If you have a corner breakfast nook set then you might be considering cushions for your L-shaped bench. You could just line up several chair cushions along the benches that are meant for other styles of nook sets, but there are special cushions made especially for the corner bench. They usually consist of either two or three pieces. They come in many different prints and fabrics and they give the corner nook a more sophisticated feel.
Some corner nook cushions come in two pieces. Generally a corner breakfast nook bench has a long side and a short side. When there are only two pieces to the corner cushion set then there is one cushion for the short side that extends from the edge of the short bench to the back of the longer piece. Then there is a second cushion that extends from the edge of the long bench until it meets the cushion from the short end. This style only works if your bench does not have a curved corner or a corner that has a back at an angle. These cushions will only sit correctly if the L-shaped bench is completely square in the corner.
The second and more popular variety of corner nook cushion sets is three piece sets. With the three pieces set there are rectangular cushions for the short and long bench pieces and then a special corner cushion that looks a little like a pie piece to fit into the corner bench seat. With both varieties it is important to measure you benches carefully to make sure that the cushions will work. You do not want sections of cushions falling off of the end because they are too long.
If you cannot find corner nook cushions the correct size for your breakfast nook then you can always make some. The procedure is similar to making a pillow or chair cushion, the dimensions are just larger. You can look for instructions online or find a local crafts store with weekend classes. Another alternative is to hire someone to custom make your bench cushions.
