Absolutely horrible. Not only did it inflate incorrectly, but it is nowhere near the 12 inches it’s supposed to be. You’ll see the photos and it’s barely 8 inches thick after having two uninterrupted days to puff up. There is a significant hump on the left hand side of the mattress where it inflated a ridiculous amount more. The photo doesn’t do the issue justice. The worst. Tried contacting customer service where the chat not told me to return it. Would be happy to if someone wants to pick this piece of junk up. Called the customer service number and they’re closed. Never again.
