Product Information
📝 Product Details
Designed for mattresses that require additional depth, our 600 Thread Count 40cm Extra Deep Fitted Sheet combines a generous fitted pocket with a smooth, simple finish for everyday bedding.
Made from 100% super soft microfibre with a 600 thread count specification, this fitted sheet has a 40cm extra deep pocket and is available in Double, King and Super King sizes. Choose from White or Silver Grey to coordinate easily with your existing bedding.
600 Thread Count Extra Deep Fitted Sheet
This fitted sheet is made from 100% super soft microfibre with a 600 thread count specification. Its smooth plain finish creates a versatile foundation that works easily with patterned duvet covers, neutral bedding and different bedroom styles.
Thread count is one part of the product specification. When choosing a fitted sheet, it is also important to consider the fabric, mattress dimensions and the depth of the fitted pocket.
40cm Deep Fitted Sheet for Deeper Mattresses
The generous 40cm fitted depth, approximately 16 inches, provides additional fabric around the sides for mattresses that need more coverage than a shallower fitted sheet can offer.
Before ordering, measure your mattress vertically from the top sleeping surface to the bottom edge. If a mattress topper stays permanently underneath your fitted sheet, include the topper when measuring the total depth.
This helps you determine whether a 40cm pocket is appropriate for your mattress rather than simply choosing the deepest available sheet.
600 Thread Count Fitted Sheet Sizes
This extra deep fitted sheet is available in Double, King and Super King sizes. Check the width, length and depth of your mattress before selecting your size.
| Bed Size | Sheet Dimensions | Fitted Depth |
|---|---|---|
| Double | 137 x 193cm | 40cm |
| King | 152 x 203cm | 40cm |
| Super King | 183 x 203cm | 40cm |
Extra Deep Double Fitted Sheet
The Double option measures approximately 137 x 193cm with a 40cm fitted depth. It provides UK Double dimensions together with a generous pocket for mattresses requiring additional coverage around the sides.
Measure the mattress depth before ordering, particularly if you use a mattress topper that stays underneath the fitted sheet.
40cm Deep King Size Fitted Sheet
The King option measures approximately 152 x 203cm with a 40cm fitted pocket. This gives you standard UK King dimensions together with the additional depth required by thicker mattresses.
Checking the mattress depth is particularly important when moving from a standard or 30cm sheet to an extra-deep design.
Super King Extra Deep Fitted Sheet
For larger beds, the Super King option measures approximately 183 x 203cm and features the same generous 40cm fitted pocket.
The extra depth provides more fabric around the sides while maintaining the correct width and length for a UK Super King mattress.
White and Silver Grey Fitted Sheets
This design is available in two versatile colours.
White gives the bed a fresh, clean appearance and coordinates easily with colourful, patterned or neutral duvet covers.
Silver Grey creates a softer contemporary look and works particularly well alongside white, charcoal and other neutral bedroom tones.
How to Measure for a 40cm Fitted Sheet
First, confirm the width and length of your mattress so you know whether you need Double, King or Super King.
Then measure vertically from the top sleeping surface of the mattress to the bottom edge. If you use a mattress topper underneath the fitted sheet, measure the combined depth.
This product provides a 40cm / approximately 16-inch fitted pocket.
30cm or 40cm Fitted Sheet?
The main difference is the depth of the fitted pocket.
A 30cm sheet provides approximately 12 inches of depth, while this extra-deep design offers approximately 40cm / 16 inches.
If your mattress does not require the additional depth, one of our 30cm deep fitted sheets may provide a neater fit.

Plain or Striped 600 Thread Count Fitted Sheet?
This product has a smooth plain finish, making it a simple and versatile choice for everyday bedding.
If you prefer a little more texture, you can also explore our 600 Thread Count Striped 40cm Extra Deep Fitted Sheet, which features a subtle satin-stripe design.
