We opted for this folding mattress, because we really have no room for a sofa bed in our guest room / office and this would take more space most of the time when they would be needed. So we ordered 2 folding mattresses to provide a guest bed for 2 persons. The mattresses were ready immediately after unpacking. We could no unpleasant odor, as often mentioned in reviews, find. A mattress was still used on the first night and it can be quite good sleep on. As on a conventional mattress which is placed on the floor. A very clear advantage is that the mattress can be carried from one room to the next quickly. So we could with our daughter sleeping in the nursery, when she was ill, or they with us without placing transversely in our bed. And to romp for children also super. For us, this acquisition has been definitely worth it. We also had only considering to buy the cheaper and thinner folding mattress from the furniture store, but the 15cm thickness of Gigapur is really great. Even though they are slightly more expensive than others, we do not regret buying!
