How To Wash Egyptian Cotton Bedding

  • Wash at 30°C ( 86°F) with a minimal amount of gentle detergent
  • Don’t add any additional products
  • Use a gentle wash cycle
  • Air-dry where possible
  • Iron on a low heat. You can put a cloth on bedding set when ironing

How To Dry Egyptian Cotton Bedding

With Egyptian Cotton bedding we would always recommend that you air dry the fabric on a clothesline. Hung correctly, the creasing will be minimal and you won’t have to spend as long on the ironing. Air drying also to maintain the cotton’s lovely natural scent.

If you must tumble dry your Egyptian Cotton bedding, make sure that you use a relatively low heat. Remove the sheets from the dryer as soon as possible after the cycle has finished and fold them. This will help prevent any stubborn creases from setting in.

Iron the sheets whilst they are still slightly damp with the iron set to a low heat. 

Egyptian Cotton bedding is a high-quality item with a truly luxurious feel. Treated well, that stunning quality will last for years to come.

How To Wash Silk Bedding

The safest way to wash delicate silk bedlinen at home is to hand wash them.

  • Fill a basin with cool water
  • Add a few drops of detergent for delicates
  • Soak the sheets
  • Agitate the item in the water
  • Rinse in cold water
  • Absorb excess water with a towel
  • Hang the sheets to dry
  • Iron on a low heat if necessary

Frequently Asked Questions

Egyptian Cotton has an unmistakably luxurious feel because of its long-staple fibres, producing a softer and longer-lasting fabric. Along with softness and durability, it is also known for its beautiful lustre and absorbent capabilities, making it perfect for producing luxury bedding.
They feel incredibly soft and comfortable; creating a luxury hotel feel right at home. Egyptian Cotton is also strong and long-lasting, so your sheets will stand the test of time and continue to get better with age. Lastly, Egyptian Cotton allows air to pass through and is super breathable, meaning it is a great option for year-round use.
Put simply, the thread count refers to the amount of warp and weft (threads going down and across) within a single square inch. So, with a 500 Thread Count, there are 500 overlapping threads within one square inch. The higher the number, the more threads per square inch and the denser the fabric.
500 Thread Count creates bedding that feels luxuriously soft and is super easy to wash and care for. This is because the fabric is very flexible. However, at the other end of the spectrum, 1000 Thread Count bedding guarantees quality over many years, yet this is a thicker fabric, perfect if you want that hotel bedding experience.
Egyptian Cotton sheets will be with you for the long-haul. If you are looking for bedding that is durable and will retain its quality over time, Egyptian Cotton is well and truly worth the investment. On top of this, its soft feel will add a touch of luxury and relaxation to your day to day, so why not treat yourself?

This fluffed right up out of the package. It is lightweight but full enough to be comfy and warm. The fabric is soft and luxurious to the touch. Hopefully it will hold in the down filling over time.

Nice, soft, fluffy ☁️💛

Tiffany Gray

I knew I wanted to spend a little more than usual and get a quality comforter, and boy did this one deliver! The comforter is so fluffy and soft - it settles around you like a cloud when you climb into bed.

Jery Y

Other stores would sell 750-800 fill power at >$1,000 but with less $500 I got this high quality comforter that makes me want to lay in bed all day long. You will not regret getting this comforter, this is a must-have item during winter time!

Love it

I could not be happier with this purchase! The winter seems to get colder each year and I hate turning on heater since it gives me nosebleed and makes my skin dry so I was looking everywhere for a down comforter that would offer highest level of warmth but lightweight at an affordable cost. I'm ecstatic I found exactly what needed!
