Deep Fitted Sheets for Thicker Mattresses

If you have a thicker mattress or use a mattress topper, a deep fitted sheet can provide the additional depth needed for a secure fit. Choosing the correct sheet depth helps prevent the corners from lifting or the sheet coming loose during the night.

Before buying, measure the full height of your mattress and include the depth of any topper you intend to use. This makes it easier to choose a fitted sheet with enough fabric to sit securely around the mattress.

Fitted Bed Sheets – Frequently Asked Questions

What is a fitted bed sheet?

A fitted bed sheet is designed with elasticated corners that wrap around your mattress, helping the sheet remain securely in position. Unlike a flat sheet, a fitted sheet is shaped to fit directly over the mattress.

How do I know what size fitted sheet I need?

Choose a fitted sheet that matches your mattress size, such as Single, Double, King Size or Super King. You should also check the mattress depth, especially if you use a mattress topper, as this increases the overall height of the mattress.

What does a deep fitted sheet mean?

A deep fitted sheet has additional fabric depth to accommodate thicker mattresses. They are also useful for beds with a mattress topper where standard-depth sheets may not provide enough material to fit securely.

What material is best for fitted bed sheets?

The best material depends on your personal preference. Cotton fitted sheets are popular for their natural feel and breathability, while polycotton offers a practical combination of cotton and polyester with easy-care properties.

How often should you wash fitted bed sheets?

Many people choose to wash their fitted sheets approximately once a week to maintain good bedding hygiene. Always follow the individual manufacturer's care instructions for the correct washing and drying method.

Why does my fitted sheet keep coming off the mattress?

A fitted sheet can come loose if it is the wrong size, does not have sufficient depth or has been fitted incorrectly. This can be particularly noticeable with thicker mattresses and mattress toppers. Measuring the mattress depth and choosing a suitable fitted sheet can help provide a more secure fit.

Can I use a fitted sheet with a mattress topper?

Yes. Measure the combined height of your mattress and topper before choosing a fitted sheet. A deep fitted sheet may be required to provide enough depth to fit securely over both.
