Bed heads: choosing a mattress for comfortable winter hibernation 

Lie back, breathe deep and enjoy Kya deLongchamps's advice

The circadian rhythm is the healthy, natural clock buried in the mind that keeps us healthy. 

When you’re sharing rollicking centimetres from head-to-toe, and side-to-side, the territory of a bed becomes a high stakes matter. Combine those dimensions with the dynamic sleeping habits of adults — the star-fish, the sprawler, the crawler, the spooner, the thrasher and the edge clinger — there’s a lot to bed down here.

I have a 6’5 partner and a super-king bed. Ex-army, he sleeps with a balled pillow on the seam of the bed, with one foot on the floor. I can’t find him with a fully extended leg unless I buttock-hop to the centre. As with anyone stabling a Super-King, I’ve learned to ferret at the very bottom of sheet shelving in-store too, and have accepted I will be largely disappointed.
