Perfect consider only sofas and armchairs before.

I use this product for all leather cases for a long time, and I can only agree with the positive review of my predecessors. The product is also suitable for smooth leather upholstery of sofas and armchairs, it gives the leather soft and colorfast, and prevents dehydration and curing. It should be noted only 2 things when applied to furniture. Point one: smooth leather is after treatment with Polyboy bit sticky for 1-2 days. Anyone who intends to throw a party in midsummer and therefore expects that this emerging women in miniskirts or shorts, or even backless, the agent should not just apply the day before. Otherwise, namely warrants that is an adhesive-orgy of the Party and the women getting up support need :-) Point Two: Polyboy impregnated, and that's when seating is not always desirable because the water-repellent effect, of course, the breathability of the smooth surface is reduced. So if, for example, has a loft, in the reign often tropical temperatures in the summer, and who wants to sit down with shorts or otherwise with the bare skin on the leather, should resort to other means. Because this is clear: By the impregnation tendency is naturally reinforced for sticking and sweating. For such cases there are other products, such as leather milk that feeds fully into the leather, but the surface is not sealed. The impregnation how she does Polyboy is good if you have children or pets, and want to protect the leather from stains, or if you have a cool apartment. In all other cases I would not necessarily impregnate seating with leather cover with Polyboy. But that is not a defect in the product, but rather a result of impregnating. And that works with Polyboy perfect.
