Transport and Storage of Mid-Century Furniture: A Matter of Care
An original sideboard from the late 1950s, a lounge chair with aged aniline leather upholstery, a delicate rosewood dining table: such pieces have survived six decades because they were built with precision craftsmanship and because their owners cared for them in everyday use. The most critical moment in the life of a vintage piece of furniture is rarely its daily use, but rather the change of location: moves, interim storage, international transport. Veneers come loose when humidity and temperature fluctuate, mortise-and-tenon joints shift, and upholstery takes on permanent deformation. Those who collect Mid-Century design therefore treat transport and storage as part of value preservation, not as a logistical footnote.
The following sections outline what matters in terms of materials, which regional construction styles require special consideration, and how to recognise at the point of purchase whether a piece has been handled professionally. The aim is not an exhaustive restorer’s manual, but a precise look at the points where collector quality is determined.
1. Characteristic Materials and Their Climatic Requirements
The dominant woods of the era behave very differently. Teak, as favoured by Danish workshops of the 1950s and 1960s, is considered comparatively dimensionally stable due to its high natural oil content, but is sensitive to localised heat and dry central heating air. Rosewood, in particular Rio rosewood (Dalbergia nigra, listed in CITES Appendix I since 1992 and thus strictly trade-restricted), is denser, more brittle and prone to hairline cracks in the veneer under significant climate swings. Oak, walnut and maple, as frequently used by American and German manufacturers, move more across the grain and require constant relative humidity.
As a guideline for storage and living conditions, 45 to 55 percent relative humidity at 18 to 22 degrees Celsius is recommended. Values below this, as regularly reached during heating periods, lead to shrinkage cracks, detached veneer and open joints. Values above this promote mould and metal corrosion on fittings. For transport, this means: no unheated storage halls in winter, no uninsulated containers in summer sun, no positions directly against exterior walls or above underfloor heating.
Upholstery deserves its own attention. Cold foam, latex and the horsehair or coir fibre inserts typical of the era react differently to pressure and moisture. An armchair that is stacked for months loses its resilience; original coverings of wool, linen or aniline leather absorb odours and moisture. During transport, upholstered furniture should stand upright and individually in breathable cotton covers — never in plastic film over extended periods.
2. Regional Schools and What Their Construction Means for Handling
The Danish cabinetmaker furniture by Hans J. Wegner, Finn Juhl, Arne Vodder or Kai Kristiansen is designed around precise wood joints. Dovetails, concealed tenons, conically screwed legs: much of it is dismantlable and should be dismantled for transport. Round table legs on dining tables and sideboards are traditionally screwed into recessed threaded plates and are the most common breaking point when a piece of furniture is transported lying down without removing the legs.
American classics from the circle of Charles and Ray Eames, George Nelson or Florence Knoll frequently combine plywood with metal and rubber. The shock mounts on the Eames Lounge Chair and Plywood series are aged rubber and can tear under sudden stress. These models should be transported seated and secured, not lying on the backshell.
Italian modernism by Gio Ponti, Ico Parisi or Osvaldo Borsani often works with brass, lacquered metal frames and marble. Marble tops are transported exclusively upright, on felt pads, never stacked flat. German post-war designs from the Ulm and Braun circle, as well as production furniture by Knoll International Germany or WK Möbel, frequently rely on plywood constructions with exposed edges that are sensitive to impact and require edge rather than surface protection.
3. Authenticity and Condition: What Collectors Should Look for When Purchasing
A carefully transported and stored piece can be identified by several details. Veneer edges are closed, without raised chamfers; drawer runners operate smoothly; mortise and tenon joints show no gaps of more than one millimetre. On seat surfaces, check the resilience of the upholstery and the tension of webbing or springs. On rosewood and teak surfaces, a matt, even patina indicates well-maintained storage, while dull spots or white rings point to moisture damage and unsuitable locations.
Provenance and marking are the second test. Original brand stamps from Danish control marks (such as the control stamp of the Møbelfabrikanternes Kontrollforening for Massivmøbler, abbreviated FDB control stamp, or the Dansk Møbelkontrol mark), manufacturer marks from Fritz Hansen, Carl Hansen & Søn, France & Søn, Herman Miller, Knoll, Cassina or Tecno and documented invoices increase attribution certainty. For CITES-relevant timbers, particularly Rio rosewood, a pre-acquisition certificate (pre-convention proof) is required for cross-border trade.
Restorations are not a flaw if they are carried out professionally and reversibly and communicated openly. Reupholstered cushions with period-appropriate textiles, refinished surfaces with oil rather than thick lacquer, and replaced webbing keep a piece functional. Critical, however, are sanded-down veneers, thick new lacquer coatings and replaced original fittings that irreversibly alter the substance.
At mid-centurydesigns.com, we examine every piece before it enters the inventory for construction, material condition, marking and provenance. Transport and interim storage take place in climate-controlled spaces; packaging and shipping are guided by the structural characteristics of each individual model — from the demountable table base to the lounge chair with aged shock mounts. This way, you receive a piece of furniture in the condition its documentation promises.
