The comforter can trace its origin to the quilt. The quilt, in turn, can trace its origins nearly to the beginning of mankind's history when man sought to cover himself with animal skins so as to keep warm. When people learned about fibres, these coverings started being made of loosely-quilted linen and other fabrics. The present-day comforter is stuffed with poly batting, silk, feathers, cotton, and other materials. Be careful when buying a cheap comforter set.
The fabric of the cheap comforter set needs to be considered. Fabric which are used in the making of the set can include polyester, cotton, cotton blends and linen. Wool comforters are possible, but the wool would probably not extend to the sheets. Check the fabric content of the set. If you have sensitive skin, then you would probably not want to have polyester or polyester/cotton blends. The cotton will be of different levels of quality from low count (threads per square inch) to higher thread counts. The high thread counts can mean a softer sheet. This can be a consideration when shopping for bedding and for a comforter. Another cotton fabric to be considered is jersey. It is knit instead of woven. The fabric is soft like a T-shirt, though it can stretch.
The thickness of the stuffing
The thickness of the stuffing in the comforter can be an indication of the quality of the comforter. This is something to be considered when looking through cheap comforter sets.
Thicker comforters may be more expensive unless you can get them on sale. If they are excessively cheap, check the fabric content as well as thread count to learn why
(it may just be a matter of a discontinued pattern). If the comforter is stuffed with down and it is very cheap, then the comforter may be stuffed with down from China. This type of down may be of a less better quality than other downs.
The quality of the comforter matters. If a comforter set is well sewn, is made with good fabric, is fairly thick and it is still cheap, then check the stitching on the comforter. If the stitching is sloppy or the stitches themselves are long, then there is the risk that the comforter may not last. Paying a little more for good stitching could mean the difference between a comforter set that will last for years and one that may have to be replaced sooner than you would like. Do not forget, if you get tired of a pattern, you can always cover it with a duvet cover. If the comforter falls apart, you will not have as many options.
