The quilt cover is a household thing, unlike furniture, which can be used for a long time. Although the quilt cover pays attention to quality and can be used for many years, it needs to be replaced regularly. When choosing the fabrics and materials of bed sheets and quilt covers, brand products have more advantages, and bed sheets and quilt covers belong to the 24th category in the trademark classification of bedding products. This is a common classification standard in the world, and it is also applicable to Chinese trademark registration. Category 24 mainly covers products related to bedding, including sheets, quilt covers, pillowcases, blankets, duvets, pillows and mattresses.
