IKEA has several down comforter offerings that are just genius.  Noted as “1+3,” they are lightweight and medium-weight comforters that are sold as pairs.  If you just need a little bit of coverage, you can use the lightweight comforter–rated a “1” on IKEA’s temperature scale.  Needing a little more warmth?  Use the medium (“3”) comforter, solo.  When it gets super chilly outside, snap them together to create a heavier duvet.  It’s like a BOGO deal.

Also?  Their king size comforters actually fit a king sized bed…which is more than I can say for a lot of “king size” bedding out there on the market.

Prices range from $69.99-$149 for full/queen size and $79.99-$169 for king size, and are available with down and down alternative fills.
