Otto Keller’s duvets are of highest quality: filled with pure feathers and downs according to the standard of DIN EN 12934 and covered in 100% cotton fabric. Most commonly duvets come with boxes and can include baffles of various heights to determine the degree of insulation of the comforter. Each single compartment is filled individually to prevent feathers and downs from shifting. Cold zones are therefore completely eliminated.
The standard sizes of the duvets are 135cm x 200cm,155cm x 220cm, 200cm x 200cm. However, due to our own sewing department, duvets can be individually manufactured to any desired size and form including Karostep, box-square duvets or four-seasons comforters.
