There is no fixed moment that defines when a collection should be refreshed. Every brand operates in a different market, at a different pace, with different ambitions. Yet one principle remains constant. A collection should be reviewed every year.
At Coulisse, collection thinking is never reactive. Even when an assortment performs well, we take time to assess whether it still reflects today’s market, tomorrow’s expectations, and the brand’s long-term direction. Consumer behaviour evolves. Technology advances. What once felt complete may now feel quietly out of step. For major launches and international trade fairs, timing becomes even more critical. Preparing for R+T Stuttgart 2027, for example, started in 2025. Not because trends move fast, but because relevance takes time.
“A collection should never stand still. Even when it works, you need to ask if it still fits the world around it.”
- Catharina Idema. Creative Director at Coulisse
Trends don’t originate in window coverings. They surface first in furniture, interiors, fashion, and technology, shaping how people experience space, material, and comfort. Only then do they find their way into our category.
That’s why our trend research looks far beyond our own industry. From Maison&Objet and Milan Design Week to high-end interior brands, fashion houses, and global technology leaders. We observe how colours mature, how textures soften, how performance expectations rise. Not to follow trends blindly, but to understand which ones endure. Designing Tomorrow captures this perspective. It is not a catalogue of styles, but a curated framework that helps partners translate global movements into collections with depth, longevity, and relevance.
“We don’t copy trends. We interpret them, filter them, and translate them into something that truly works in window coverings.”
- Catharina Idema. Creative Director at Coulisse
A future-proof collection is never just a selection of fabrics. It is a carefully built system. Our process starts with understanding the full picture. We analyse existing assortments, pricing structures, and sales performance using in-house data tools, combined with market knowledge and hands-on experience. Often, this means reviewing physical collection books together to assess look, balance, and coherence. From there, we shape the assortment. Balancing entry, mid-range, and premium levels. Aligning design with performance. Integrating systems and motorisation where they add value. Always with a clear concept and positioning in mind.
“We look at the whole collection, not just what’s missing. Data shows us what performs, experience tells us why.”
- Esterel Roetgering. Textile Product Expert at Coulisse
The result is an assortment that feels intentional. Clear in structure. Strong in identity. Ready for the market.
Strong collections don’t end at design. They succeed because they are positioned, presented, and launched with care. That’s why partnering with Coulisse goes beyond fabrics and systems. We support private label and co-branded strategies, help design collection books that reflect how customers sell, and provide digital content, imagery, and assets that bring collections to life. From concept to market introduction. A personal inspiration session is where everything comes together. Textile experts, sales teams, and specialists collaborate to translate insights into clear direction. Not generic advice, but guidance tailored to your brand, your market, and your ambitions.
“When partners come to us, we take the time to understand where they want to go. Only then do we build the collection around it.”
- Esterel Roetgering. Textile Product Expert at Coulisse
