Ready-to-assemble furniture

Ready-to-assemble furniture is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Ready-to-assemble furniture rather than just read about it. In short: Ready-to-assemble furniture (RTA), also known as knock-down furniture (KD), flat-pack furniture, or kit furniture, is a form of furniture that requires customer assembly. The separate components are packed for sale in cartons containing assembly instructions and sometimes hardware.

Key takeaways

  • Ready-to-assemble furniture belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Ready-to-assemble furniture to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Ready-to-assemble furniture from memory before moving on to harder problems.

Reference excerpt

Ready-to-assemble furniture (RTA), also known as knock-down furniture (KD), flat-pack furniture, or kit furniture, is a form of furniture that requires customer assembly. The separate components are packed for sale in cartons containing assembly instructions and sometimes hardware. The furniture is generally simple to assemble with basic tools such as hex keys, which are also sometimes included. Ready-to-assemble furniture is popular with consumers who wish to save money by assembling the product on their own. Producers and merchants benefit from selling ready-to-assemble furniture, because furniture is bulky once assembled, and thus more expensive to store and to deliver. Since the assembly work is done by the consumer instead of by the manufacturer, its price can be lower. A furniture assembly service industry has developed, making it easy for consumers to employ someone knowledgeable to assemble their furniture for them. Produced mainly from particle board or medium-density fibreboard (MDF), the cost of producing this type of furniture is cheaper than using solid wood. The low grade timber is coated with a polymer laminate to replicate various types of wood, allowing a high-quality-looking finished product.

History

Ready-to-assemble furniture has roots that extend back a long way, as cabinetmakers have been making furniture that is easy to disassemble for transport for centuries. The New American Cyclopaedia of 1859 listed the assembly of furniture as an "American invention" that emphasized ease of transport, but this claim is rather vague. A better claim to the earliest RTA furniture is the Thonet No. 14 bentwood chair, which was specifically made to be easily disassembled to save space during transportation. It was first produced in 1859. Slightly later there is an American patent of 1878 that defines some prefabricated furniture as follows: "The invention refers to a class of furniture in kit to be packaged and transported in pieces and assembled by specialized and unqualified people." An early attempt at a business selling RTA furniture was set up by designer Louise Brigham and two partners during World War I. By 1915, Home Art Masters was offering RTA furniture kits at moderate prices through a mail-order catalog. The buyer received a set of parts that the company stated could be “quickly put together and finished. Everything including instructions, furnished. A boy or girl can set it up.” Home Art Masters was short-lived and it is uncertain how many of their RTA furniture kits were ever sold. The next experiments in running an RTA business stem from the 1940s and 1950s. In the late 1940s, the Australian designer Frederick Charles Ward founded a mail-order RTA furniture business because he was disturbed by how little affordable furniture there was for people of modest means. Lena Larsson helped to create one of the earliest Swedish brands of ready to assemble furniture, the TRIVA line, for Nordiska Kompaniet in 1943. In 1953, the Ohio cabinetmaker Erie J. Sauder received the first U.S. patent for RTA furniture for a table that could be assembled without either hardware or glue; he called it "snap-together" furniture. In the Scandinavian countries, the furniture kit may have been independently invented by Swedish technician Gillis Lundgren, who had the idea when trying to transport a table in his car. According to reports, he had to saw off the table's legs so he could put it inside the car and take it home. He talked about the idea with his boss at IKEA, and IKEA started selling flat-pack furniture in 1956.

Worked examples

Example 1 — a first encounter with Ready-to-assemble furniture

Start with the simplest possible case. Write down what Ready-to-assemble furniture claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Ready-to-assemble furniture before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Ready-to-assemble furniture ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Ready-to-assemble furniture

In research
Ready-to-assemble furniture appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Ready-to-assemble furniture in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Ready-to-assemble furniture is common in secondary-school and first-year university syllabi. It links to neighbouring topics DIY culture, Flatpack furniture, Furniture, so understanding it makes those chapters shorter.
In everyday life
Look for Ready-to-assemble furniture outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
