Are you in the US? It looks American to me---the oak and the parts being flat boards rather than pieces turned on a lathe. Still, it has a bit more flare and grace than a lot of American furniture in the Danish Modern style. American furniture was often not marked on the frame---maybe it was marked on the original cushions.
The cushion may be something someone stuck on there from some other piece of furniture. People do stuff like that pretty often. When you measure for new cushions, be sure to subtract the thickness of the seat cushion from the height of the back since the back cushion will rest on the seat cushion. Back cushion height is usually somewhere between level with the top of the frame and 1/2" to an inch higher. If you like to sit with your arm draped over the back, go for the higher measurement so that it's more comfortable.
The plywood seat was added. Restoring it to whatever kind of webbing was on there originally will make it more comfortable and it's usually pretty easy to do.

Was it missing the arms when you bought it? I think it's definitely American also. Probably a mid level/low level manufacturer that wanted to make an affordable Danish style furniture.
