"The Bigjigs range is made in a number of different factories all over the world. Most are based in the Far East but some are still in the UK and Europe. Less than 30% of the items that we stock are manufactured in China.
The Santoys range is all made in Thailand, the Heimess range of baby products is made in Germany and the Larsen range of puzzles is made in Norway."
Working conditions in Thailand generally may not be much better than China, but Plan sells itself as a sustainable/ethical company, and seems to do quite well in assessments on the Ethical Consumer website, which has labour conditions as one of its assessment criteria: ranked fourth for cars and trains and second for dolls. (I have no connection to Plan, btw - just bought quite a lot of their toys while living in Asia; they are harder to find here, I think, but Amazon stocks some.)
We have this game too which is not quite a jigsaw, but lots of fun. You can make your own buildings, or make the ones they supply as pictures (i.e. try to copy their designs- good for young children to develop skills).
Sylvanian Families are created and developed by Epoch Co. Ltd, a Japanese toy company based in Tokyo. Physical product manufacturing takes place in China.
Have emailed Born Direct about their Brio stuff. I understood Brio manufactured a lot of stuff in China and hadn't got great work standards. Video about the factories toy companies like Brio use However this is from 2004, so they may have changed their ways since then?
