Barcelona chair made by Thonet  

Hi. I am not really able to help you dating the chair but Eclair is a French brand of zipper that started in 1924 and still exists today. I have no clue if they exported a lot abroad but here it is a rather famous brand, to the point that a zipper is commonly called

You need to look at examples made by Thonet (also Thonet Freres) from a design museum in your area or a dealer/auction house that currently has a period example to compare details with your chair.

The example at the Cooper Hewitt Museum in New York USA is an older example made by Josef Muller/Berliner Metallgewerbe from 1929 & if you look at the images, the frame shows a lot of age.

The elevation drawing is by Mies Van Der Rohe from the Museum of Modern Art NY.

Realized that this is not a pre war chair, I just believe the stories from an "expert".

Anyhow, I would really appreciate if anyone can tell me more about this chair. Some details I found (there're more):

- Frame is magnetic and bolted with hex flat head. The joints are hidden under straps.

- Back Cushion are following the arc

- 8/9 leather straps. "Raw" side towards cushion.

- "Eyelet"/loophole in each top corner of seat straps to fasten cushion

- latex foam

- leather straps fasten in frame with screws (no washers or rivets). Notice how they aren't in a straight line due to the construction of the joint.

- 75cm W x 76cm D x 76cm H(with cushion).

- the zippers from eclair wasn't produced before 1948 according to the company itself.

- I also got the ottoman (cushion and "eyelets" in pictures)

I got an opinion that this can be a France, U.K. or German made version from late 50/60s. The all differ from each other's and US.

What do you think guys?

Thanks
