Wool or Cotton Throw: Which Should You Buy?

By Snoozyn · Updated October 2026

Wool and cotton are the two fibres most throws are built on, and they behave quite differently once they are on the sofa. One is the warm, springy fibre that keeps its shape; the other is the light, washable workhorse.

Neither is better in every way. Below we compare them on warmth, weight, washing and looks, then cover the blends that sit in between.

Is a wool or cotton throw better?

A wool or cotton throw is better for different jobs: wool if you want warmth and a throw that keeps its shape with little fuss, cotton if you want something light that can go in the washing machine.

The table below sets the two side by side. It assumes a throw of similar size and weave, because a dense waffle cotton can feel weightier than a fine wool.

	Wool throw	Cotton throw
Warmth	Warm for its weight	Lighter layer
Feel	Springy, lofty, brushed or knitted	Smooth, matte, softens with washing
Creasing	Resists creases	Creases unless crinkled or waffle
Washing	Hand wash in cool water or dry clean	Machine wash 30°C gentle
Drying	Flat, no tumble dryer	Line dry
Our prices	From £90.90 (pure wool)	From £18.90

Which is warmer, wool or cotton?

Wool is warmer. Its crimped fibres trap more air than cotton’s flatter ones, so a wool throw feels warmer than a cotton throw of the same weight and adds a noticeably warm layer on a cold evening.

That does not make cotton thin. Construction matters as much as fibre. A four-layer muslin, a five-layer cotton or a deep waffle weave builds up several layers of cloth with air between them, and a quilted cotton throw adds a padded layer. These feel substantial without the heft of wool. A single-layer woven cotton, by contrast, is a light layer you might use from spring to autumn; our guide to throws for warmer months covers those in detail.

Which is easier to wash and look after?

Cotton is easier to wash. Our cotton and linen throws can go in the washing machine at 30°C on a gentle cycle and be line dried, while wool throws need hand washing in cool water or dry cleaning and must dry flat.

Wool makes up for it by needing washing less often. It sheds dust and odours well, so regular airing and spot cleaning keep it fresh for months. If you are wary of washing wool, our step-by-step guide to washing a wool throw without shrinking it takes the worry out of it. For a throw on a family sofa that will meet spilt tea, muddy paws and crisps, cotton is the more practical choice.

Which looks better on a sofa or bed?

It depends on the look you want: wool reads cosy and wintry, with brushed, knitted or checked surfaces, while cotton reads relaxed and fresh, with flat weaves, stripes, waffle and crumpled muslin.

Wool throws hold a fold well, so they sit neatly over a sofa arm or across the end of a bed and keep their shape. Cotton throws drape more softly and crumple more, which suits an easy, lived-in look. Linen cotton blends add a slubby, slightly irregular texture that looks good in both. If you are weighing linen against cotton more generally, our comparison of linen and cotton bedding explains how the two fibres differ.

Are wool blends or linen cotton a good middle ground?

Yes. A wool blend gives you much of the warmth and texture of wool, usually at a lower price, and a linen cotton blend gives you washability with more texture than plain cotton.

Look at the label: we only call a throw wool-led when wool is at least half the cloth. Our angora wool blend is 55% wool with acrylic and angora, from £84.90, and the ivory herringbone is 70% wool. Blends still need wool care. On the cotton side, the enzyme-washed linen cotton throw is 55% cotton and 45% linen with a soft crumpled finish, at £54.90, and machine washes like cotton. If you want to understand speciality fibres in blends, see how lambswool, merino and standard wool differ.

Which of our wool and cotton throws should you look at?

For a wool throw, start with the oat throw in 100% wool, from £94.90 in three sizes. For cotton, our double-layer cotton gauze throw starts at £18.90.

Between those, the striped combed cotton knit is a 115×160 cm lap throw at £48.90, and the waffle weave cotton is £57.90. The same wool versus cotton choice applies underfoot too; our guide to wool and synthetic rugs covers the floor.

Frequently asked questions

Does a wool throw feel heavier than a cotton one?

Not always. Wool is lofty, so a wool throw can feel full without being heavy. Dense cottons such as deep waffle or five-layer weaves can weigh as much as wool, while a single-layer cotton is lighter than most wool throws.

Will a cotton throw shrink in the wash?

Cotton can shrink slightly, mostly in the first wash and mostly when washed hot or tumble dried. Washing at 30°C on a gentle cycle and line drying, as our care labels advise, keeps any change to a minimum.

Can you use a wool throw in summer?

You can, but most people find a wool throw too warm for summer evenings. A light cotton, linen cotton or muslin throw is the more comfortable choice from late spring to early autumn.

Is a cotton throw warm enough for winter?

A layered cotton throw can be. Four-layer muslin, five-layer cotton, deep waffle and quilted cotton all trap air between layers, so they add a warm layer, though a wool throw of the same weight is warmer.

Do cotton throws pill?

Flat-woven cotton throws rarely pill. Knitted and brushed cottons can form small bobbles where they rub, such as on a sofa arm. A fabric shaver or comb removes them without harming the throw.

Why are wool throws more expensive than cotton?

Wool costs more to produce and process than cotton, and a pure wool throw uses a lot of fibre. For that, it resists creasing, needs washing less often and, cared for properly, lasts for many winters.
