Dating age antique furniture
Sometimes style is enough to tell how old a chair is, especially if that style was only popular for a short time.
For example, an olive green recliner with yellow or orange flowers is most likely from the late 1960s to 1970s, as that type of print and color combination hasn't come back into fashion -- yet.
If the screws look newer or the style of the hardware differs from the style of the rest of the piece, the hardware is no longer a good indicator.
The hardware on your furniture can be used to date the piece, providing it is original hardware.
You should have a discernible amount of difference between the two measurements. By the nineteenth century, cabinetmakers were using several smaller dovetails to join together the sides of drawers. If each dovetail is the same size and evenly spaced, they were crafted on machinery.
This puts your piece into the Victorian era at the earliest.
The wear and tear of a piece of furniture also helps to tell its age.
The condition and quality of materials are used to gauge the age of a piece.
In the 1900s, synthetic materials such as upholstery foam and fiberfill entered the scene.
Identifying the material stuffed into seat cushions helps identify a chair's age, but it's possible a chair was revamped somewhere along the way, with the original seat padding exchanged for updated fillers.
Likewise, mid-century molded fiberglass chairs -- popularized by Charles and Ray Eames paired with manufacturer Herman Miller -- still influence plastic chair design, yet are distinguishable by their thin metal legs and noticeable fiberglass fibers.
Look at images of chairs similar to yours online if you are unsure when your chair was manufactured.
Modern upholstered chairs may feature a tag listing both manufacturer and serial number or design name, which can be looked up on the manufacturer's website or on collector websites.
