Why you'll love Square Flower
Made of the Rarest Organic Cotton
We scoured the earth for the softest organic cotton we could find: it's the longest staple possible for an incredibly soft hand feel. Less than 1% of the world's cotton meets our quality. This rare fiber produces a smoother, stronger fabric.
Long-Staple Fibres for Strength
Crafted with extra-long cotton fibres that deliver a smoother, stronger weave — designed for lasting softness and resilience through years of washing. The result is a fabric that stays luxuriously soft, even after countless nights of use.
Sateen Weave Finish
Our sateen weave offers a luminous sheen and smooth drape, creating a hotel-quality finish that’s soft, breathable, and indulgent to the touch. It creates a beautifully polished surface that stays cool, soft, and breathable through every season.
Ethically Made, Fairly Paid
Every Square Flower sheet is made by skilled partners who are paid fair wages and work in safe, supportive environments. Our commitment to people is as strong as our commitment to quality — because comfort starts with care.
Ultra-Soft Pre-Washed Feel
Pre-washed for an irresistibly soft texture that only gets better over time — the kind of comfort you look forward to every night. Each wash enhances the fabric’s gentle feel, making it softer with every sleep.
Tailored Fit
Our sheets are made slightly oversized for easy bed making and effortless style, with a refined, wrinkle-minimizing fit that flatters your bed and holds its shape beautifully.

Why Fairtrade Matters
“Fairtrade helps us grow cotton sustainably while providing for our families.”
What is our Raw color?
The Raw color is natural, unbleached cotton with a warm, organic tone that hasn’t been dyed or processed. It offers a unique, earthy aesthetic that pairs with minimalist interiors.
What is long-staple cotton?
Long-staple cotton has longer fibers than regular cotton, creating smoother, stronger, and softer fabric that lasts longer. This makes it more resistant to pilling and ensures lasting quality wash after wash.
How do I properly clean my sheets?
Machine wash cold with mild detergent, tumble dry low, and avoid bleach to protect the fibers and color. With gentle care, your bedding will maintain its softness and strength for years to come.
Do your sheets wrinkle easily?
Our sateen weave resists wrinkles more than percale, but for a crisp look you may lightly iron or steam. Many customers embrace the natural drape for a relaxed, elegant feel.
What is a four-over-one sateen weave?
This weave passes four threads over and one under, creating a silky-soft fabric with a subtle sheen. It balances durability with luxury, giving you both comfort and style.
Do you ship internationally?
Yes. We currently ship to Canada, the United States, and the United Kingdom. Orders typically arrive within 5–10 business days depending on your location.
Customer Reviews
By far the softest sheets I have ever purchased. Deep pockets that allow ease in making your bed. Quality is exceptional and they keep getting softer with every wash. Shipping was FAST. Love that they are Canadian owned
The Customer Service was extremely quick to answer my enquiires & the sheets are great.
Very soft, luxurious feel thick bedsheet. Never been easier to pull over the mattress, would be good even for deep one.
I ordered "raw" and received a very gentle creamy colour sheet, I wish they did dressing gowns because honestly it's so soft you want that on your skin.
Absolutely love the bed sheets. Quality, long staple material and just the right thread count to get the optimum between durability and softness. The sheets also have convenient little tags stitched to the inside telling you which side the long/short one is, respectively.
Fits our super king with mattress protector very comfortably - easy to change bedsheets.
Lovely product! Super soft and fits our matress perfectly even with a matress topper.
I just love this product, I will buy all my bedding from you . I have already recommended Square Flower to several of my friends.
Having just bought a new bed with ethical credentials and a deeper mattress, we needed bigger sheets with matching qualities. Square Flower offered us everything we were looking for in colours and design, and in organic Fairtrade cotton at a very fair price. The order was processed very promptly and the quality of the sheets is as good as we'd hoped. We will definitely order more bed linen from this company.
We had recently bought some big brand fitted sheets but they were not at all comfortable as the mixed fibres seemed clammy. They also didn't work with our wool mattress topper.
The same is not at all true of the smooth comfortable stay in place sheets.
I won't faff about again. I'm going to get more of these.
The fitted bottom sheet that I have purchased is wonderful. Thank you - very satisfied and will definitely be buying more.
sweet dreams are made of this
