We didn't realize how firm this mattress was when we bought it. We slept on this mattress at an airbnb and loved it so much we asked the owners for the link to buy our own. When ours came it was so firm and dense. It was uncomfortable even to sit down on it too fast. We moved it from our room to our guest room, and someone who came to stay with us said the mattress was so firm they slept on the couch instead.
