I was amazed when I started living here in Sweden, that I found most of my friends with 2 duvets on their bed, instead of one large one. They sleep together, but under 2 seperate duvets. I found it very perculiar indeed.
In South Africa you have 4 main sizes. Single, Double, Queen and King. When I decided to enquire here, most of the shops, IKEA included sells mostly single duvets and single covers. In South Africa when you grow up you do so on a single bed. Then you start studying and might move into your own apartment, plus your girlfriend might stay over every now and then, so you move up to a double or if you're lucky, a queen size bed. When you get married it's definitley a Queen, but possibly a King size bed. It's how it is... and matching size duvets to match the size of the bed.
I am 1,92m tall and I like to tuck in my feet and my shoulders a the same time when I go to bed. Like a mummy perhaps. How can I do that with a single duvet that's 1.80m in length. It doesn't work.
How can I hold my partner in the middle of the night and not have the cold air come in somewhere between the two single duvets?
Fortunately for me, my partner and I met in South Africa, and started our relationship under a King size duvet. 2,20m x 2,30m. That's plenty of duvet for tucking in all the parts, and holding and cuddling if you ask me. So when we moved to Sweden, we had to go and hunt for a King size duvet, because it's not a very popular size. And when you enquire about it you get this weird look of "what's wrong with you? can't you be luck everyone else and just sleep under a single duvet?" But we finally found one and now I am happy again, because I just couldn't fall asleep with my feet sticking out, no matter how hard I tried. And it's got nothing to do with being scared about the monsters under my bed.
I can imagine that it's never really cold indoors, so you don't really feel your parts outside the bed at night. We don't have central heating in South Africa, so it can get cold inside too, maybe that's why we all need to tuck ourselves in at night.
So I would like to know what the traditions are where you come from, but specifically why in Sweden they have 2 duvets?
