Flat Bed Sheets

Flat bed sheets sold individually — for replacing a worn top sheet, sleeping under one layer in summer, or sizing up a bed for a deeper tuck. Our flat bed sheets are 100% combed long-staple cotton in a 400 thread count percale, with a 4-inch double-turned top hem and top-stitching, available from Twin through Alaskan King.

Why buy flat bed sheets on their own

Buying a whole set to replace one piece is how most linen cupboards end up with four fitted sheets and no matching top sheet. Flat bed sheets are sold here individually for exactly that reason — and for the several other situations where a full set is the wrong purchase.

When you want a flat sheet alone

• Yours has worn through while the fitted sheet is still good
• You use a top sheet under a duvet and go through them faster than anything else
• You want a light layer to sleep under in summer without a duvet at all
• You deliberately size up — using a queen flat on a full bed or a king flat on a queen — to get a deeper tuck. That last one is a genuine trick rather than a compromise, and it is why oversized flat sheets sell.

Specifications

• Fibre: 100% combed long-staple cotton
• Weave: Percale, 400 thread count
• Top hem: 4 in., double-turned and top-stitched (the detail that shows when folded back over a duvet)
• Sold as: Single piece — not a set

Flat bed sheets size guide

The sizing-up trick that works

Using a size larger than your mattress gives you meaningful extra fabric to tuck deep on all four sides — the difference between a top sheet that stays in place through the night and one that untucks by the second time you roll over. A queen flat on a full bed adds roughly 10 in. of tuck; a king flat on a queen adds roughly 16 in. Try it once and you will not go back.

Matching an existing set — a note on dye lots

If you are matching a flat bed sheet to an existing set, note that dye lots shift over time — a white or natural is the safe match; a saturated colour bought two years apart rarely lands identically. For an exact colour match, buy the full replacement set from our bed sheets collection.

How to care for your flat bed sheets

• Machine wash warm with like colours
• Tumble dry low
• Remove promptly and smooth over the bed while faintly damp to reduce ironing
• Skip fabric softener to preserve the crisp percale hand
• A flat bed sheet is the easiest piece in the cupboard to launder and to fold

Frequently asked questions

Can I buy just a flat bed sheet?

Yes — ours are sold individually. That’s the whole point of this listing, so you can replace a worn top sheet without buying a full new set.

What size flat bed sheet fits a queen mattress?

Our queen flat sheet measures 94 × 108 in., which fits a standard 60 × 80 in. queen mattress with a generous tuck. For an even deeper tuck, size up to a king flat.

Do I really need a flat bed sheet?

Culturally divisive question. If you sleep directly under a duvet, no. If you like a light barrier between yourself and the duvet, or you like the tuck-in feel of a top sheet, or you sleep hot and prefer a single light layer in summer — yes.

What’s the difference between a flat bed sheet and a top sheet?

They’re the same thing. “Top sheet” is the American term; “flat sheet” is the neutral one. Both describe the unfitted rectangular sheet that lies over the fitted sheet.
