How should I care for your products?

See our care guide.

What's your Raw color?

Pure and very, very soft, undyed cotton. You will see specs of natural material like tiny bits of seed, left over from the production process.

Is your packaging eco-friendly?

Our gift boxes are made to be re-usable and are manufactured with recycled card. We use varnish, not laminate (laminating covers the board in polypropylene which is hard to recycle). They are produced in a SA8000 certified factory to ensure fair treatment of workers. Our beautiful fabric pouches the sheets arrive in are made from cut-offs at the factory to ensure nothing is wasted.

What are the benefits of organic cotton?

Do your sheets wrinkle?

Our sateen weave creases less than other types of weave, but some creasing is natural. Since our cotton is organic, we don’t add harsh anti-wrinkle chemicals.

If you use a dryer we recommend taking the sheets out 5 mins before the end of the cycle and hanging or laying out them flat for best results.

Amazing

I am absolutely delighted with my order, this set look great and feel extra soft and fresh. I loved all the colour too and the delivery was very quick. The packaging is very beautiful. And it's organic! Simply perfect! I am getting more in other colours now, thank you, guys!

Ordering More!

I can’t wait to order another set! They feel great on the skin. It’s hard to find Super King pillow cases in an organic fabric. Very pleased with these.

Silky heaven

Beautiful from the 1st use and getting softer each time they are washed. Definitely recommend these covers.

Great products

Great service, quick delivery and beautifully packaged! I really love the quality of these sateen sheets and bed sets! I would definitely recommend and will use the products in the future!

Beautiful bedding

After purchasing the navy duvet set I ordered the fitted sheet in white . The quality is second to none , the best bedding I have ever bought . Each item comes in its own drawstring bag so no plastic waste . I would recommend 100%.

★★★★★

Luxurious

This is without any doubt the best bedding ever. The “feel” of the cotton is better than anything I’ve ever encountered. The fit of the fitted sheets is spot on, and so is the duvet. I also like the taped edges on the fitted sheets - not just a cheap seam!

Mr Andrew Walley

★★★★★

Wonderful quality

The colour and the quality of your product are both spot on. WONDERFUL. Also your customer service: next day delivery- FANTASTIC! Altogether a very efficient, enjoyable quality shopping service- the packaging is a treat! I'll be buying more........

Quality sleep guaranteed

I was concerned about spending a fair amount on some bedding, but I will never question it again. Washes beautifully, feels amazing and just such a good night’s sleep! The packaging was also a big plus for me - no unnecessary plastics and a beautiful box which can be recycled (or even reused at home).

Haven't had a chance to use the top sheet & pillow cases yet but if they are anything like the presentation I'm going to be in for another treat.

Amazing

We were in need of new bedding so we bought the duvet cover set as well as the sheet set and we amazed at the quality! So happy we took a chance and purchased our bedding from Square Flower. We will be ordering from this company from now on.

Very pleased!

I searched for all organic bedding for a while before finding Square Flower. I do a lot of research before buying almost anything so I based a lot of my decision for the sheets set on reviews. I can happily say the reviews have been right so far. Very nice quality & they wash well with no shrinking. Not quite as soft as I hoped just yet but I am sure they will get softer with more washings as the reviews say. I will definitely buy from this company again!

A must for us!

I love this flat sheet as it’s soft and cozy between the fitted sheet and our duvet cover. My next purchase will be a duvet (after saving up). Flat sheet isn’t necessary for all because the fitted sheet is so awesome but why not have more awesome! ;)

To top sheet or not to top sheet?

I loved my Organic (raw) Duvet cover so much, I immediately ordered the Organic (raw) sheets and a top sheet. My husband doesn't care for a top sheet but I do! So guess what? Yesssss, I ordered the top sheet too because these sheets are too lovely not too have the full set (Sheets, pillow cases AND top sheet!!).
