30cm Deep Fitted Sheets for a Neater Fit

A mattress that is deeper than average needs a fitted sheet with enough fabric around the sides to stay comfortably in place. Our deep fitted sheets feature a 30cm pocket, giving you additional depth while keeping the bed looking smooth and neatly finished.

The Stoftly range includes plain microfibre fitted sheets in a choice of colours and thread-count specifications, with options for Double, King and Super King beds.

What Is a 30cm Deep Fitted Sheet?

A 30cm deep fitted sheet is designed with approximately 30cm of depth around the mattress.

This extra depth makes it suitable for mattresses that may be too deep for shallower fitted sheets. The elasticated edges wrap underneath the mattress to help hold the sheet in position.

Before ordering, measure your mattress from the top surface to the bottom edge. If you regularly use a mattress topper underneath your fitted sheet, include its depth in your measurement.

Deep Fitted Sheets for UK Bed Sizes

Our 30cm fitted bed sheets are available across several standard UK bed sizes, depending on the individual design.

Double Deep Fitted Sheets

Our Double fitted sheets measure approximately 137 x 193cm with a 30cm depth across the relevant products.

A 30cm deep Double fitted sheet is a practical choice when a conventional fitted sheet does not provide enough coverage around the sides of your mattress.

King Size Deep Fitted Sheets

King fitted sheets in this collection measure approximately 152 x 203cm with a 30cm depth.

They provide the wider proportions required for a UK King mattress while retaining the deeper pocket around the sides.

Super King Deep Fitted Sheets

For larger beds, selected Super King fitted sheets measure approximately 183 x 203cm with a 30cm depth.

Always check the dimensions shown on the individual product page before purchasing, as measurements may vary slightly between designs.

Choose from 200, 400 and 600 Thread Count Options

Our 30cm deep fitted-sheet collection includes several specifications, allowing you to choose the finish that best suits your bedding.

The range currently includes 200 thread count, 400 thread count and 600 thread count fitted sheets, all made from soft microfibre.

Rather than choosing on thread count alone, consider the overall combination of fabric feel, mattress depth, colour and finish when deciding which sheet works best for your bedroom.

Colours for Different Bedroom Styles

A fitted sheet may sit beneath your duvet for much of the day, but the colour can still make a difference when styling your bed.

Choose classic White fitted sheets for a fresh hotel-inspired look, or Grey and Silver Grey for a softer neutral scheme. Selected designs are also available in Charcoal Grey and Soft Pink.

Availability varies by product and size.

Do I Need a Deep Fitted Sheet?

A deeper fitted sheet may be useful if:

  • your existing fitted sheet frequently slips away from the mattress corners;

  • your mattress is deeper than a conventional mattress;

  • you use a mattress topper;

  • your current fitted sheet feels overly tight;

  • you want additional fabric around the sides of the mattress.

The best way to decide is to measure your mattress rather than relying only on the bed-size name.

How to Measure for a Deep Fitted Sheet

First measure the width and length of your mattress to establish whether you need a Double, King or Super King sheet.

Next, measure vertically from the top of the mattress to its bottom edge.

If a mattress topper remains permanently on the bed and sits underneath your fitted sheet, measure the combined height of the mattress and topper.

Compare this measurement with the depth specified on the product page.

If your mattress requires more room than a 30cm sheet provides, explore our 40cm extra deep fitted sheets instead.

Deep Fitted Sheets for Everyday Bedding

Our 30cm fitted sheets are made from soft microfibre and designed for straightforward everyday bedroom use.

The simple plain finishes make them easy to coordinate with duvet covers, pillowcases and other bedding without competing with patterned designs.

Check the individual product page for specific washing instructions, dimensions, colours and available sizes before ordering.

FAQ

What depth is considered a deep fitted sheet?
There is no single universal definition, but a fitted sheet with a deeper pocket provides more fabric around the sides of the mattress than a shallow standard design.

This Stoftly collection specifically contains 30cm deep fitted sheets.
Is a 30cm fitted sheet deep enough?
It depends on the depth of your mattress.

Measure the mattress from top to bottom and include a mattress topper if it sits underneath the fitted sheet. Compare that measurement with the 30cm sheet depth before ordering.
What if my mattress is deeper than 30cm?
If your mattress and topper combination requires more depth, a 40cm extra deep fitted sheet may be more suitable.
Why does my fitted sheet keep slipping off?
A fitted sheet may come away from the corners when its dimensions do not match the mattress correctly or when the pocket is too shallow for the mattress depth.

Checking both the mattress size and depth can help you choose a better fit.
Can I use a deep fitted sheet with a mattress topper?
Yes, provided the combined depth of your mattress and topper is suitable for the fitted sheet.

Measure them together before selecting the sheet depth.
What sizes are available in 30cm deep fitted sheets?
The Stoftly 30cm range includes Double, King and Super King sizes, with availability depending on the individual product.
