Oh, I love Muji. They need to open up a store here in the Netherlands 
Some other affordable brands that sometimes have nice design items for in the home are Umbra, Koziol, Joseph&Joseph (love the Y-shaped pepper mill I got), and Kikkerland. In my experience the quality is good. It’s just that for many of these brands’ items they’ve tried a bit too hard to give it a design or some fun aspect and then it just doesn’t work anymore for me, but some products are lovely.
