At first I had to buy a doubt this cushion. This was due to the "many" reviews the (after a short time or from the beginning) pointing to faulty zipper. Because the price is unbeatable and I've found at the fast also not really an option, I have it but then ventured. And am pleasantly surprised! I find great quality, zipper works fine, it is comfortable yet rugged - many dog pillows are worn out after a short time or lose the form, which seems to me not the case here. My dogs use it from day one. I have laid still a fleece blanket on it, but not because I think it's too thin, thus it is no longer "out loud" (has been written many times, though is less noisy but just audible) when Using '. Recommendable!
