Best thing my wife and I ever did was having separate quilts (same bed though). Means we have independent heat adjustment, since we're like frosty vs surface of the sun at night.
This is common in Norway. I discovered this from my Norwegian partner and it's the best thing for comfortable sleeping. The only problem is my partner discovered all-in-one quilts as standard in Australia and thinks all-in-one is the best thing ever.
A giant heavy doona is pretty comfortable itself though!
What is an all-in-one-quilt? It sounds awesome.
I assume they just mean a non-separate quilt.
Correct - a standard full size doona (Aussie for quilt)
