Perfect-Fit Flat & Fitted Cotton Sheets

Q: Will flat sheets shrink after washing?

They’re lab-tested to resist shrinking and fading, so your sheet stays true to fit and color through hundreds of washes. They are durable and last 3 to 5 years.

Q: Can you use a flat sheet by itself (no top cover) in warm weather?

Yes - it’s one of the best ways to sleep cool. A cotton percale flat sheet alone offers just enough coverage for comfort without trapping heat, making it a favorite for summer nights or naturally warm sleepers.

Q: How deep should the pocket be for my mattress?

Our fitted sheets sized full, queen, and king have a true 16" pocket, designed to fit mattresses from 8" to 16" deep. Twin-Twin-XL sizes fit up to 15” deep. The 360° all-around elastic ensures a secure, no-shift fit.

Q: Will fitted sheets loosen or pucker after washing?

No. They’re cut generously and designed to fit well after washing. The all-around elastic edge is durable and prevents slipping, while the natural cotton weave relaxes slightly after the first wash for a smoother, tailored fit.

Q: Can these fitted sheets work on adjustable or split beds?

Yes - our fitted sheets are flexible enough for adjustable bases, moving cleanly with the mattress. For split beds, we recommend ordering individual Twin XL fitted sheets for each side to maintain fit during adjustments. We also offer split-king sizes in many of our collections.

Q: How tight should the fit be - when is it too tight or too loose?

A good fit sits snug without strain. If corners pop off, it’s too small; if fabric pools or wrinkles, it’s too large. When fitted right, the sheet should glide smoothly over the mattress and stay put through the night.

Discover our breathable cotton sheets. Fitted sheets feature deep pockets and strong elastic for a perfect fit, while flat sheets add the ideal top layer for effortless comfort.

Is a flat sheet necessary when using a duvet cover?

It’s a matter of preference. Many skip the flat sheet when using a duvet cover for a minimalist setup, while others like the extra layer for easy washing and temperature control.
Ours are soft and breathable enough to work beautifully either way - comfort without the clutter.

Which weave or thread count is best for flat sheets?

That’s on you as each offers a different hand-feel, while all being naturally breathable and comfortable. We offer Flat Sheets in the following:

Everyday Ease 400 TC Sateen: lightweight, silky, and easy to care for; perfect for everyday use.
Weekend Soft 500 TC Sateen: slightly denser than 400 TC with a smoother handfeel and soft-silky glides.
Restful Retreat 600 TC Sateen: Balanced midweight with luminous sheen with silky-smooth hand feel.
Natural Touch Organic Percale - lightweight, crisp, matte finish and cool-to-the-touch for warm climates or a hotel-style feel.

Will flat sheets shrink after washing?

They’re lab-tested to resist shrinking and fading, so your sheet stays true to fit and color through hundreds of washes. They are durable and last 3 to 5 years.

Can you use a flat sheet by itself (no top cover) in warm weather?

Yes - it’s one of the best ways to sleep cool. A cotton percale flat sheet alone offers just enough coverage for comfort without trapping heat, making it a favorite for summer nights or naturally warm sleepers.

How deep should the pocket be for my mattress?

Our fitted sheets sized full, queen, and king have a true 16" pocket, designed to fit mattresses from 8" to 16" deep. Twin-Twin-XL sizes fit up to 15” deep. The 360° all-around elastic ensures a secure, no-shift fit.

No. They’re cut generously and designed to fit well after washing. The all-around elastic edge is durable and prevents slipping, while the natural cotton weave relaxes slightly after the first wash for a smoother, tailored fit.

Yes - our fitted sheets are flexible enough for adjustable bases, moving cleanly with the mattress.
For split beds, we recommend ordering individual Twin XL fitted sheets for each side to maintain fit during adjustments. We also offer split-king sizes in many of our collections.

How tight should the fit be - when is it too tight or too loose?

A good fit sits snug without strain. If corners pop off, it’s too small; if fabric pools or wrinkles, it’s too large. When fitted right, the sheet should glide smoothly over the mattress and stay put through the night.

How do I fold a fitted sheet?

Hold it by the corners lengthwise, tuck each corner into the next, then lay it flat, smoothing edges before folding into thirds.
