Premium Portuguese Cotton Flannel Sheet Set

Each set includes everything you need for a complete bed refresh - one flat sheet, one fitted sheet, and two pillowcases. The fitted sheet has deep 18" pockets for full, queen and king sizes only, whereas the Twin sheet set comes with deep 16” pockets and a strong all-around elastic that stays put, even on thick mattresses or toppers. Top/Bottom tags simplify bed making.

Start with your mattress size - Twin, Full, Queen or King - then check the depth. As mattress sizes are standard in the US, our sheets are designed to fit them correctly. For mattress depth, each of our products has the “fits up to” mentioned clearly. Most of our Twin sizes fit mattresses up to 16” deep while the full, queen, king fit up to 18" deep. The elastic hugs snugly without slipping, so even slimmer mattresses stay smooth.

Better is very subjective, however, high thread count is more durable and luxurious than a low thread count. Different thread counts mean different types of threads and density, resulting in different weight and feel of fabric. We have mentioned the hand feel of each of our thread counts for you to make an informed decision.

If you sleep warm, percale is your match. It’s airy, matte, and naturally cool to the touch. If you prefer a silky glide and a slightly cozier feel, sateen is right for comfort. Both being cotton, they are naturally breathable thus cool - so it simply depends on how you like to sleep.

We design for real life. Our sheets are lab-tested to resist shrinking and tearing. A small natural tightening may happen after the first wash, but it’s already built into the sizing.
For best results: machine wash warm, tumble dry low, and remove promptly. No special care needed.

Once a week keeps them fresh and comfortable. If you’re a hot sleeper or have allergies, every 7-10 days works best. The fabric is made to soften with every wash, holding up beautifully over time.

With simple care, our cotton sheets can last 3 to 5 years or more. They’re built with durable stitching, colorfast dyes, and strong fabric that keeps its smoothness through hundreds of washes - comfort that lasts as long as the habit.

Yes. For many of our products you can purchase fitted sheets, flat sheets, or pillowcase pairs separately - all made with the same cotton, weave, and color options as the main sheet sets. Perfect for refreshes or mixing and matching.

Every California Design Den sheet is OEKO-TEX® Standard 100 certified, meaning it’s been tested for hundreds of harmful substances and is safe even for sensitive skin. Our Organic Cotton Percale is a GOTS Certified product.
