The Complete Guide
Fitted Bed Sheets
The sheet that touches your skin all night. How to choose the right one — from pocket depth to elastic quality to the feel of the cotton itself.
What to Look For
What Makes a Great Fitted Sheet?
A fitted sheet has three jobs: stay on the mattress, feel good against your skin, and last through hundreds of washes. Most sheets fail at the first one. Here's what separates a fitted sheet that works from one that ends up balled at the foot of the bed by 3 AM.
360° Elastic
Elastic should run the entire perimeter — not just the corners. Full-perimeter elastic is the difference between a sheet that stays and one that pops off.
Correct Pocket Depth
Too shallow and it won't fit. Too deep and it bunches. Match the pocket depth to your mattress height — with an inch or two of tolerance.
Quality Cotton
The weave and cotton quality determine how the sheet feels, how it breathes, and how it holds up over time. Natural cotton gets softer with every wash — synthetics don't.
The #1 Buying Question
Deep Pocket Sizing — Will It Fit My Mattress?
This is the question behind most fitted sheet returns: “it didn't fit.” The issue is almost always a mismatch between mattress depth and pocket depth. Here's how to get it right.
How to Measure Your Mattress
Remove all bedding. Stand a tape measure at the edge of the mattress, from the bottom of the mattress where it meets the bed frame or foundation to the top sleeping surface. Include any pillow top or mattress topper if you plan to sheet over it.

Materials Matter
Cotton vs. Synthetic Fitted Sheets
Your fitted sheet is the layer closest to your body for 6–8 hours a night. What it's made of matters more than most people realize.
100% Cotton
- Natural plant fiber — no plastic content
- Gets softer with every wash
- Naturally breathable — moves moisture away
- No microplastic shedding in the wash
- Durable across hundreds of wash cycles
- Biodegradable at end of life
Microfiber / Polyester
- Petroleum-derived synthetic fabric
- May pill or feel rough after repeated washing
- Can trap body heat against the skin
- Sheds microplastics into waterways every wash
- Lower initial cost, shorter useful life
- Non-biodegradable
CDD has never made a synthetic sheet. Every fitted sheet we sell is 100% natural cotton — sourced responsibly, woven in our own facility, and tested by the Good Housekeeping Institute.
Choose Your Feel
Thread Count — Find the Right Fitted Sheet for You
Thread count describes the weight and feel of the fabric. It's a selection tool, not a ranking. Lower thread count means lighter and more breathable. Higher means denser, smoother, and more weight against the skin. Neither is “better” — it depends on how you sleep.

Make Them Last
Fitted Sheet Care
Cotton fitted sheets are easy to care for — and they get softer with each wash. A few simple habits will keep them looking and feeling new for years.
Machine wash in warm or cold water. Tumble dry on low. Remove promptly to minimize wrinkles. Avoid bleach — it weakens cotton fibers over time. If you use a dryer sheet, use a fragrance-free one, or skip it entirely (cotton doesn't need it).
The most common cause of premature wear isn't washing — it's friction. Rough or jagged mattress surfaces, exposed springs, or abrasive mattress protectors can wear through fabric faster. A smooth mattress surface extends sheet life significantly.
Fitted Bed Sheets: How to Find the Fit That Actually Stays
Fitted bed sheets have one real job: stay on the mattress through a full night's sleep. The best fitted sheets that stay tight combine two things - a pocket deep enough for your mattress and elastic that runs the full perimeter, not just the corners. So what does a fitted sheet look like when it's actually built to last? Look for even elastic stitched around all four sides, a pocket depth listed in inches, and a weave that feels smooth rather than papery.
Common Questions
Fitted Sheet FAQ
What is a bed fitted sheet?
A fitted sheet is the bottom sheet with elastic edges that wrap the mattress. Fitted bed sheets use 360° elastic and a pocket sized to your mattress depth to stay put.
What is the difference between fitted bed sheets and normal bed sheets?
Fitted sheets have elastic edges that grip the mattress; flat sheets are loose and just tucked in. Fitted bed sheets stay put all night, while flat sheets can shift.
How to choose a fitted bed sheet?
Match pocket depth to your mattress height, check for full-perimeter elastic, and pick a cotton feel you like - that's how you land the best fitted sheets that stay tight.
Do you really need a fitted sheet?
Yes. A fitted sheet keeps the mattress covered and prevents bunching. Without one, sheets slide loose - fitted bed sheets are built to solve exactly that.
How often should you wash sheets?
Wash fitted sheets weekly with regular use. Natural cotton fitted bed sheets get softer with every wash and hold up well over years of laundering.
