A new rug almost always arrives rolled up or folded – and that is exactly why it is anything but flat when you first unroll it. Waves, curled-up corners, creases from the packaging: completely normal, but still annoying when you want your room finished right away. The good news: flattening a rug is usually no rocket science, it simply comes down to the right method and a little patience. Depending on the material and how tightly the rug was packed, it takes anywhere from a few hours to two weeks for it to lie flat on its own. With a few targeted tricks, though, it goes much faster.

Why new rugs get waves and creases
For your rug to reach your home at all, it has to be transported – and the most space-saving way to do that is rolled or folded. This is the reason for most waves: over days or weeks, the fibres have "got used to" one rolling direction and now need time to stretch out again. With some deliveries, a rug even arrives slightly creased because it was folded too tightly when it was packed. This usually sorts itself out on its own, too.
But there is a second, often overlooked cause: furniture. If a table or sofa stands in the same spot for a long time and is then moved, the rug underneath can start to shift or ripple because the pile direction was put under uneven strain by pressure and movement. That is a different problem from the classic transport crease – by the way, if you are looking for help with dents from furniture legs, that is a topic of its own that we cover separately.
How long a rug needs to lie completely flat depends mainly on the material. Thin, flat-woven rugs often settle within a few days, while thicker models or those woven from natural fibres can take up to two weeks. With the following methods, you can speed up the process noticeably.
The gentlest methods for flattening
Before you reach for heat or chemicals, it is always worth trying the gentle way first. The following five methods can be combined however you like and are suitable for almost any rug, such as 'Loop' or 'Nomad'.
1. Roll it up the other way
The most effective fix for a rolled rug that simply refuses to lie flat is rolling it up the other way. Simply roll the rug in the opposite direction to the one it was originally packed in and leave it like that for several hours or overnight. This lets the fibres relax in the opposite direction, and the curve usually disappears noticeably.
2. Weigh it down
If individual corners or edges still stick up after rolling, weights help. Place books, small boxes or similar items on the affected spots and leave them there for one to two days. Important: use light, flat objects and do not put heavy pieces of furniture directly on the pile – that can press the fibres down permanently instead of flattening them.
3. The ice cube trick for stubborn corners
If a corner keeps curling up as soon as you remove the weight, a simple cold trick helps: place three to five ice cubes on the affected spot and weigh them down with a glass or another light object. As the ice melts, the fibres align themselves in the new, flat position. This method works especially well when heat is out of the question because of the material – with natural fibre rugs such as jute you should still be careful, as they are sensitive to moisture anyway and usually flatten faster on their own.
4. Use a non-slip rug pad
A non-slip rug pad under the rug does double duty: it keeps the rug in place so that it does not slip or shift, and at the same time it helps the fibres settle evenly. On smooth floors such as tiles or parquet in particular, it is almost always worth it.
5. Just give it time
And sometimes the simplest solution is simply time. Lay the rug flat, walk over it for a while, put light furniture on it – normal everyday life often does more to flatten it than you would think.
Heat and ironing: when it helps – and what you need to watch out for
Can you iron a rug? Yes, but with care. If the first methods are not enough for stubborn creases, careful heat can make all the difference. Never put the iron or steam cleaner directly on the rug. A towel or thin cotton cloth as a protective layer is a must.
Here is how to do it: set the iron or handheld steamer to the lowest setting, lay the cloth over the crease and move slowly across it. The heat and light moisture loosen the fibres so that they lie straight again. Then weigh the spot down with a light weight while it cools – that way the result stays stable.
One point that many guides skip: this method is not suitable for every material. With jute or viscose rugs, moisture can cause stains or damage, so you should stick entirely to dry methods here. Also, always test heat on an inconspicuous spot first before you tackle the visible creases.
The right approach for each material
Not every rug reacts the same way to pressure, heat or moisture. The material helps decide which method gets you there fastest and most gently.
Wool rugs are robust, but the natural fibre is sensitive to moisture and temperature fluctuations. The gentlest way to flatten them is to roll them up the other way combined with light, evenly distributed weights. It is better to avoid direct heat or too much moisture here, as wool can otherwise felt or warp.
Synthetic rugs made of polypropylene are usually the most uncomplicated candidates. They are more flexible, less sensitive to environmental influences and cope well with both pressure and gentle, indirect heat. Creases here usually disappear faster than with natural fibres – this also applies to outdoor rugs made of polypropylene, which often also come with a non-slip backing and therefore lie more stably from the outset. Our two indoor rugs are synthetic models, too. 'Loop' is made of 100% polypropylene, 'Barefoot' of 100% polyester. That is why both cope well with pressure and gentle, indirect heat, and creases can usually be smoothed out without any fuss.
Cotton and flat-woven rugs are thin and flexible and flatten correspondingly quickly. Deeper creases, however, sometimes need a few more days under even weight.
Jute rugs call for particular care: this natural fibre is sensitive to moisture, which can lead to stains or weakened fibres. Dry methods such as non-slip rug pads, corner protectors or weighted edges are the safest choice here.
How to avoid waves from the start
Of course, the best way to deal with waves is to stop them from forming in the first place. Putting a non-slip rug pad under the rug right from the start not only prevents waves but also protects the floor and ensures a secure hold.
If you often struggle with wavy rugs, you can also pay specific attention to material and workmanship. Rugs with a firmer backing – made of latex, for example – naturally lie more stably and shift less often. That is also exactly why many of our outdoor rugs are increasingly establishing themselves as indoor all-rounders: they are built for wind, moisture and sunlight and therefore come with correspondingly robust materials that are less quick to ripple or warp.
Robust rugs that lie flat from the start
If you would rather avoid the wave issue altogether, it is worth taking a look at our outdoor rugs. They are woven from polypropylene and fitted with a VAE latex backing that provides a reliable hold on the floor – whether on the terrace or in the hallway.
'Der Gestreifte' brings clear definition to long hallways or the dining area with wide block stripes in grey/white. 'Nomad' brings the jute look into your home, without the delicate care that real natural fibres need. And 'Der Sonnige' brings brightness to darker corners of your home with its cheerful pattern in yellow/beige.
A practical side effect: all three are dirt-repellent and easy to clean – for stains, water and a soft cloth are enough, and outdoors sometimes even a pressure washer.
