How to build a cooler bed for under $200
A cooler bed is a stack of small fixes in the right order — and the first ones are free. Here's the sequence, with the evidence for each layer.

What comes before spending anything?
Airflow and timing: cross-ventilate in the evening, run a fan for moving air across the bed, and keep afternoon heat out of the room in the first place. Then audit the duvet — a winter-weight duvet in summer defeats every fabric decision made underneath it. These steps cost nothing and move the needle more than any single purchase below them.
Where should the first real money go?
The fabric layer — sheets and pillowcases in a breathable natural fibre, percale for crisp or sateen for smooth. It's the layer touching the most skin all night, the physics is measured rather than promised, and done well it fits comfortably inside a modest budget, especially bought on promotion. Our roundup ranks the sets we've assessed, first pick's hundred-night trial included.
If budget remains, finish with pillow geometry: right-height beats right-brand in the clinical evidence, and our loft guide turns that into a tape-measure job before you spend anything on plumpness.
What shouldn't be on the list?
Anything promising degrees without a method, anything 'cooling' woven from the fabrics that measure worst at moisture, and anything bought to treat drenching night sweats — which the NHS files under see-a-GP, not shop-harder. A cooler bed is a comfort project; the moment it's a symptom project, the checklist changes and we'd rather tell you that than sell you fabric.
