Frequently Asked Questions

Is 40cm a deep fitted sheet?

Yes, a 40cm fitted sheet is considered a deep fitted sheet. It is designed for thicker mattresses, including pillow-top and layered beds. A standard mattress usually needs less depth, so 40cm gives extra coverage. It helps the sheet stay in place all night. This depth is popular in UK and modern homes.

What depth are extra deep fitted sheets?

Extra deep fitted sheets usually start from 40cm to 46cm They are made for very thick mattresses, mattress toppers, or adjustable beds. If your bed has multiple layers, extra deep sheets are a better choice. They offer a snug and secure fit without slipping.

Do deep fitted sheets shrink after washing?

Good-quality deep fitted sheets shrink very little if washed properly. Cotton sheets may shrink slightly after the first wash. Washing in cold or warm water helps prevent this. Always follow the care label to keep the size and fit perfect.

Are deep fitted sheets worth buying?

Yes, deep fitted sheets are worth it if you have a thick mattress. They fit better, look neater, and don’t come off easily. You won’t need to keep adjusting them. They also last longer because they are not overstretched.

How do I measure my mattress for a fitted sheet?

Measure the length, width, and depth of your mattress. Depth is the height from the base to the top, including any topper. Use a measuring tape for accuracy. Choose a fitted sheet with a depth slightly more than your mattress size.
