Chairs
We most commonly see the "Wingback Chair," which comes in a few different styles. Most modifications are the size of the wings, the overall bulk of the piece, and the type of cushion (internal cushion, tee-cushion, or basic square cushion). In most cases, the latter two are boxed with welt/piping.
The type of cushion will impact the amount of yardage used, as well as the layout, if a pattern is required. Occasionally a skirt is added, though it is not common. For chairs without a skirt, we recommend allowing for 8 to 10 yards, depending on the style of the chair, and whether a pattern is required. Every fabric store has a yardage chart (click here for yardage chart). 
The most common chart has been handed down from the 50s, depicting yardage estimates that are insufficient for today's furniture, and may vary depending upon the type of amenities, and fabric that may apply.
Having a qualified upholsterer inspect your furniture to give you an accurate estimate of how much material you may require is best, and to address any unforeseen work that may arise. For quoting purposes, we invite you to email digital photos (seeing a couple of angles of front and side profiles is helpful, and include dimensions) to info@graymatterartsandcrafts.com. We will do our best to reply within 48 hours.
The second most distinguished style in an upholstered chair is the "occasional chair." Built for comfort and relaxation, you may choose from a large variety of styles, ranging from the traditional Tudor style with a skirt, to the oversized conventional type with large rolled arms and humongous back pillows. Getting a hands-on quote is usually best, since many intricate details are associated with them.
The remaining range of chairs consists of various types, from the ordinary dining room chair, or a Martha Washington, to Louis XV armchairs, (see chart for descriptions). Be sure to indicate whether your piece is an antique; the method of upholstering applied may differ, and will impact costs.
