This super king fitted sheet measures 180 x 200cm and is made with an extra deep 40cm skirt, elasticated the full way round. It is cut and finished in 200 thread count microfibre to our own specification. A superking fitted sheet has the most surface area of any UK size, which is precisely why the depth and the elastic matter more here than anywhere else.
Super king mattresses tend to be the deepest in the range, and they are the ones most likely to have a topper on them. A deep super king fitted sheet at 40cm fits mattresses up to that depth — a standard 25cm, a thick pocket-sprung or hybrid, or either with a topper added. On a bed this wide, a sheet that is even slightly too shallow will lift off a corner the first time someone turns over.
The elastic runs 360° around the entire skirt. Across 180cm of width that continuous tension is doing real work — corner-only elastic simply cannot hold a sheet of this size flat. The 200 thread count microfibre has enough weight to stay put and smooth out properly, and it holds its shape through repeated washing.
Every super king fitted sheet comes in six colours. White is the timeless hotel choice, crisp and clean against any duvet cover. Light Grey is a soft modern neutral that flatters contemporary bedrooms. Charcoal is a deeper, warmer grey for a cosier, more grounded look. Black is sleek and confident for a high-contrast bedroom. Navy Blue is rich and elegant, adding depth and character. Beige is a calm natural tone that brings warmth and softness.
Posh Tag is a family-run bedding business based on Fieldhouse Industrial Estate in Rochdale, with more than fifteen years in textiles. We manufacture our own pillows and cushion inserts here, filled with pure virgin hollow fibre. Our sheets, including every size in this range, are made to our own specification by mills we have worked with for years, then checked and packed by our team in Rochdale. Because we sell direct rather than through a chain of retailers, there is no extra margin sitting between us and your bed.
Machine washable at 40°C and safe to tumble dry on a low heat. Wash similar colours together, particularly the darker shades — black, charcoal and navy blue — to keep the colour looking rich. Take the sheet out promptly once dry and smooth it flat. Avoid dragging or overstretching the corners when fitting and removing it, and store it clean, dry and folded in a cool, airy cupboard.
The same sheet is made in Single, Small Double, Double and King Size. If you are unsure which you need, the fitted sheet size guide lists every UK bed size in centimetres and inches, and explains how to measure the depth of your mattress.
A UK super king fitted sheet is 180 x 200cm, sometimes listed as 6ft. This one is cut to that size with a 40cm skirt, so it measures considerably larger flat than the mattress.
Yes. Even a deep super king mattress with a topper generally reaches 32cm to 38cm, which the 40cm skirt covers with room to spare.
No. Emperor beds are larger again and this sheet will not fit one. This is cut for a standard UK super king at 180 x 200cm.
Six: White, Black, Navy Blue, Light Grey, Charcoal and Beige.
