Extra Deep Fitted Sheet 30cm Pocket: will 30cm fit your mattress?

1 June 2026

The Extra Deep Fitted Sheet 30cm Pocket is one of the bedsheets we stock at Daffodil Collections. It sits in our Fitted Sheets range, and this is the short version of what you need to know before you choose a size.

How to choose

Three things decide whether a sheet works: the pocket depth, the weave and the fibre. Depth is the one people get wrong — a modern mattress with a topper on it can be 35cm deep, and a 25cm sheet will not stay on it. Weave decides how it feels: percale is crisp and matte, sateen is smooth and faintly glossy, and that is a preference rather than a quality difference. Fibre decides the upkeep — pure cotton is cooler and creases, polycotton creases far less and irons in half the time.

Buy two sets per bed if you can. A bed that has to wait for the wash to finish is a bed that gets made badly.

The sizes it comes in

UK bed names are consistent between retailers; what is not consistent is the mattress underneath them, so measure yours before ordering. These are the sizes this one is made in, with the mattress each is cut for.

SizeThe mattress it fits
Single90 x 190 cm (3ft x 6ft 3in)
Double135 x 190 cm (4ft 6in x 6ft 3in)
King150 x 200 cm (5ft x 6ft 6in)
Super King180 x 200 cm (6ft x 6ft 6in)

If your bed falls between two of these, size up: a fitted sheet that is slightly generous tucks, and one that is slightly tight pulls its corners off in the night.

Colours and pack sizes

There are 6 colourways: Black, White, Ochre, Blush, Charcoal, Grey. Colour is the one decision here that is purely yours — but if this is going into a room that is let or shared, the darker shades hide a coffee ring and the palest ones photograph best.

What the numbers mean

30cm is the pocket depth — the distance the elastic skirt has to travel down the side of the mattress. This is the measurement people get wrong: a standard UK mattress is around 25cm, a pillow-top or a memory foam mattress is often 30cm or more, and a topper adds its own thickness on top of that. Measure yours from the top face to the base, and add the topper.

For hotels, B&Bs and holiday lets

Bedsheets for hotels and B&Bs are washed at a temperature and a frequency no household matches, so the things that matter are the seams, the elastic and how the colour holds. That is why the hospitality trade buys in quantity and in one colour: a matched stock of quality hotel beddings is what makes a linen cupboard workable.

If you are buying for a business, our trade account is where the wholesale beddings pricing lives — the terms are on that page and they are read from the account, not from this article.
