A bed is a soft, comfortable place you sleep at night. Beds usually have a pillow to rest your head on, and sheets and blankets to keep you warm.
The girl in the picture is lying in bed under a blanket. Blankets are big, thick, warm pieces of cloth that you usually have on your bed. Many people knit or crochet blankets.
A clothes hanger, or coathanger, is a triangular object with a hook at the top that you use for hanging your clothes up inside a wardrobe. Coathangers can be made from wire, wood or plastic.
A mosquito net is fabric with holes woven into it that lets light and air through but keeps mosquitoes and other insects out. Mosquito nets are commonly seen draped over beds, to keep people from being bitten when they are asleep.
A pillow is a bag stuffed with something soft. Unlike cushions, pillows are all around the same size. Pillows are for putting your head on when you are asleep at night time. You usually have at least one pillow on your bed.
A quilt is a kind of blanket that is made from layers of fabric stitched together. The top layer is made from scraps of fabric made into patterns or a picture. Quilts used to be a good way to use up leftover bits of fabric, but in modern times people make quilts as a hobby using new fabric in the colors that they want.
Sheets are large, thin pieces of fabric that you put on your bed. Usually there is one sheet covering the mattress and another over the top of that one. You sleep between the sheets.
