The material determines how a rug feels, wears and responds to stains. Look beyond colour and pattern. A dining room with chairs that are moved frequently needs something different from a bedroom where softness comes first.

Most machine-woven Merinos rugs at Karpet24 are made from polypropylene or polyester. The Loft designs, for example, are made from polyester. Always check the product specifications, as the material, backing and pile height can vary by range.

Materials at a glance

Material	Strengths	Point to consider	Good location
Polypropylene	Hard-wearing, absorbs little moisture, easy to clean	Can feel less natural than wool, depending on the weave	Living room, dining area, hallway, family home, or outdoors if the design is made for it

What is a polypropylene rug?

Polypropylene is a synthetic fibre that absorbs little moisture. Spilt drinks therefore soak into the fibre less quickly than they do with many natural materials. Exact stain resistance also depends on the construction, colour and backing.

A polypropylene rug is well suited to a busy household:

• sand and crumbs are easy to vacuum from a low-pile weave;
• the material is hard-wearing and relatively light;
• colours remain clear with normal use;
• many outdoor rugs are made from polypropylene.

Not every polypropylene rug can go in the washing machine or remain outdoors permanently. An indoor rug may have a backing, adhesive or edge finish that cannot withstand a lot of water. For a terrace or balcony, look for a design described as an outdoor rug and as UV- or weather-resistant.

What is a polyester rug?

Polyester can be made very soft and displays colours vividly. It is therefore well suited to plain, velvety and high-pile rugs. Karpet24's Loft Washable designs are made from polyester.

Polyester absorbs little water, but that does not automatically make a rug machine-washable. Its backing and finish must also be suitable. Only wash a design if the label or product page says you can. For the Loft Washable range, use a delicate cycle at no more than 30 °C; follow the label and the complete washing guide.

In a dining room, a low-pile polyester design works better than a long, fluffy pile. Chair legs move more easily and food debris is less likely to become lodged deep between the fibres.

When should you choose wool?

Wool fibres spring back naturally and retain warmth. A wool rug feels full and can last a long time when properly maintained. Its natural texture often hides small particles of dirt better than a smooth, plain fibre.

Bear three characteristics in mind:

1. A new wool rug may shed loose fibres during the first few weeks or months. This is usually surplus wool and not a sign that the rug is falling apart.
2. Wool does not respond well to hard scrubbing, lots of water or aggressive products.
3. A thick wool construction provides more insulation. This can slow the heat output from underfloor heating.

Vacuum a wool rug with a smooth floor head and without a hard rotating brush. Have stubborn or large stains treated professionally.

Viscose or just a viscose look?

Viscose is made from cellulose and has a silky sheen. Its fibres look lighter or darker from different viewing angles. This creates plenty of depth, but real viscose is sensitive to moisture. Water can leave rings, discolouration or a stiff patch.

The term viscose look describes the appearance only. A polyester or polypropylene rug can produce a similar soft sheen without containing viscose. If in doubt, check the material details on the product page.

Real viscose is best kept for a quiet room without young children or pets. Blot a stain dry immediately and consult a specialist if in doubt. Do not use a steam cleaner or wet-cleaning machine without the manufacturer's express approval.

High pile or low pile: which suits your needs?

Pile height indicates how far the fibres extend above the backing. It does not tell you everything about quality, but it says a great deal about everyday use.

Characteristic	Low-pile rug	High-pile rug
Feel	Neat and firm	Soft and warm
Vacuuming	Quick; dirt remains closer to the surface	Slowly in several directions; dirt can sit deeper
Dining chairs	Move easily	Legs can catch in the pile
Robot vacuum	Often suitable; check the height and fringes	Not every model can cross the edge or long fibres
Pet hair	Easier to see and remove	Hair becomes trapped between the fibres more readily
Underfloor heating	Usually transfers heat more quickly	Insulates more and warms up more slowly
Best location	Dining room, hallway, workspace, busy family home	Seating area, bedroom, quiet lounge area

Browse low-pile rugs if easy maintenance matters most. If you mainly want a soft surface beside the sofa or bed, compare the high-pile rugs.

Which rug suits children and pets?

Choose according to what happens on the floor at home. For children at play, muddy paws and pet hair, this combination works well:

• a low-pile construction;
• polypropylene or polyester;
• a mottled colour or small pattern that makes hair and crumbs less noticeable;
• no long loops, delicate fringes or loose threads;
• an anti-slip solution suited to the floor and any underfloor heating;
• a washable design if the size fits in your washing machine.

No material is completely resistant to cats' claws, urine or stubborn dyes. If your pet has sharp claws, a flat-woven or dense low-pile rug is more practical than one with open loops. For an accident, choose an enzyme cleaner suitable for both the material and the backing.

Can you use a rug with underfloor heating?

According to the current product information, Karpet24 rugs are suitable for underfloor heating unless the product page says otherwise. A thin, low-pile rug lets heat through more quickly than a thick, high-pile design.

Also check the requirements of your flooring and heating suppliers. They may specify a maximum thermal resistance for the combination of flooring, rug and underlay. Pay attention to:

1. Pile and overall thickness: more material holds back more heat.
2. Backing: a dense or insulating backing can slow heat transfer.
3. Underlay: include the thermal resistance of any anti-slip underlay.
4. Temperature: stay within the maximum floor temperature for both the floor and the rug.

Lift the rug occasionally during the first few weeks. Check that no moisture, discolouration or heat build-up is developing underneath.

Choose by room

Living room

Polypropylene is practical for intensive use. Polyester offers more softness and sheen. Choose high pile for comfort and low pile if you vacuum frequently or have pets.

Dining room

Choose low-pile polypropylene or polyester. Chair legs move more easily and you can remove crumbs more quickly. Combine this material advice with the 60-70 cm rule in the size guide.

Bedroom

Comfort can carry more weight here. High-pile polyester or wool feels soft when you get out of bed. Real viscose is only suitable if the risk of moisture and stains is low.

Child's room

A low-pile or explicitly washable polyester rug is usually the easiest choice. Check the anti-slip properties, washing instructions and pile construction.

Terrace or balcony

Only use a design intended for outdoor use. Polypropylene is common, but the UV resistance and finish of the entire rug are decisive. Also read the outdoor rug guide.

Frequently asked questions

Is polypropylene a good material for a rug?

Yes, especially in a busy living room, dining room or household with children. It is hard-wearing, absorbs little moisture and is easy to maintain. For outdoors, choose a design specifically made as an outdoor rug.

Which is softer: polypropylene or polyester?

Polyester is often finished to feel softer and more velvety. The final softness also depends on the pile height, yarn thickness and weaving method, so compare the product specifications.

Is a high-pile rug suitable for pets?

It can be, but long fibres hold more hair and dirt. A low-pile rug without loops or fringes needs less maintenance and reduces the chance of claws becoming caught.

Can every polyester rug go in the washing machine?

No. The backing, edges and adhesive must also be machine-washable. Wash only if the care label allows it, and follow the stated temperature and drum capacity.

Which material works best with underfloor heating?

A thin, low-pile rug usually transfers heat fastest. As well as the pile material, check the backing, any underlay and the maximum thermal resistance permitted by your flooring supplier.
