Continue shoppingAn extra deep fitted sheet for your box spring gives a neat, snug fit around high mattresses and mattress-plus-topper combos. Your bed stays looking sharp and you sleep comfortably without sheets slipping off. See also Fitted sheet sliding off your box spring? Causes and fixes.
At HappyBed you’ll find extra deep box spring fitted sheets in popular sizes and materials, so you can easily pick the model that fits your bed, like a Box spring fitted sheet 180x200.
When should you choose an extra deep fitted sheet?
Do you have a thick mattress, or want one sheet to cover both mattress and topper? Then an extra deep model is often the right call. The deeper corners and elastic edge help the sheet stay put, which prevents shifting and makes making your bed much easier. Do you have an extra long mattress or box spring? Go for a Box spring fitted sheet 180x220.
How to pick the right size and corner depth
Always measure the width, length and height of the part the sheet needs to cover. For a box spring fitted sheet 180x200 extra deep, it’s not just about the 180x200 size. The right corner depth for a box spring fitted sheet matters too. Using a separate sheet for the topper? Measure only the topper. Want to wrap both layers together? Choose an extra deep model with enough depth.
Pick the material that matches your sleep
Material also affects comfort and fit.
- Cotton is breathable and soft for everyday use.
- Jersey is smooth and stretchy, so it hugs the mattress nicely.
- Flannel feels warmer and is great for colder months.
Always follow the care label to keep your sheet’s fabric and fit in top shape. For extra grip and protection under an extra deep sheet, use a molton fitted sheet (mattress protector).
Frequently asked questions about extra deep box spring fitted sheets
How deep should a fitted sheet for a box spring be?
That depends on the total height of what you want to cover. Measure only the topper, or measure mattress and topper together, and compare that to the stated corner depth.
Can a regular fitted sheet go over a topper?
Sometimes, but it’s more likely to pull tight or pop loose. A topper sheet or extra deep model usually looks neater and stays in place better.
What do you put on a box spring?
A box spring usually includes the base, the mattress and often a topper. On top you use either a fitted sheet for just the topper or an extra deep fitted sheet for both layers together.
Is a box spring fitted sheet 180x200 extra deep suitable for every box spring?
No. Length and width have to match, but the right corner depth is just as important. Always check the height of your mattress and any topper as well.
