We may have to change our selling prices due to changing world market purchasing prices in raw materials, which affects the final cost price. 
For example, a higher oil price affects the purchase of our cold foam, polyester yarn and transport costs. We try to keep this to a minimum.
If a price has to be adjusted, after you have concluded the purchase and paid for it, but it has not yet been delivered, the difference between the old and new price cannot be recalculated.
*08-01-2025:
Due to the high demand for wood, metal and furniture foam, prices for these raw materials have risen sharply in recent months. A scarcity has developed. Transport costs have also risen sharply. Unfortunately, this has forced us to adjust our prices.
