At first glance, composite foam resembles a typical recycled material that is anything but purely manufactured from various recyclable materials. Plastic recycling usually results in an inferior, not entirely homogeneous material whose properties are usually worse than those of the individual starting materials, so that the term "downcycling" is more appropriate for the resulting material.
In the case of this material, however, the situation is clearly different: although the composite foam is a mixture of different starting foams, it is exclusively polyurethane foam. The composition of foams of different densities, which have been torn into small pieces and bonded together via a foam matrix surrounding them, results in a material that, in terms of its use as an upholstery material, brings together the positive properties of the individual components in a single material. The composite creates a pleasantly firm and thoroughly homogeneous upholstery foam on which it is very comfortable to sit. It has the resilience to prevent a noticeable deep sink-in and yet conveys a comfortable seating sensation.
Like many polyurethane foams, this composite foam yellows when exposed to light. This can already be seen in the "fresh" material just coming out of storage. We therefore recommend a (preferably light-proof) cover if you want to use it as a seat cushion. On the other hand, if you want to use it as protection for sensitive objects, you can also use the composite foam raw.
