Extra Deep Double Fitted Sheets: How to Choose the Perfect Fit for Your Bed

There’s nothing more annoying than waking up to a fitted sheet that has slipped off the corners of your mattress overnight. If you have a thicker mattress, use a mattress topper or simply want a smoother and more secure fit, standard sheets just don’t cut it.

That’s why more UK households are switching to extra deep double fitted sheets.

Designed to fit deeper mattresses comfortably, these fitted sheets give better coverage, more comfort and a cleaner looking bed. Whether you have a memory foam topper, a pillow top mattress or a luxury deep mattress, choosing the right fitted sheet can make all the difference to your bed.

In this guide you’ll learn how to choose the best extra deep double fitted sheets, what depth you actually need, which materials work best and how to avoid common buying mistakes. We’ll also cover practical tips for looking after your sheets and setting up your bed for better sleep.

Why Extra Deep Double Fitted Sheets Matter

Many people don’t realise that mattress depth has increased significantly in recent years. Mattresses are often much thicker due to:

• Memory foam layers
• Pillow top designs
• Mattress toppers
• Hybrid mattress construction
• Added comfort padding

As a result regular fitted sheets don’t stay on.

Extra deep fitted sheets are designed for thicker mattresses, so you get a snug fit without corners popping off during the night.

A properly fitted sheet can:

• Improve sleep comfort
• Keep your bed looking tidy
• Reduce bunching and wrinkles
• Protect your mattress more effectively
• Make changing bedding easier

For UK sleepers with mattress toppers or luxury mattresses this small upgrade can make a big difference.

What Are Extra Deep Double Fitted Sheets?

Extra deep double fitted sheets are fitted sheets with deeper pockets to fit taller mattresses.

A standard UK double mattress measures approximately:

• 135 cm x 190 cm

But mattress depth can vary.

Standard fitted sheets fit mattresses around 25 cm deep, extra deep fitted sheets fit mattresses from 30 cm to 40 cm or more.

If your fitted sheet keeps slipping off or feels too tight around the corners you may need deep fitted sheets double size rather than standard bedding.

How to Measure Your Mattress Correctly

Before buying a deep fitted sheet measure your mattress properly.

Step 1: Measure Width and Length

For most UK double beds:

• Width: 135 cm
• Length: 190 cm

Step 2: Measure Mattress Depth

Use a tape measure from the base to the highest point of your mattress, including any topper.

This is especially important if you use:

• Memory foam toppers
• Pillow top mattresses
• Quilted mattress protectors

If your mattress depth exceeds 30 cm, extra deep double fitted sheets are usually the best choice.

Who Benefits Most From Extra Deep Fitted Sheets?

Extra deep fitted sheets are useful for more people than you might think.

People Using Mattress Toppers

Mattress toppers add comfort but also increase mattress height. A standard fitted sheet may no longer fit securely.

An extra deep fitted sheet helps keep everything in place while maintaining a smooth sleep surface.

Hot Sleepers

Loose sheets can bunch up and trap heat. A properly fitted sheet allows better airflow and improves overall sleep comfort.

Families With Children

Children often move around during sleep, pulling sheets loose. Deep fitted sheets double size options stay fitted more securely throughout the night.

Luxury Mattress Owners

Premium mattresses are often thicker than traditional models. Investing in extra deep fitted sheets protects both comfort and appearance.

Guest Bedrooms

Guest beds with toppers or upgraded mattresses benefit from fitted sheets that stay neat and wrinkle free.

Choosing the Best Material for Extra Deep Double Fitted Sheets

Material affects softness, breathability, durability and maintenance.

Cotton

Cotton is still one of the most popular choices in the UK because it is:

• Breathable
• Soft
• Durable
• Easy to wash

Egyptian cotton and brushed cotton are especially popular for comfort and luxury.

Microfibre

Microfibre sheets are affordable and wrinkle resistant. They are ideal for busy households and guest bedrooms.

Bamboo Blend

Bamboo fabrics are growing in popularity because of their:

• Moisture wicking properties

Jersey Knit

Jersey fitted sheets feel soft and stretchy, similar to a comfortable t-shirt.

They work particularly well as extra deep fitted sheets because they flex around thicker mattresses more easily.

Why Fit Matters More Than You Think

Poorly fitted bedding affects both comfort and sleep quality.

If your sheet constantly slips:

• You may wake during the night
• Fabric can bunch under your body
• The mattress may become exposed
• Your bed can look untidy

A properly fitted double bed fitted sheet deep enough for your mattress stays secure and smooth throughout the night.

This is especially important for couples, active sleepers and children.
