Grape seeds have a natural reddish-brown colour and measure approximately 5 mm in length. They are hard, smooth and irregular in shape, with rounded edges that feel pleasant inside cushions. Thanks to their compact, solid structure, they are relatively heavy for their volume, helping them lie stable and distribute warmth evenly.
Grape seeds arise as a residual stream from the winemaking process. By reusing this material as a filling, a natural by-product is given a second life. The seeds are plant-based and fully biodegradable – a circular, environmentally conscious choice for natural heat products.
