I received it in three days which is quite fast. I laid it out on top of our spring box to let it expand, and it expanded very fast although it did have a faint odor when you got closer to it, but the odor dissipated fast. It's very warm, but now it's winter so it doesn't matter that much, I wonder how it fares in the summer though. Very comfortable and does not make noises when body shifts, so it's good for me since my hubby tends to thrash a little. So far so good, not the best or fantastic, but it's good for the price. If you got money, get more inches. And it helps back pain, so I recommend it.
