Furniture is stuff that helps us sit down or lay on, and keep our things in. It can be big, like a bed or sofa, or small, like a table or chair. Different types of furniture are made of different materials like wood, metal, plastic or fabric. Some furniture can be built really easily, like a bookshelf you put together with screws and bolts. Other furniture, like a sofa, can be really hard to make and need lots of special tools and skills. We use furniture every day to make our homes and offices comfortable, and to help us work and relax.
