one does not have to deduct always two sheets.
