Natural, warm and beautiful: Wool felt is a fabulous material. Bernadette Ehmanns and Mathias Hey have been experimenting and working with this high quality natural product for over 15 years now. In the mid nineties they discovered wool felt for the object and furniture sector. In 1999, they founded HEY-SIGN. Since then, HEY­-SIGN has established itself as a pioneer and trendsetter for wool felt in interior design. With creative products and ever changing, surprising designs, HEY-­SIGN has significantly been responsible for felt to be naturally integrated into the world of living. A consistently high quality standard and a creative approach to design characterise the founder's philosophy behind HEY-­SIGN.


Wool felt offers endless creative design opportunities. All HEY-SIGN’s felt products convince with good design and great attention to detail. The current product range contains about 250 articles from home accessories such as cushions, boxes and table decorations through furniture, seat covers up to room dividers, luminaires and carpets, available in four different material thicknesses and more than 50 modern colours. Felt is ideal for the realisation of contemporary interior design concepts in the private, public and commercial sectors: Wool felt is permeable to air, light resistant as well as resistant to abrasion and deformation. It is easy to maintain and durable, sound-absorbing, provides a pleasant room climate and good acoustics. HEY-SIGN uses these natural benefits and realises individual, custom-made solutions as well as special cuts for interior designers, architects and corporate clients. A perfect service based on individual needs. 



The design consistency, typical of all HEY-SIGN collections, characterises the architecture and furnishing of the black, cubic and newly built head office. For the interior design of reception, studio, kitchen and offices, felt has been used as a matter of course: Lighting, seating, table covers, panels and room dividers are all made of this beautiful natural material. In the production hall, felt dominates the scenery too. The employees are surrounded by felt. After cutting by CNC, all following production steps take place using traditional handcrafted methods: from stamping, sewing and weaving to the packaging of goods. How perfectly felt provides for a pleasant room climate, good acoustics and inspiring atmosphere, can be experienced by all HEY-SIGN employees every single day.


HEY-SIGN has specialised in the processing of high-quality wool felt. Only 100 % pure new wool is used for the production of HEY-SIGN accessories, bags, furniture, lighting and rugs. The raw material is best merino wool and predominantly comes from Australia and New Zealand. The material is left natural; there isn’t any chemical treatment. The products are mainly manufactured by hand at the HEY-SIGN manufactory in Meerbusch – “Handmade in Germany”. Felt is an entirely natural material with plenty of positive effects: it is permeable to air and purifies the air. Its sound-absorbing properties ensure tranquillity and improve indoor acoustics. Felt balances humidity, insulates against cold and heat, repels dirt and absorbs unpleasant odours. Furthermore, wool felt is particularly kind to human skin.


Due to its high-quality standards, HEY-SIGN was the only felt manufacturer, honoured with the Woolmark-label by “The Woolmark Company”. In 2007 felt from HEY-SIGN has been tested and certified according to the strict guidelines of “The Woolmark Company”. Since then, all HEY-SIGN products carry the Woolmark sign – the quality seal for pure new wool. All products in 3, 5 and 8 mm thicknesses are additionally certified according to Oeko-Tex Standard 100. 


HEY-SIGN manufactures its products based on high quality wool felt, a naturally renewable resource. After the elaborate production of wool felt, HEY-SIGN follows respectful treatment practices while processing. HEY-SIGN develops and manufactures in Germany. Parts of the collection are produced at workshops for adapted work and local suppliers for metal, wood and leather. The transport distances are short. This conserves resources and actively protects the environment.
