I've found some great sheet (by feel) at places like BB&B, but we have a split king
And none of those nice ones have just a fitted full that I can buy that matches with the King flat.
We have 10 pillows. I get 2 at sleep time. The wife makes a full-on fort like enclosure, often has to literally jump to get in the middle. And then doesn't move. 4 of the 10 are the Sobakawa-type filled with buckwheat. If you want a pillow that stays cool, you want a Sobakawa.
