Upgrade your sleep with our 100% Cotton 200 Thread Count Ultra Deep Fitted Sheet, designed for anyone who wants bedding that stays in place, feels beautifully crisp and solves the nightly struggle of fitted sheets popping off. If your mattress is deep, topped with a protector or finished with a plush topper, this sheet gives you the reliable, snug fit you’ve been longing for.
Woven from single-ply combed cotton yarns, this sheet delivers a true percale experience: cool, lightweight, matte and wonderfully breathable. It’s the ideal fabric for warmer sleepers or those who crave that smooth, fresh “hotel sheet” feel every night. Unlike heavier multi-ply fabrics, this percale weave offers natural airflow and lasting softness that improves with every wash.
Its impressive 46cm (18") depth is what sets it apart, engineered specifically for mattresses up to 38cm (15") deep, ensuring no pulling, slipping or corner lift. Fully elasticated around all sides, it wraps neatly and securely for a crease-free finish.
If you’ve ever felt frustrated by fitted sheets that won’t stay put, or bedding that leaves you too warm at night, this is your solution: breathable comfort, exceptional durability and a fit you can trust.
Asked by: Anonymous
The fitted sheet has a 46cm depth, but we recommend it for mattresses up to around 38cm deep so there is enough extra fabric to tuck neatly underneath the mattress and help keep the sheet secure.
This extra allowance is especially useful if you have a mattress protector or topper, as it helps prevent the sheet from slipping off during the night.
As your mattress is 43cm deep, you would still have around 3cm of extra material, so it may fit, but it will depend on the exact shape and firmness of your mattress.
We do offer free returns, so you are welcome to try it on the bed. If it is not quite right, you can return it to us, as long as it has not been washed or used.
Answered by Belledorm Sleep Experts
Thank you for getting in touch, and apologies for any confusion caused.
In our 100% Cotton 200 Thread Count Ultra Deep (46cm) range, we unfortunately don't offer a 90 x 200cm (long single) size, the single fitted sheet in this quality is made to 90 x 190cm.
However, if you're able to consider our Jersey Cotton fitted sheets, these are designed with natural stretch, which means the single size comfortably fits both 190cm and 200cm length mattresses. It's a really practical option if you need that bit of extra length without having to size up.
The sheets are widely appreciated for their excellent fit on deep mattresses, with many noting the 46cm depth as ideal for a secure, comfortable fit without slipping. Customers frequently mention the soft, fine cotton material, which washes and irons well, maintaining its quality over time. The colour accuracy and overall feel of the fabric receive positive remarks, contributing to a pleasant sleeping experience. Some users highlight practical details like labels indicating head and toe, which simplify making the bed. While the sheets are generally praised for their quality and comfort, a few mention that the fabric feels slightly thin, though this has not detracted significantly from satisfaction. Overall, the product is regarded as reliable and well-suited to those needing extra-deep fitted sheets.
Lovely silky material, great colour
This is the second one (46cm deep) and it fits perfectly
Brilliant so good I now have 2
Great Matt cotton sheets with an extra deep sheet perfect for our mattress
Comfortable, nice quality, good deep size fitted sheet.
Nice and deep sheet, feels good quality.
Lovely Matt crops feel, just a little thin maybe but we will see. Purchased a few more as well
Absolutely brilliant, the 46cm means the sheet fits perfectly with plenty to tuck under. The quality of the product is excellent for the price, I bought 2 and was so pleased I ordered another 2. Delivery was prompt with no issues, I have told friends and family about the product and service
Lovely cotton, washed and ironed well but the best thing of all..... no more fighting to get the bottom sheet onto mattress. Was an absolute game changer. Ordered another within days.
Very pleased with 46cm deep sheet and matching pillow case's All opened washed dried and on bed. Sheet fitted perfectly also at a great price!! Thanks.
Great deep sides fitted perfectly on my new mattress without slipping off
Excellent service. Good quality bedding. Needed extra deep fitted sheets and Belledorm provided just what we needed.
Great sheets and extra deep so fit the mattress comfortably. Added bonus of a label indicating head/toe which saves the attempt to put it on the wrong way round. Lovely quality and they wash up really well.
Good depth and fine cotton. Fits mattress well.
Perfect. Will be purchasing further items . Size perfect and colour just what was required
This is good.
Very soft and comfortable and fits really well on my deep mattress. Excellent product and I will definitely buy it again.
Excellent, that's why this is the 3rd one l have purchased!
An excellent buy and fits perfectly
Excellent quality, great price, free and fast delivery
More than happy with the professionalism and service provided by Belledorm. The king size extra deep sheet is better than I hoped and is of very good quality. I also bought 400tc Oxford pillowcases on the same order and these are of a softer and tighter weave. I have no hesitation in recommending both these items
The sheet is a good size and I struggled to find one elsewhere that fit my deep mattress with foam topper. However the sheet is incredibly thin and I found it to be quite scratchy. I had to get out of bed and put some leggings on so that the sheet wasn't touching my skin because it was making them itch. I didn't expect it to be amazing for the price but I've had cheap sheets before and not had this problem with anything that is 100% cotton. I will give it another wash and see if it improves and if not I won't bother using it again.
Often use Belledorm and always happy with goods.
As usual fabulous quality products, exceptional quality and great prices, very quick delivery, I highly recommend this company for all your bedding, thank you from a happy customer
