Investing in quality bedding means caring for it well. Our Amstelinen Organic Cotton bedding is crafted from 100% organic cotton with a smooth 300 thread count sateen weave—chosen for its softness, breathability, durability, and beautifully refined finish. With the right care, your bedding will continue to feel soft, comfortable, and inviting wash after wash.
Washing with Care
For everyday care, we recommend washing your organic cotton bedding at 40°C on a gentle or normal cycle, using a mild liquid detergent. Wash with similar colours and, where possible, turn duvet covers and pillowcases inside out before washing to help protect the fabric’s smooth sateen finish.
For white bedding, a non-chlorine bleach or gentle oxygen-based brightener may be used occasionally if needed. For coloured bedding, avoid chlorine bleach and harsh detergents, as these can gradually affect the colour and finish of the fabric.
Avoid overloading the washing machine. Giving your bedding enough room to move allows it to rinse thoroughly and helps reduce excessive creasing.
Drying & Ironing
Whenever possible, line drying is the gentlest option and helps preserve the fabric while reducing energy use.
If you prefer to tumble dry, use a low to medium heat setting and remove your bedding promptly once the cycle has finished. Over-drying at high temperatures can cause unnecessary shrinkage and may weaken natural cotton fibers over time.
If you prefer a crisp, freshly pressed finish, iron on a warm to medium-hot setting while the fabric is still slightly damp.
Minimising Wrinkles
Natural cotton will crease, especially after washing—and this is completely normal.
To minimise wrinkles, shake out your bedding before drying, avoid overcrowding the dryer, and remove it promptly once dry. Smoothing and folding the bedding while it is still slightly warm can also help create a neater finish.
Softer with Every Wash
One of the beautiful characteristics of quality cotton is that it naturally becomes softer with regular washing and use.
We recommend avoiding excessive fabric softener. While it can create an immediate soft feel, repeated use may leave a coating on the cotton fibers and reduce their natural breathability and absorbency.
Natural Fit & Fabric Changes
As with most natural cotton products, a small amount of shrinkage may occur, particularly during the first few washes. Following the recommended washing and drying temperatures will help minimise this.
The subtle lustre of the sateen weave may also become softer and more relaxed over time. This is a natural characteristic of cotton and does not affect the quality, comfort, or performance of your bedding.
For the Perfect Duvet Fit
To keep your duvet insert securely in place, use the interior corner ties inside your Amstelinen duvet cover. They help prevent the duvet from shifting or bunching during the night and keep your bed looking beautifully even.
For easier bed making, look for the long-side and short-side indicators thoughtfully added to selected Amstelinen bedding.
Always follow the sewn-in care label.
