I don't know who has made the rocker itself, but I know that Mettes grandmother made the upholstery. So I guess that once you could buy those rockers and finish them yourself.
There are a lot of similar old rockers for sale in Denmark, so maybe a company produced them, or you could make one yourself using a set of drawings.
I have seen a little variation in how the legs are attached to the lower platform, but apart from that they all sport a lot of bulbous turnings everywhere.
I would like to make a newer version of this chair, without all those decorative turnings. My chair should also have a curved lower platform, where the platform ant the actual rockers were mirror images of one another. The back should sort of flow from the rockers instead of being planted like it is on the old chairs. The armrests should also be a bit more integral
A fine thing about this idea is that the rocking motion won't mar the floor and the rockers can be kept fairly short, so the chair don't take up that much space.
The chair is comfortable to sit in, so it is just the design I don't completely agree with.
Danish type rocker, matching stool next to the door.
