Rock 7 by Hironori Tsukue

Japanese designer Hironori Tsukue has created a set of rockers for the Seven Chair, designed by Arne Jacobsen in 1955 and produced by Fritz Hansen.


Manufactured in white, lacquered birch or natural, lacquered ash, the rockers slot onto the chair's legs without any fixings.

The following text is from Hironori Tsukue:


For several years, I have been an owner and user of the "seven chair” by Arne Jacobsen / Fritz Hansen. I use this chair every day as my working chair. I prefer this one to any ordinary high-tech office chairs. I also believe it looks much better in my home environment.

Unfortunately the sitting height is a little bit too low for an office chair. Therefore, I would like to present my solution to this problem. My idea is to add metal pipe legs to the original chair. Apart from obtaining a perfect height, different ways of sitting will be possible - to sit in different angles helps to reduce monotonous pressure on your body.

I believe this new working/rocking chair would be a nice alternative office chair, possible to use in offices as well as private homes, cafés, restaurants, public libraries etc.

The rocking parts are packaged in a small box, easy to buy and attach to the original ”seven chair” without any tools.
