When these arrived they were wrapped with a cover that was stapled to the seat I nearly had to destroy the cushion to remove the cover. These are used in my house only very rarely but I think If a heavy person was to use them often they would not last long.
Gave this as a present to my father in law. He seems to have done everything it said in the instructions but not much sign of any mushrooms. Possibly he has not done it right or we have no patience but still waiting for a crop.
