Chair covers can be purchased to fit almost any type of chair from dining room chairs to recliners. So you have to know what type of chair you are buying the chair covers for before you begin to shop.
In order to get covers that will fit your furniture correctly you need to get a measuring tape to measure the piece of furniture with. You will need to take several measurements in order to get.
You will need to measure the height of the piece of furniture. You want to know how far the seat of the chair is from the floor. You do not need to include the height of the back of the chair when measuring the floor height.
You will need to measure the width of the seat on the chair to determine how big around the cover must be. You will also need to measure the piece at its widest width. The arms of the piece may increase the width of the cover by several inches so take this into consideration when measuring.
You must measure the height of the chair back. The back of the chair will be several inches taller than the seat of the piece and you will need to know exactly how tall it is.
Write all of the measurements down so that when you are shopping for your covers you can refer back to these notes and will likely order a better fitting piece.
When you are shopping the type of cover will make a difference as well. Some covers are made to be draped over the chair like a blanket thrown over a bed, while others are made to fit the contours of the chair.
You should look into the material that the covers are made from. Some materials have more give to them than others do. That means that some materials will stretch a little and cover something larger than they are. Read the labels to see if the material the cover you have chosen is made of has a high level of elasticity.
