I'm waiting for sleeping in hammocks to catch on here. Soon, there'll be an article espousing easy summer sleeping and the more vertical position making for easier breathing. I do sleep in one but it'll be funny to see.
In case anyone reads this:
One of the best things my wife and I have done in the past year was to switch to each of us having our own set of sheets. It's amazing. Highly recommended.
Do you have two twin mattresses side-by-side, each with its own set of sheets?
This is probably only feasible because we sleep on the floor, which means the blankets don't tend to wander in the night.
Lots of covers stealing other blanket shenanigans have been avoided in the past year though from that change.
