Bedding

Bedding is where the marketing is worst

Mattress marketing at least has physics to argue with. Bedding marketing has thread count — a number that has been so thoroughly abused that it now tells you almost nothing about the sheet you're buying. If you take one thing from this section, take this: fibre and weave decide how a sheet behaves. Everything else is packaging.

The thread count lie, briefly

Thread count is threads per square inch. It stops being meaningful at about 400, and above that it's usually being inflated on purpose. The trick is multi-ply yarn: take a thin, weak thread, twist three of them together, and count them as three. A "1,000 thread count" sheet is often a 333-thread-count fabric made of thinner, cheaper yarn than a genuine 300 single-ply percale — and it will feel heavier, sleep hotter and wear out faster. A very high number on a cheap sheet is a warning sign, not a feature.

Weave is the part that matters

Percale and sateen are both usually cotton. The difference is how the threads cross. Percale is a simple one-over-one-under grid: matte, crisp, breathable — the hotel-sheet feel. Sateen floats several threads across the surface before tucking under, which gives it a silky drape and a slight sheen, and traps more heat in the process. Neither is better; they're for different people. If you sleep hot, you want percale, and this is the full comparison.

Fibre decides the temperature ceiling

Linen breathes better than cotton and gets softer with every wash, which is why it costs what it does and why it looks rumpled forever. Cotton is the sensible default. Microfiber is polyester — it's cheap, it's soft on day one, and it is essentially a plastic sheet: it does not breathe, and a hot sleeper will notice within a week. Bamboo viscose sits between cotton and linen, and the "eco" framing on it is mostly noise given how it's processed.

Start here if your bed is too hot

This is the most common reason people end up on a bedding page, and it's worth being blunt about the order of operations. If you're overheating at night, sheets are the cheapest thing to change and they make a real difference — far more than the "cooling" label on a foam mattress ever will. Start with cooling sheets. Then look at your pillow, which sits under the hottest part of you. Only after those two fail is it worth thinking about the mattress itself— and that's us talking you out of the most expensive thing we sell.

Duvet, comforter, or both?

Americans and Britons use these words differently, which is why the listings are a mess. A comforter is a single quilted unit you put on the bed as-is — one piece, no cover, and you wash the whole thing. A duvet insert is a plain white filled shell designed to live inside a removable cover, so you only ever wash the cover. The insert route costs more up front and is dramatically easier to live with. The comforter route is simpler and cheaper until the first spill.

We cover them separately — duvet inserts here and comforters here— because they're genuinely different purchases with different failure modes.

Fill power vs fill weight

These get conflated constantly and they measure different things. Fill power is how much space an ounce of down occupies — it's a measure of quality and loft, so a higher number means more warmth for less weight. Fill weight is simply how much stuff is in there. A high-fill-power, low-fill-weight duvet is light and warm, which is the expensive combination. A cheap duvet reaches the same warmth by stuffing in more low-grade fill, so it ends up heavy and flat.

How we pick

We haven't slept under any of this. We read what the listing actually commits to — fibre, weave, fill power, construction, care instructions — and we apply what those materials genuinely do. Where a claim can't be checked, we say so instead of dressing it up. Our full method is here.
