Materials: Plastic Furniture

Arguably the world’s most ubiquitous man-made material, plastic has impacted nearly every industry. In contemporary spaces, new and vintage plastic furniture is quite popular and its use pairs well with a range of design styles.

From the Italian lighting artisans at Fontana Arte to venturesome Scandinavian modernists such as Verner Panton, who created groundbreaking interiors as much as he did seating — see his revolutionary Panton chair — to contemporary multidisciplinary artists like Faye Toogood, furniture designers have been pushing the boundaries of plastic forever.

When The Graduate's Mr. McGuire proclaimed, “There’s a great future in plastics,” it was more than a laugh line. The iconic quote is an allusion both to society’s reliance on and its love affair with plastic. Before the material became an integral part of our lives — used in everything from clothing to storage to beauty and beyond — people relied on earthly elements for manufacturing, a process as time-consuming as it was costly.

Soon after American inventor John Wesley Hyatt created celluloid, which could mimic luxury products like tortoiseshell and ivory, production hit fever pitch, and the floodgates opened for others to explore plastic’s full potential. The material altered the history of design — mid-century modern legends Charles and Ray Eames, Joe Colombo and Eero Saarinen regularly experimented with plastics in the development of tables and chairs, and today plastic furnishings and decorative objects are seen as often indoors as they are outside.

Find vintage plastic lounge chairs, outdoor furniture, lighting and more on 1stDibs.

    To identify vintage glass, you will need to figure out if your item is between 20 and 99 years old. The easiest way to do so is first to determine the maker by looking for and then researching any markings present on the glassware. Unfortunately, vintage glass is often marked with paper and foil labels, which tend to come loose with use. As a result, experience and expertise are often necessary to accurately perform the identification process, so you may wish to have a certified appraiser or experienced antique dealer weigh in if your glassware is unmarked. Find a diverse assortment of vintage glassware on 1stDibs.

    Yes, some vintage glass is worth something.

  • 1stDibs ExpertOctober 24, 2024
    To tell if your vintage glasses are gold, look on the nose bridge and the temples for a purity mark. Makers often stamped their solid gold pieces with “12K,” “10K,” “14K” and other markings to identify their gold eyewear. You can research all of these markings using trusted online resources. Should you locate a "GF" mark, it is likely that your glasses are gold-filled rather than solid gold. This means that the frames are predominantly a less expensive metal but do have a thin layer of genuine gold alloy as a finish. Another mark that indicates your glasses contain some gold is "RGF." The mark stands for “rolled gold filled.” Glasses bearing this mark feature a gold-plated finish that is thinner than what's found on traditional gold-filled frames. For assistance identifying your eyeglass frame material, consult a certified appraiser or experienced antique dealer. Explore a selection of vintage glasses on 1stDibs.
  • 1stDibs ExpertNovember 2, 2023
    To tell if vintage Cartier glasses are real, first look for the brand's logo on the outside of the arms. It should be spelled correctly and in the French luxury fashion house's iconic gold-toned italic font. Because some vintage pieces may lack serial numbers and other markings used to identify contemporary eyewear, you may wish to enlist the help of a licensed appraiser or knowledgeable dealer for assistance with authentication. Explore a selection of Cartier glasses on 1stDibs.
  • 1stDibs ExpertApril 5, 2022
    The easiest way to tell if a bead is glass or plastic is to feel it. Glass beads will be cooler to the touch, whereas plastic beads will be closer to room temperature and warm up quickly in your hands. Another test you can perform is to listen to the sound. Glass has a distinctive ring since it’s harder whereas plastic is softer and has a duller sound. Shop a range of vintage glass bead pieces on 1stDibs.
