Please ID this chair design

I have bought this interesting chair from a second hand shop in Romania. They usually bring furniture from Germany and UK. I really like the design of this chair and I am asking you to please help me identifying the designer or the brand.
The chair has solid wood leg frames and curbed plywood back and seat. The turquoise frames might have been painted afterwards, because the underframe is unpainted and has dirty paint spots.
There is no mark, label or any other sign indicating a source of origin.

I have searched the internet but the closest match is a Heinz Witthoeft design (http://www.artnet.com/artists/lotdetailpage.aspx?lot_id=1189F7CCD22C92779E7E5FB6624C42E1) from the 50's with quite a distant resemblance.

It may be an old Ikea or similiar item of furniture, or a really valuable piece of MCM Design. However, the chair is very comfortable and I intend to use it for my home office.

Thank you very much and please be gentle, as I am a newbie on this forum.

I love it...let me know if you manage to identify the designer or brand!
