Cotton Fitted Sheets

A cotton-polyester blend washes well and resists creasing, which is why hotels use it on heavy turnover. At home, blends trap heat against the body and feel plastic by year two. Pure cotton breathes, softens with washing and sleeps cooler.

The trade-off is a sheet that needs a touch more care. Most home sleepers find the swap worth making within a week.

Marshmellow's fitted sheets are cut with deep pockets to fit modern mattress depths, including most pillow-top and memory-foam mattresses. The elastic is designed to keep the sheet held to the corners through nightly use.

If the mattress is unusually deep, each product page lists the maximum pocket depth before checkout.

Percale is the crisp, matte, breathable option. It snaps cool against the skin and softens with every wash, which makes it the right choice for warm sleepers and summer beds.

Sateen has a quieter sheen and a denser drape, closer to a boutique-hotel hand. It sleeps slightly warmer than percale. Flannel is the third option, brushed cotton for the coldest months.

Wash cool to warm with a normal amount of detergent and no fabric softener. Softener coats the elastic and shortens its working life.

Tumble dry on low rather than high. High dryer heat is the most common cause of elastic failure, ahead of anything else.

Single, double, queen and king, sized for EU, UK and US beds. The three king sizes are noticeably different and a UK king fitted sheet will not fit a US king mattress.

Each product page lists exact dimensions and maximum pocket depth before checkout. If the mattress is between sizes, sizing up sits better than sizing tight.

A well-made cotton fitted sheet, washed properly, lasts five to seven years of nightly use. Failure usually shows at the elastic before it shows at the fabric.

Rotating two sets, one on the bed, one in the cupboard, extends the working life of both by quite a lot.
