Quilted Mattress Protector 200GSM 40cm Skirt: what 200GSM actually means

15 June 2026

The Quilted Mattress Protector 200GSM 40cm Skirt is one of the mattress protectors we stock at Daffodil Collections. It sits in our Quilted Protectors range, and this is the short version of what you need to know before you choose a size.

How to choose

There are three kinds and they are not interchangeable. A quilted protector adds a little padding and absorbs the ordinary damp of sleeping. A waterproof one has a membrane and is what you want under a child, a pet or anyone unwell. An encasement zips all the way round and is the only one that addresses dust mites or a mattress you want sealed.

Whichever you choose, the skirt depth has to clear your mattress — and a protector is a consumable: it is cheaper than a mattress and it is meant to be replaced.

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)
Small Double (4ft)120 x 190 cm (4ft 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.

What the numbers mean

200GSM is grams per square metre — the weight of the fabric itself, and the single most useful number on a towel. Below about 400GSM a towel is light and dries quickly; 500 to 600 is the everyday weight most people mean by a good towel; above 600 is the heavy hotel feel that takes longer to dry. At 200GSM, this one sits in the range most households buy.

40cm is the depth of the item itself. On a topper that is the number that decides how much it changes the bed: a few centimetres soften a mattress that is close to right, where a deeper one is what you reach for when the mattress underneath has gone hard.

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.
